Mark, Kirk,
Many thanks for the information on Predator and Reaper UAVs. It's nice to know that those flying near the national border with a PCAS have a chance to detect and avoid one of these UAVs. Do either of you (or anyone else) know anything about the family of smaller, lighter UAVs that are being proposed for use by the Forest Service and others for detecting pot fields and forest fires? Do these also carry transponders? If the "big boys" don't comply with see and avoid, I assume there's no chance these little guys will, either. My concern is an encounter with a small UAV while running along the Appalachian ridges. -John Ferstlesque wrote: All Predators and Reapers have transponders with mode C, and maintain 2-way radio communication with ATC (with a phone as backup). Military Predators and Reapers do all of their training within Restricted airspace; when they must transit the national airspace to travel to their operating areas, they do so under an IFR flight plan above FL 180. They cannot "see and avoid" in the common sense of the phrase, so VFR flight in the NAS is not done. Kirk's estimates on weight are fairly accurate. Customs Predator B's have to be flown with a manned aircraft chase plane at all times in order to meet "see and avoid" criteria, and do so both inside and outside class A airspace. To me, this is the epitome of waste (defeats the purpose of UAV's and is well over twice the cost of a single aircraft with a sensor ball, AKA MC-12)... not to mention the several-fold increased risk of midair with the aircraft flying chase. I digress. Losing an aircraft in other than landing or takeoff is increasingly rare. If the signal is lost between the UAV and operator, it will fly back into the vacinity of the home airfield on a pre-programmed, pre- coordinated route. I can't speak for other UAV's, but the Predator family does not warrant the scepticism levied by the masses. Though I can understand where it's coming from. UAV's are a new concept, and very little is publicly released. I flew the Predator for 5 years and have a close friend who chases Predators around with customs. If anyone has any other BASIC questions about their operation with regard to the NAS and manned aircraft, please ask. Mark |
