Celestial navigation is not used anymore, nor even
teached or referred to, for air navigation, since the improved reliability of
the current nav instruments. We have, for long haul flights, inertials platform
(3), gps (2) and 3 flight computers cross checking all the data. I don't
know if the greater speed of late airliners could be a problem
for the celnav.
