" Unless I'm mistaken, I believe that you need to have an "official" clock
in the plane to fly actual. Doesn't mean that you have to use it, but I
believe it has to be there and has to be working. We are replacing ours
right now. (Seems like a silly reg.)


A clock and a timer can serve two different purposes. A timer is useful for
timing hold legs, but the clock is needed to determine when you can descend
in a lost comm situation.
