radalt and weight on wheels

I'm not an RA expert, but on many aircraft the "Weight on wheels" discrete (boolean) is broadcast to almost all avionics. A simple enhancement might be if the RA notices negative or very low height...

BOAC: whether there was the intention to autoland or not (and I agree, I doubt they would be able to engage the full CAT III) they had the AP following the glide and loc and the AT engaged and with...

routine use of autoland

fox niner: originally, the idea of using autoland in all possible circumstances was to get maximum experience with, and reliability statistics on autoland eliability. Tragically ironic in this case,...
