Message-Id: om: "Larry Dighera" wrote in message news ![]() [...] Do you know how many occur in any given time frame? Many international Part 91 flights occur each day. So the answer to my yes/no question would be...? No, you don't know. Implicit in your question is the notion that, because there are less international Part 91 operations than domestic, there is no problem compromising their safety. I do not hold that view. To intentionally design the NAS in such a way as to permit UAV operation at reduced vision standards is unprofessional, unacceptable to public safety, and negligent. Unprofessional? Negligent? Reduced vision standards? What reduced standards? Are you implying that the ground based crew operating the UAV would be able to meet the vision standards required of a certificated airman and mandated by Code of Federal Regulations, Title 14, Volume 2, Chapter 1, Part 91, Subpart A, § 91.113(b): When weather conditions permit, regardless of whether an operation is conducted under instrument flight rules or visual flight rules, vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft. solely through the use of video equipment on-board the UAV? If not, I would characterize the UAV pilot vision standards as reduced from those required of certificated airmen. And how long do you estimate it will take for UAVs to be operating beyond the national boarder corridors, given the national hysteria? I make no assumptions - including one regarding "hysteria". The only hysterical one here appears to be you. ![]() What has lead you to that conclusion? ...do you expect the team operating the UAV to actually take responsibility for their failure to see-and-avoid? You're assuming facts no in evidence. You didn't answer the question. :-) From the past behavior of military in MACs with civil aircraft, I would expect the military to deny all responsibility. Perhaps, but the NTSB would still make their ruling, wouldn't they? The NTSB has shown a significant lack of impartiality in at least one civil/military MAC case: http://www.ntsb.gov/ntsb/brief.asp?e...13X33340&key=2 This begs the question, how is the UAV's conspicuity planned to be enhanced? Has anybody said this enhancement would be made? Unfortunately, there has been no mention whatsoever of enhancing the conspicuity of UAVs operating in Joint Use airspace in any of the literature I have read. It would seem prudent to equip the UAV with a bright light on the front of the UAV, so the pilot on a head-on collision course with it might be able to see it in time to attempt to avoid it. The UAV might also be equipped with TCAS to assist in warning of an impending MAC. |

Implicit in your question is the notion that, because there are less international Part 91 operations than domestic, there is no problem compromising their safety. I do not hold that view. You're assuming a significant rise in the danger to other aircraft (*You*, not I, separated Part 91 traffic from the rest.) I'm not yet convinced that adding remotely piloted aircraft to a relatively rarely-travelled slice of airspace over very sparsely populated border areas raises the danger to pilots enough for me to be worried. Frankly, I'd give much better odds to having an in-flight fire or engine failure than a MAC with a remotely piloted aircraft. The Big Sky is much bigger in the border areas discussed in your articles. Are you implying that the ground based crew operating the UAV would be able to meet the vision standards required of a certificated airman... solely through the use of video equipment on-board the UAV? I implied no such thing. However, I'm curious to know why you're implying they *wouldn't* be able to meet those requirements. Are you aware of all the capabilities of the UAV's you're talking about?

On Thu, 22 Apr 2004 16:17:37 GMT, "Tony Cox" wrote in Message-Id: et: I note that there is currently no requirement for certification, even medical requirements [for UAV operators]. Can you provide a citation that supports that statement? It's a quote in your original post, attributed to one William Shumann:- "Currently, there are no FAA regulations dealing with the certification of UAV pilots, aircraft or (commercial) operators," he said. Aircraft operation in the NAS by an uncertificated "pilot" would seem to violate FARs. It is scary beyond belief if true. Imagine the uncertified pilot of the UAV safely on the ground simultaneously monitoring video from the front, above, below and to the sides while attempting to spot intruders on the ground. How much time is going to be devoted to traffic scan compared to ground scan? Will the operators receive recognition for avoiding collisions or spotting illegals? How will the public be assured that their priority is safety, and not mission success as is inherent in manned aircraft where the pilots have their lives on the line in avoiding collisions? What assurance do we have that he won't have a heart attack, or loose consciousness, or a whatever? It's my understanding that it takes a team of about 7 to operate a UAV. Perhaps that level of redundancy might mitigate the concerns you raise. However, 7 border patrol officers on the ground might be more effective in preventing illegal entries. I'm of the opinion that physically being in the plane sharpens your mind up. When I fly, I'm constantly "on edge" and ready to react instantly to any problem. It's my bum on the line too. Frankly, I'd never expect that level of alertness from a remote pilot, slouched in a chair drinking his coffee, thumbing through "Playboy" during the dull bits of a mission, scratching his butt and wandering off to the bathroom whenever he feels like it. All he risks is his job. Those are my concerns as well. |

I'm not yet convinced that adding remotely piloted aircraft to a relatively rarely-travelled slice of airspace over very sparsely populated border areas raises the danger to pilots enough for me to be worried. Intentionally compromising air safety is always a bad idea. Once the UAV 'camel' has its nose under the tent, you can bet that you will be sleeping with it soon, fleas and all. Frankly, I'd give much better odds to having an in-flight fire or engine failure than a MAC with a remotely piloted aircraft. How did you arrive at that point of view. Do you have any data to support it? Giving odds or taking chances is an inappropriate approach to air safety. The Big Sky is much bigger in the border areas discussed in your articles. The "Big Sky" is a total myth. Any rational system that relies upon chance to insure air safety is doomed to failure. I hope you're not an FAA employee. Are you implying that the ground based crew operating the UAV would be able to meet the vision standards required of a certificated airman... solely through the use of video equipment on-board the UAV? I implied no such thing. You questioned my use of the term 'reduced vision standards'. That lead me to believe that you felt that UAV operators would be held to the same (not reduced) vision standards as certificated airmen. If your questioning of my use of the term 'reduced vision standards' did not imply your belief that they UAV operators would be held to the same standards as certificated airmen, what were you implying? :However, I'm curious to know why you're implying they *wouldn't* be able to meet those requirements. Are you aware of all the capabilities of the UAV's you're talking about? I'm not so I can't make too many assumptions either way. The military has not disclosed to me all the capabilities of their UAVs. :-) However, unless there is high-resolutin, color, binocular vision in all quadrants, the UAV operators visual capability to see and avoid will be substandard to that required of a certificated airman.

... Aircraft operation in the NAS by an uncertificated "pilot" would seem to violate FARs. I suppose that depends on how you define "Aircraft" and "pilot"... It's my understanding that it takes a team of about 7 to operate a UAV. Perhaps that level of redundancy might mitigate the concerns you raise. However, 7 border patrol officers on the ground might be more effective in preventing illegal entries. Now I don't understand the logic. What does a UAV provide that a 182 doesn't? Is it significantly cheaper to keep in the air? Do the "team of 7" work for less money than a pilot and a spotter? Now that's scary.... I do understand the use of UAV in hazardous areas, where there is enemy fire and/or risk of a pilot being captured. But why go to all the extra trouble just to police the border? |

How is see-and-avoid handled with unmanned weather balloons? Are they
only released in restricted airspace? Seems to me that there are some parallels with UAVs. |

Surely you can understand how a UAV and support team are much more efficient at going through taxpayer money than a 172. Perhaps it is another pork barrel project, or some company has friends in high places. Because, if they put out the ACTUAL job of searching for illegal crossings I would find it very hard to believe that it couldn't be done by a small fleet of properly equipped 172's or 182's and a reasonable staff of pilots and observers. Heck, why don't they try giving the job to CAP and see how well that concept works? |
