This strikes me as correct behavior. If you stick a pitot tube
into an airstream backwards, you will get exactly the same
reading as forward (well, modulo viscosity and mach effects). If

I implemented a radar doppler based drift indicator already a few weeks
ago, thanks. But we are speaking about a display error in the ASI.

So, as you didn't bother to write a whole sentence and leave the
interpretation to the reader, which I find quite annoying, is it
the following what you are trying to say: YASim is right, (airspeed-kt)

Seems that there are two bugs that make the bo105 ASI show
positive speeds when flying backwards:
1. YASim delivers a positive "/velocities/airspeed-kt" on backward
flight.
2. Systems/pitot.cxx wouldn't handle negative values correctly,
anyway, as it squares the speed without checking for n
