In general it's fantastic that the FAA is finally loosening up on drone regulation. Overall the technology has huge potential and is pretty safe to operate in most places if done responsibly.
Class B airspace is not one of those places. FOD can very easily take down an aircraft. These guys are going to get the book thrown at them, and they deserve it. It's very much in our best interest as a tech community to weed out people who act with such disregard. If there's an appearance that we aren't responsible enough for this, there will be a backlash and we will have a much, much shorter leash.
It's probably going to be a tension that we see repeated as we explore drone tech, since Class B airspace is often located near large cities that would be good target markets for drone-based businesses.
Even if the FAA grants the low-altitude airspace to drone traffic there will still be problems. The larger, faster high-altitude drone corridors with the most dangerous traffic would be placed the closest to other air traffic. Having better guidance, transponders, and collision avoidance is a start, but nowhere near sufficient. They still won't be responding to ATC guidance and commands. I imagine we'll probably see a tiered exclusion zone around airports for this reason.
I've seen several news stories here in BC and other places on the west coast about rescue and fire fighting planes which were grounded due to unmanned drones in their airspace. One idiot hobbyist with no regard for anyone else can threaten thousands of acres of forest and countless human lives.
Shut these people down, bring the hammer down on people being idiots, and let the responsible people keep going.
I mean, this isn't even someone toying around with a quad and not realizing there was serious air traffic in the area. They repeatedly ignored the FAA telling them to knock it off with the drones around jumbo jets.
Frankly, I think the disparity between the cost of drones and the amount of damage that they can do in irresponsible or unskilled hands has put us in an untenable situation. We need to quickly develop technological countermeasures against unlawful drone use, or we can expect to see a draconian law enforcement response, just as we have seen in another similar arena: hacking.
Here's the thing - this problem will only become more common. A side effect of scientific and technological progress is that individuals wield ever increasing amounts of destructive power.
Technological countermeasures will only lead to an arms race, in which the defender is always at a disadvantage.
In the very near future, how are we supposed to defend against a high-school kid who accidentally created a deadly pathogen? How about a deliberate bioattack? We really need to figure this out, and sooner rather than later.
Yeah, from what I hear Class Bravo airspace is one of those areas that you can flying toward in a Cessna 172, ask to enter, and be pretty much told "no thanks, not right now". (N.B. Not a pilot, you're all safe).
I sometimes fly from YYJ (class C) and they're quite adept at fitting the Cessnas in between the 737s and dash-8s. There's no low-level class B here in Canada (only above 12500ft), but the Vancouver class C terminal zone is probably equivalent to the class B around SFO.
This is correct. To enter Class Bravo airspace, one must have clearance from Air Traffic Control. Pilots are free to request clearance through Class Bravo, but it's not always granted. For example, flying a Cessna 172 out of San Carlos Airport in the San Francisco Bay Area, it's very convenient to travel through the nearby Bravo airspace of San Francisco airport. Sometimes it's granted, other times we have to go around.
Furthermore, having obtained a Bravo clearance, you must pay close attention to and promptly obey any instructions from ATC (which can be of the form "turn left 10 degrees immediately for traffic avoidance"). By contrast, controllers have no means to track drones or communicate with their pilots.
Not really, a licensed private pilot can fly into class bravo airspace in something like a 172. Happens all the time and the NYC controllers are actually quite good with this. Flew with a pilot friend and ATC took him right over Manhattan and JFK in a little Cessna. However if you act like one of these drones and fly in with no radio comms and no transponder, that's when they scramble the fighter jets.
The issue I see from looking at the photos on the site is that they were flying in airspace that's frequently occupied by 'real' air traffic and were blatantly violating the rules about where/when you can fly these things. The FAA told them to stop and they kept going anyway. Those rules aren't just bureaucratic fluff, but are there because there are real people flying real airplanes/helicopters in those areas.
I'm all for the whole "let's just ignore the rules and be disruptive" attitude that some new companies take these days, but you can't just go flying these things into airspace that's been designated for legit air traffic and expect to not get the book thrown at you. Heck they were doing this over NYC, they're lucky the Feds didn't decide to go all ballistic with the "we're going to treat you like a terrorist" stuff.
