I'm planing a way-point flight around cliffs. Say you take off on a cliff and it's 20 meters above the actual ground and you ascend 10 meters when you fly over the cliff will the bird register that the height has changed from 10 meters to 30 meters or will it still indicate 10 meters in the air? Need to know if i need to compensate when going up the cliff.
My head says it will not change because as i understand the barometer reads the pressure on the takeoff point and uses that as ground level and uses the change to calculate the birds altitude. I'm i right?
