December 7, 201411 yr Hello All-everything goes great with flight in the Learjet except for a persistent issue. During flight when the autopilot is on, out of curiosity I make the mistake of turning on the radar altimeter and testing it. All of a sudden a tone comes on. I'll turn the altimeter off, but the tone stays on. I start turning all switches on and off, but the tone stays on. It is so irritating that I stop the flight. Anyone know what I'm doing wrong? Thanks. Forever indebted to the late Michael Greenblatt of FSGS.