I suppose that from a practical perspective they are lucky that the feds didn't abuse their power by treating air traffic violators as if they were deliberately attempting mass murder, but it's a bit disturbing how plausible that scenario is.
Now that you mention it... there's pretty much no point in the TSA's involvement in passenger-side airport security when airplanes are comparatively much more easily attacked from the outside. If I was a terrorist, I know which method I'd choose.
Wouldn't that be detonating the bomb on the airport instead? This whole security theater only plays into terrorists' hands. Yes, it may be more difficult to board a plane with explosives nowadays, but on the other hand we have hundreds of people stuck in a line trying to pass through security one-by-one, dropping potential liquid explosives into a single bin!
I'm all for the whole "let's just ignore the rules and be disruptive" attitude that some new companies take these days, but you can't just go driving these things into roads that've been designated for legit taxi traffic and expect to not get the book thrown at you. Heck they were doing this in NYC.
That's just not a similar comparison. Would you be jumping to Uber's defense if the drivers just started ignoring one way street rules, or perhaps if they just blatantly used bike lanes? That would be a similar situation.
Here's a report from the NTSB about a helicopter flying at normal speed and altitude which hit a red-tailed hawk and resulted in the deaths of 8 people.. so there's that..
Sometimes well, sometimes not. Bird strikes are relatively rare, but do happen. I've had two. One tiny guy on the wind screen on landing at about 150mph which caused no damage and one on the nacelle of a jet engine at around 270mph that did cause structural damage. I also own a little DJI phantom "drone" and have no doubt that it could snuff out a turbine engine if it was ingested or cause significant structural damage. Unfortunately the FAA can't go after birds with fines for busting class B airspace, but they can and should nail drone operators.
The little copters are really awesome to play with but the FAA needs to start upping the enforcement. You need to be licensed to talk on a ham radio, you should be licensed to fly a drone. Not a full on pilots license, but written tests on airspace every year or two. It would be nice if future drones continuously transmitted the operators credentials on a publicly available frequency.
People keep bring that up, but they actually take great pains to keep birds away from places that airplanes fly, because of the danger. For instance they use falcons to ward off bird packs from airports. Just one of the things they do. But birds are still a danger, we just can't control them.
But this? This is controlled by a human. So what is the excuse? Personal freedom? That's not going to cut it with the public.
People can easily route air traffic from their smartphones like the air traffic controller game. You have a bunch of people directing traffic in the game, and you find the most commonly agreed upon flight path and use that to direct the pilots! It's like how Duolingo crowd sources language translations. It's so obvious!
I was being facetious but now that I think about it, it does seem fairly inevitable that one day air-traffic control will be consider to have too low a margin for error to entrust to human operators.
If a pilot or passenger sees a bird, balloon, or odd reflection these days, it's a "drone". Be skeptical about the recent uptick in fear mongering about the number of drone sightings in the vicinity of airports and airplanes.
As someone who has spent a fair amount of time in small, four-seater airplanes and also owns a popular quadcopter model, I always feel compelled to add some color to these threads about drones.
When I'm flying my quadcopter, it's extremely difficult to spot once I've lost continuous sight of it. Look away for a second, and you're staring at an empty sky. Even when it's just a couple hundred feet away and you know exactly where to look, the thing is nearly invisible in the air.
Sitting in the passenger seat of a Cirrus or Cessna, I've always been surprised by how difficult it is to spot nearby aircraft. Whole planes, orders of magnitude larger than a consumer drone, are much harder to spot than you'd expect. Even when ATC alerts us where the traffic is, you rarely pick it up visually until much later than you'd anticipate.
Maybe more importantly, many modern drones have geofencing that prevents them from flying into the restricted airspace around airports.
Combining my experience in both situations with the geofencing around restricted airspace, I find it incredibly hard to believe that folks are honestly spotting consumer quadcopters from airplanes in this quantity. It's just not credible at all if you've spent much time around either or both hobbies.
Well think again, as a commercial pilot with 16 years of experience I can tell you that sometimes you can even see what type of bird you crossed. And it has to be quite close to be a problem to you, so pilots are reporting drones that could be ingested in to the engine and create a fire in short final.
Not all reports are accurate, that's true. But most of us don't go reporting ufos these days...
