I have this Radio Altimeter on my Dreamfleet Bonanza and I can't figure out what's it's for.
Anyone....

I do believe it is to tell you the distance between aircraft and the ground below you. Very practical in low vis situations.

I liken it to depth finder on a boat, where the signal gives you a positive distance between the sender and the ground. This is more accurate than the altimeter.

If it's so good, why is it not the default instead of the Altimeter cage.
Not arguing, just trying to figure it all out.

Using it as the default would be a bad thing...
To my way of thinking, especially in approach and departure scenarios, with crowded skies and aircraft climbing and descending, ATC and the pilots would want to maintain a CONSTANT altitude, not an arbitrary one based on what's below you at any given moment.
I believe the operative words in the link James posted is "ground and obstacle clearance". For maintaining vertical seperation of aircraft, barometric altimeters are more prefered.
Cheers!

I prefer to use both, Altimeter for flying at a given level, Radio altimeter for final and landing. Helicopters like to have that info while in a hover if your carrying cargo on a sling etc...
