hlink.net... "Tony Cox" wrote in message nk.net... Indeed. But it makes it *more dangerous*, which is why Larry's post is relevant, even if UAV's are supposedly confined to Class A airspace. It makes it *more dangerous* only in the sense that more traffic makes flying more dangerous. Any aircraft can have a mechanical failure that affects it's ability to maintain altitude and/or maneuver. It's not *more dangerous* simply because it's a UAV. It is if the pilot can't scan for traffic or search for a suitable emergency landing site. In any case, an aircraft "in distress" is only allowed to violate the FAR's as far as necessary to deal with the emergency. I'd have a hard time proving reasonable violation of "See and Avoid" in the simple case of engine failure. You're proposing that these UAV's can simply ignore this rule because they're supposed to be in class A all the time. |

This test facility is not in a restricted area. http://www.dfrc.nasa.gov/Gallery/Pho...03-0078-1.html ....and as copied from: http://www.defense-aerospace.com/cgi...9&modele=jdc_1 "Altair is expected to be the first UAV to meet Federal Aviation Administration requirements to operate from conventional airports, with piloted aircraft, in the national airspace. In addition to triple-redundant avionics, Altair is configured with a fault-tolerant, dual-architecture flight control system. The UAV will be equipped with an automated collision-avoidance system and an air traffic control voice relay. The relay allows air-traffic controllers to talk to ground-based Altair pilots through the aircraft." On several occasions, Joshua Control has called me with warnings about UAVs and their chase planes orbiting around El Mirage Dry Lake. The location is a couple miles north of KREY near Adelanto, California. |

A lot of good that will do you when the military doesn't inform civilian authorities and thus you have no idea an unmanned drone is rapidly descending on you. They're not drones. There is no way unmanned aircraft can mix with all others and not have some reduction in safety. The questions are just how much of a reduction, what can be done to mitigate the danger, and regulations which do not penalize GA pilots for being in the wrong place at the wrong time. If operations are confined to Restricted Areas and Class A airspace they're not mixing with all others. Their operations are not confined to restricted areas and Class A airspace. |

Will there be new Restricted Areas imposed along the border, or will the UAVs be flown in Positive Control Airspace? It's not just the military, but civilian government agencies that are considering the use of UAV's. The AvFlash article mentioned the Border Patrol UAVs being operated by the military. If the UAV's are in the flight levels, then they will be in Positive Control Airspace, right? That might be true if they are capable of adequate surveillance performance from 18,000' MSL, but they will have to climb to that altitude outside Positive Control Airspace, in Joint Use airspace or Restricted airspace, as the NAS is currently structured. If the UAV's are for border patrol, would it not be reasonable to expect them to be within a few miles of the border? As such, how much of an issue would you expect them to be to Part 91 flights? Or are you concerned about the occassional drug-running flight? ![]() While the UAVs may operate within a few miles of the national boarders, I doubt they will be based there. So it is likely they will have to traverse Joint Use airspace en route to their stations. As for your question border restricted areas, I have to question how many Part 91 flights are conducted close enough to the border for this to be a problem. Do you know how many occur in any given time frame? Many international Part 91 flights occur each day. 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. UAV use in general airspace should be carefully considered before implementation, but I'm not as concerned about their use in border patrol use as I am about their loitering over a city with several nearby airports and busy airspace. And how long do you estimate it will take for UAVs to be operating beyond the national boarder corridors, given the national hysteria? As for your subject line question, I'd wait for an NTSB ruling before passing judgment on that. Right. It's difficult to generalize about potential MAC responsibility without specific facts. However, once the inevitable MAC occurs, and the Part 91 pilot is no longer able to testify (due to his untimely death), do you expect the team operating the UAV to actually take responsibility for their failure to see-and-avoid? From the past behavior of military in MACs with civil aircraft, I would expect the military to deny all responsibility. This begs the question, how is the UAV's conspicuity planned to be enhanced? |

A mechanical failure would make it an aircraft in distress. An aircraft
in distress has the right-of-way over all other air traffic. Under the existing definition, sure--but this definition presupposes that such an aircraft has human occupants. To my thinking, unmanned hardware can't exactly experience "distress"; therefore, right-of-way shouldn't be an absolute in this instance. Manned air traffic should never be jeopardized by unmanned aircraft, irrespective of any malfunction such hardware may experience. "Safety" always pertains to the human element, never machinery. A related thought: rockets always have a human-controlled self-destruct capability to protect lives and property on the ground should the vehicle experience a loss of control. Maybe UAVs should have this cabability too. |

Did you read the entire content of my article? You'll note in one of the excerpts of the links, that the demonstration UAV was at 200' AGL. There is no altitude reference outside of Class A airspace, so presumably see-and-avoid is not an issue. Agreed; your assessment is presumptuous. Yeah, they've got to climb through Class E airspace to get to Class A, but I'd assume that'll be done in a restricted area. From the links I provided in the article, it seems that the FARs are being revised to accommodate UAVs outside of restricted airspace. |

Will there be new Restricted Areas imposed along the border, or will the UAVs be flown in Positive Control Airspace? Good question. In fact, several good questions. As for "see-and-avoid", there is some visual feedback to the remote pilot ahead. I've no idea as to the quality of the circuit, nor the coverage of the sky from the cockpit it gives the pilot. If the quality is sufficient that the remote pilot can pass the aviation medical eye exam over the remote circuit (put the eye chart in front of the plane and ask the remote pilot what the letters say, color charts, etc.), I don't see the problem ;-) That would be a reasonable test of the UAV pilots' ability to comply with the see-and-avoid regulation, but the UAV pilots would have to be able to see above and below and to the sides in addition to airspace immediately ahead. 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 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? |

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. 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 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? 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. |

ws.com: What's the problem if it's restricted space? None, if it's restricted airspace. But it may very well be in joint use airspace, especially if the other civilian players get into the game. They'll be climbing through the Cessnas flying around. Many international Part 91 flights occur each day. So the answer to my yes/no question would be...? No, you don't know. I can't give you an exact number, but it's in the thousands. There are thousands of daily helicopter flights to/from the Gulf of Mexico alone, nevermind the true international flights, both airline and Part 135 and Part 91 flights, US and other countries. My best guess is that it's in the tens of thousands daily, counting everything. We're giving up lots of freedoms to the government, and now we're expected to possibly give our lives, for little or no return. The sky is falling, the sky is falling!!!! Not I, said the little red hen. -- Regards, Stan |
