L'aviator
L'aviator - Indeed, I agree wholeheartedly, as per my OP:
"situations can and do develop very quickly and need quick and accurate resolution in a predictable fashion according to the IRPCS ColRegs so it is an invaluable safety tool (with limitations granted) but is an excellent aid to situational awareness and pilotage planning. Mk.1 eyeball still takes precedence however, with AIS (and radar) a good backup."
