Can Drones Really Get National Airspace Access?
coondoggie writes "There is a push by a variety of proponents to give unmanned aircraft more free rein in US airspace, but safety is a major hitch in that effort. The Federal Aviation Administration said this week that data from the Customs and Border Protection (CBP) agency, which flies unmanned systems on border patrols, shows a total of 5,688 flight hours from Fiscal Year 2006 to July 13, 2010. The CBP accident rate is 52.7 accidents per 100,000 flight hours. This accident rate is more than seven times the general aviation accident rate (7.11 accidents/100,000 flight hours) and 353 times the commercial aviation accident rate (0.149 accidents/100,000 flight hours)."
An FAA executive noted that an "accident" refers to a situation in which "the aircraft has done something unplanned or unexpected and violates an airspace regulation."
...is firing a hellfire missile a airspace regulation violation?
Running the numbers, that means they're looking at 3 incidents in 4 years. That seems like a pretty meaningless exercise to me, especially then comparing that number to commercial flight with millions of hours logged.
I am a military Helicopter pilot and I have literally come back with a UAV sticking out of the side of my aircraft after a mid-air with a small drone. There are lots of growing pains with these things, and they are no where ready for integration in the national airspace system. A growing conflict with military use of UAVs is that they are often being operated by non-pilots(cheaper to train). In many cases the smallest drones are operated by infantrymen who throw these things into the air and rely on big sky theory to separate them from the aircraft providing Close Air Support. Non-pilots typically have less diversity of experience and a lot less air-sense when it comes to situational awareness.
The most likely user of this technology is Law Enforcement. The last thing civil aviation needs is some jack-hole beat cop throwing these things into the air to look for a guy on a stolen bicycle and have a mid-air with an airliner on approach because he dose not understand what is going on above him, or have any responsibility for his actions because his personal safety is not directly tied to the operation of his aircraft. They cant be trusted to use tazers, why the heck would we give them UAVs?
I'm a pilot, paramedic and software engineer. My flying is personal but I try to take a "professional" approach. I agree that there are a lot of not so great pilots out there but the most basic pilot has had a bunch more training than 99.99% of the drivers out there. A typical "commercial" pilot with a commercial certification and an instrument rating (and typically multi-engine in both) has about 3-5 times the training typically required for a CDL.
Pilots and the flying industry are one of the most regulated endeavors in modern society. A good chunk of those regulations are "written in blood" from past accidents. Besides a few thousand pages of official FAA regulations there are thousdand more in ACs, TSOs and even industry standards like SAE, Milstd, ASTM, RTCC, etc. One big part of the problem is there are no standards for UAVs or UAV operators.
Flying is still heavily dependent on "see and avoid". The reality is we probably still avoid as many or more crashes from "big sky theory" than "see and avoid". The people who want to fly UAVs mostly want to fly them where the risk is highest - down low and over population areas. Also the UAV accident rate isn't as sparse as it sounds. There are well over 100,000 hours factoring in overseas usage. Even if you subtract out combat or unknown losses the accident rate of the UAV business is abysmal. Remember this is the industry that gave us unencrypted classified combat video.

The argument that there is no pilot so the risk is minimal is disturbing. A predator is almost 30' long and a 48' wingspan - 1200# empty and over a ton fully loaded. This is comparable to most 4 seat trainers. Several of the private drones are smaller but have even less QA and little to no redundancy.
The first and only NSTB report on a drone crash is at http://www.ntsb.gov/ntsb/brief2.asp?ev_id=20060509X00531&ntsbno=CHI06MA121&akey=1. It cites the typical chain of errors as well as a series of poor design decisions. It also notes the wreckage path indicated a flat approach and a wreckage path of almost 100' with jet fuel scattered around the crash site (there was no ignition). The operations console being used had suffered approximately 16 lockups in the 4 months prior to the crash and suck lockups were viewed as normal and acceptable. The normal "lost link" procedure normally keeps the aircraft flying a predetermined route over unpopulated areas until control was restablished but improper recovery on the crash failure caused the engine to be turned off.
The lost link route procedure was called out in the NTSB report: "Another contractor, Organizational Strategies, Inc. (OSI), provided the coordinates for the lost-link waypoints to CBP. OSI reported that it developed the waypoints using an Internet satellite website. CBP reported that it also used the same Internet satellite website to verify the location of the waypoints. According to this website, some of the website's imagery is 1 to 3 years old. Neither OSI nor CBP used additional methods to confirm that the waypoints were not located over populated areas." No indication of the resolution of the satellite imagry used - and no requirement for direct verification.
In fairness the CBP is actually one of the more rigourous operators of UAVs. Their pilots are required to be certificated pilots with at least 200 hours of actualy flying time and 200 hours of UAS flying time. They also use specific TFRs to provide seperation and maintain contact and obtain clearances from ATC. Not all FAA "Certificates of Authority" require this level of coordination or training. Many smaller operators operate close enough to the ground or restricted terrain or existing restricted airspace viewed to not interfere with existing flight activity.
The simple reality is the UAV industry is about where manned flight was in the 30s. They hav
