I meant bottom of my boots - i.e. my gear. When the "fifty" is called doesn't that mean my gear is 50 ft off the ground? Me sitting 15 ft higher is then 65ish ft up in the air.
I don't think so...
Also, 737 radio altimeters do not usually read '0' on the ground. The readings I've seen (in data) are in the -4 to -2 range.
The radio altimeter antennae are located just behind the EE-bay access door. The #2 RA Transmitter is first, then the #2 RA receiver, then the #1's in the same order.