For example, this is a report from this year that the FAA categorized as a drone encounter here in my hometown of Atlanta:
> A VFR aircraft receiving ATC service reported passing an object approx 500ft below him at 095. The pilot described the object as round circular, red in color, and reported it could have been a drone or a balloon. A80 ATC did not observe any targets on radar in the vicinity of N7745.
A drone or a balloon? Might as well just chalk it up to swamp gas at that point.
Having been in aircraft looking out and having watched from the ground as my own quadcopter disappeared into the sky significantly closer than 500ft away, I find it extremely challenging to see most reports like that as credible. Yet, the FAA has no qualms with aggregating this junk data into a scary story to sway public opinion. Disappointing.
I'm curious. Have you personally, definitively witnessed a consumer drone in restricted airspace during approach?
Well fair enough, I was talking about commercial pilots reports in final approach or take off. I guess that VFR flights are going to be less precise, also VFR flights are more probable to flight themselves in to a zone where drones can be flown legally. They are going to be sharing airspace much more than drones and airliners.
I haven't seen a drone yet, I do have like 12 or so laser reports under my belt. They are annoying (mostly kids being "funny") but not that dangerous, it's impossible for a person to track perfectly the cockpit at the speed and distance we are traveling for them, so you only get to see a short red or green flash and the laser beam moving around.
I eventually expect to have some air-miss with drones from dumb plane spotters or a guy that's taking some video from above without realizing that he is in a final approach zone. Not a big worry right now for me, my friends or other pilots I fly with.
But take into account that just a drone strike in an engine can cost more than 1 million dollars in repairs, or up to 5 or 6 of an entire engine depending on the damage. Plus the losses and delays caused by the plane being grounded for some days. Also although much more unprovable, it can lead to a crash or at least a runway excursion while landing, or total hull loss once stopped on the ground and with passengers evacuated, due to an unextinguished engine fire.
Don't get me wrong. I don't in any way condone people flying drones in restricted airspace. There are so many other (safe) places to fly that it makes no sense to endanger people and/or property by flying in dangerous areas.
I don't even question that these encounters are happening occasionally, because there are always reckless morons out there to ruin things like this for everyone, but I do question the credibility of this recent hysteria around drones.
Speaking of the laser pointers, I got zapped in the eye with a green laser pointer at night once while sitting in the passenger seat. I happened to be leaning over and looking down at the ground right when they were targeting us. The intensity was much greater than I would have expected a few thousand feet up. It wasn't quite blinding, but super disorienting for a few seconds. Hard to believe that anyone would think it's okay to do that.
>For civil penalties in excess of the dollar limitation on FAA’s assessment authority (for other than hazardous materials violations), the FAA has authority to compromise a penalty. This type of action is initiated when the FAA sends a civil penalty letter to an entity. The letter advises that the FAA believes the entity has violated a statute or regulation. The letter also states that the FAA is willing to accept a penalty of a specified amount in resolution of the matter.
If I understand the process correctly, this is essentially a settlement offer. The FAA is suggesting that the company pay $1.9 million for its misdeeds; if the FAA and SkyPan can't come up with a compromise, it gets handed over to the US attorney's office.
Point being, this will just dissuade people from trying anything new in the space, when sensible legislation should be setup to stop people from trying "stupid" things in this space. The existence of sensible legislation seems to be lost in this media fervor.
Though I don't assert they're analogous danger risks, I wonder if eventually unsanctioned drone operations in certain airspace will carry with it charges akin to those who shine lasers at pilots in airplanes.
For the people here who say that the drones can't take down an airliner or a small Cessna how many lives are you willing to bet on it? The live of two people typical of a Cessna 172, the lives of a few hundred passengers in a Boeing 777? What we are forgetting is the human factors here too. It is not just a collision that might damage an engine, a wing, or a tail section. It is also the distraction the pilot now has to deal with very close to the ground. Now instead of paying attention to the landing and other aircraft the pilot has to figure out what was that noise that just collided with it. Especially under instrument meteorological conditions. In fact, FAA has regulations for airlines to have a sterile cockpit (100% concentration on the landing and no outside distractions) due to accidents that have happened and loss of life while pilots were distracted with other things even higher than the 400 ft.
edit: In summary/TL;DR SkyPan was explicitly allowed to operate a 55lb drone commercially if they stayed at an altitude less than 400ft, the drone would fly home after a lost connection for safety, they were more than 500ft from people, and were 5 nautical miles from an airport UNLESS THEY HAD WRITTEN CONSENT from air traffic control authority.
