This just points up the need to get a fully configurable autopilot running. If there isn't a DG you can't really follow heading. So the j3-cub should not even have an autopilot without it. As you know, the way the auto pilot ties in to the instrument with Curt's patch is the correct behavior.

A fully-configurable AP will be nice, because Norm will then be able to tie it to the true heading for his GIS work, while people who want flight simulation will have the option to make it behave realistically (tied to a DG on a small plane, or a complex FMS on a larger one).

If you lose an engine or have any sort of mechanical failure on a single side, you are going to hit hard at some really odd angle. At least with a helicopter you are probably going to land butt first and might have a chance to try an autorotation.

If you lose an engine or have any sort of mechanical failure on a single side, you are going to hit hard at some really odd angle. At least with a helicopter you are probably going to land butt first and might have a chance to try an autorotation. I would be very surprised if the engines are not cross-coupled such that each engine drives both props, as in the V-22. A single engine failure would not cause one rotor to be unpowered. The gearbox for the V-22 was one of the main design challenges for the Osprey, IIRC. The other components of the drive train/propulsion system are made for extremely high reliability for that very reason. They are mostly "Criticality 1" items. I agree that the big danger is at takeoff and landing, for sure, but it's because of the aero phenomena. I wonder if clever placement of sensors about the aircraft and some Expert Systems logic could potentially sense dangerous conditions and adapt appropriately?

I agree with the people who are saying this can be made to fly safely within reasonable tolerances, but I also think there are certain phases where it's probably always going to be a little less safe than a helicopter, or perhaps you could say that certain types of failures at certain times would be less survivable in the BA-609 ...

One thing that comes to my mind though, for V-22, is that survivability might be increased in one way due to less time spent in the combat area. You dash in fast, you drop down and pick up the downed airman, then you dash out fast. It's got the advantage over helicopters in that respect, at least. If the BA_609 proves to be as safe as helicopters I can see it really "taking off".
