VFR only pilots who venture into clouds can end up in one of these fairly easily. The end is when they notice the altitude decreasing quickly, and attempt to pull the nose up with the elevator. Unfortunately, the lift vector has to pull 5.8 Gs in order to keep level, because of the unnoticed 80 degree bank... this will occasionally pull off the tail, causing the pilot to have a bad day. > This is all nit picking though. > > Regards, > > Gordon Williams > > -- > http://www.piclist.com hint: The list server can filter out subtopics > (like ads or off topics) for you.
