help me to understand IMC flying
On another place, in a thread about the unfortunate pilot who crashed near to the M40 yesterday, some of the responders have mentioned "FAA PTS limits are 3/4 scale deflection and +/- 10kts" wrt the conditions yesterday. Can someone explain, for me as a NPPL(M) nice weather pilot, what is the "scale deflection"? It sounds like a reading of some sort of gauge.
