Learjet Tone

Recommended Posts

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.

How close are you to the mountain tops? Try cycling the gear and see if the tone stops. Could be the ground proximity alarm. IIRC if you are within 200ft with gear raised, it will sound off.

Been away for a while. It was the mountain tops in totally cloudy conditions. Thanks for the tip!