The FAA has only issued 333a exeptions for commercial drone use to ~399 firms, one of which is SkyPan. Exemptions are case by case. They give these FAQs[1] on their site breaking down what that permit is.
Here are some excerpts from the SKYPAN exemption. These are issued as letters if you see the link[2] below and are evaluated on the case by case basis, following are relevant intersting excerpts specific to skypan[3]:
ESTABLISHED PRECEDENCE
====================================
> FAA found that the enhanced
safety achieved using an unmanned
aircraft (UA) with the specifica
tions described by the petition
er and carrying no passengers or
crew, rather than a manned aircraft of signi
ficantly greater proporti
ons, carrying crew in
addition to flammable fuel, gi
ves the FAA good cause to find th
at the UAS operation enabled
by this exemption is in the public interest.
TYPE OF VEHICLE
====================================
This is the operating drone Specs:
> Operations authorized by this grant of ex
emption are limited to the Align T Rex 700E
F3C when weighing less than 55 pounds in
cluding payload.
GENERAL RULES (speed, altitude, oversite)
====================================
> may not be operated at a speed exceeding 87 knots (100 miles per hour).
> The UA must be operated at an altitude
of no more than 400 feet above ground level
> All operations must utilize a visual observer (VO). The UA must be operated within
the visual line of sight (VLOS) of the PI
C and VO at all times. [I think PIC is person in control]
OPERATING AROUND AIRPORTS (SkyPan)
====================================
The UA may not operate within 5 nautical mile
s of an airport reference point (ARP) as
denoted in the current FAA Airport/Facil
ity Directory (AFD) or for airports not
denoted with an ARP, the center of the ai
rport symbol as denoted on the current FAA-
published aeronautical chart, unless a lett
er of agreement with that airport’s
management is obtained or
otherwise permitted by a COA issued to the exemption
holder.
OPERATIONS AROUND CITIES (SkyPan)
====================================
All Flight operations must be conducted
at least 500 feet from
all nonparticipating
persons, vessels, vehicles, and structures unless:
a.
Barriers or structures are
present that sufficiently pr
otect nonparticipating persons
from the UA and/or debris in the event of an accident. The operator must ensure
that nonparticipating persons remain under
such protection. If a situation arises
where nonparticipating persons
leave such protection and
are within 500 feet of
the UA, flight operations must cease immediately in a manner ensuring the safety
of nonparticipating persons; and
b.
The owner/controller of any
vessels, vehicles or struct
ures has granted permission
for operating closer to those objects and
the PIC has made a safety assessment of
the risk of operating closer to those
objects and determined that it does not
present an undue hazard.
[3]In the letter the decision is based on other proposals, so some of these rules are possibly boilerplate. However, as an exemption, when I say "specific", I mean these are grants, so these are rules and allocations the entity (skypan here) must follow, not neccessarily applicable to other providers.
Yeah. No drones/RC aircraft/large kites/balloons within 5 miles of a major airport without contacting Air Traffic Control
Is somebody going to come after you for the drone toy you got at Target for $30, flying 5 feet off the ground? Probably not -- The FAA doesn't regulate throwing basketballs in the air either. Is it illegal? Probably! I wonder what ATC would say if you asked permission to fly your drone under 25 feet in your yard ;)
I agree that operating drones in restricted airspace is stupid and ignorant, but it's exceptionally unlikely that drones of the size flown by most hobbyists (<8 lb, just a few feet wide) would cause that sort of damage to a commercial airliner.
Hail is far less than 8lb and can crack an airplane's windshield. It's a function of momentum and density. If the drones are designed to be fragile when impacted, maybe structural damage can be avoided, but sucked into an engine all bets are off.
I'm on mobile and didn't watch the video, but a commercial airliner travels something like 500mph, 8 lbs of drone is pretty damaging at that speed. I know they take significant precautions against eg birds.
They do abuse engines a lot for testing (http://www.gereports.com/post/101784637445/where-jet-engines...) and the golf ball hail seems pretty challenging. I doubt an R/C drone is going to give the engine much trouble. Not that it couldn't damage the engine, just that it wouldn't take out the airplane.
