Radar altimeter; What is it?
Posted: Wed Mar 05, 2003 3:01 amCould someone please tell me what the radar altimeter gauge is and how to use it? The gauge is on the great Baron 58 panel made by Tipster. I have no idea what that gauge is for...

Posted: Wed Mar 05, 2003 3:20 amJust to expand a little, your ordinary altimeter shows your distance above sea level based on the barometric pressure in the air.
The Radar altimeter takes no notice of air pressure, and simply sends a reflecting signal downwards (hence the `radar` element).
It will show your actual distance above the ground, rather than above sea level when in close enough proximity to it.