Personally I think the drone discussion is more about the safety concerns they aren't talking about rather than what they do talk about. A lot of security scenarios are compromised if you can accurately deliver a small amount of payload from the air into an arbitrary space.
I think the FAA would do well to allow property owners, or their designated agents, a free hand to do what ever they want to drones over their property at altitudes below 400'. Whether it is shoot them out of the sky, or capture them with nets and resell them on the used drone market. Drone pilots would self limit their flying activities at that point I suspect.
Frozen turkeys almost completely disintegrate, they're mostly water. Drones have components that won't completely disintegrate, and those pieces can cause significant nozzle or turbine blade damage. An engine loss in turbine powered aircraft isn't exactly routine, but shouldn't result in the loss of the aircraft. It's still considered an emergency though. And a huge amount of air traffic isn't turbine powered, it's smaller general aviation aircraft with normally aspirated engines.
Agree but you can't have it both ways, a propeller plane is going to destroy the drone with a prop strike or the drone will bounce off the wing or vertical stabilizer. Any jet engine that ingests a drone will contain the damage to the engine itself (expensive, but again probably not the loss of an aircraft). And that is the "funny" part about the drone conversation in the press, it is highly unlikely that you'll ever bring down an airplane with a hobby (< 10lbs) drone. You can with a 1/10 scale jet powered model airplane, and those have been flying "unregulated" for over a decade. So why drones?
And I think it is the other things that hobby drones can do which is the actual target of regulation. Photographing sunbathing movie stars as a fairly banal example, but much more severe scenarios as well. And giving the property owners immunity from prosecution for destroying somebodies drone over their property would pretty much quench a lot of those (and create some interesting new markets like net guns)
Composite propellers aren't assured of surviving a drone strike. If any propeller were to crack essentially anywhere along its length, you're talking about tens of thousands of pounds of shearing force in operation. If the propeller separates, the imbalance very easily could cause the engine to dismount. If the engine departs the plane, the plane is no longer properly weight & balanced and will not be glidable, it will tail spin into the ground uncontrollable. So I completely reject the "is going to destroy the drone" comment.
Read FAR 33 and 35, and then also do a simple Google search about engine containment failures. They can be catastrophic despite the design and testing done. So I reject the "will contain" comment.
The difference with drones and hobby model aircraft is a moron can get and keep a drone airborne, model airplanes have analog input by a human and if you don't know how to fly "by the stick" with such airplanes, it's an expensive mistake very quickly.
In theory I have little problem with the idea of property owners being able to destroy overflying drones, but in practice this is covering vigilantism and is not compatible with civil society.
Inevitably there will have to be some regulation requiring drones to identify themselves (there's a color coded flashing LED proposal, that's like a license plate); from which police can look up the owner and operator and current flight plan; and then issue directly to the operator in real time either an order to cease current operation (return to home) or reveal operator location/ID.
We just can't have people shooting things out of the sky, and having them drop on someone's dog or kid in the back yard. It'll start neighborhood feuds that will not end well at all.
You miss my point completely. Radio controlled aircraft all have a similar threat profile to commercial and private aviation. That has been true before the big drone explosion. Drones don't pose any more threat than any other R/C plane[1].
And yet there has been a concerted effort to call out drones as a threat, so why? And the only reason that comes up is that drones in the form of quad/hex/octa copters can do things that regular R/C planes can not, and those things are threatening to people and privacy on the ground, not the air. So why not talk about the real problem instead of this "made up" problem?
[1] Ok so balsa or styrofoam gliders are probably not on anyone's list of threats.
The major danger of birds is that they travel in flocks, which greatly increases the probability of multiple-ingestion events taking out all engines.
I agree that a drone hitting an airplane could be awful, but the linked video shows a ~8ft across multicopter shearing the winglet off of an airliner, which is a comically implausible bit of scare-mongering.
Class B airspace is not one of those places. FOD can very easily take down an aircraft. These guys are going to get the book thrown at them, and they deserve it. It's very much in our best interest as a tech community to weed out people who act with such disregard. If there's an appearance that we aren't responsible enough for this, there will be a backlash and we will have a much, much shorter leash.
