Problem Altitude not Correct
The altitude number is not accurate. the altitube of the OSD is based on the GPS signal, which is good at ground positioning but not altitude (or height). The more satellite signal received, it will be more accurate. It become worst when the satellites is weak. like if there are only 4 or 5 satellite signal received. the error could be +- 20 meter.
if you need accurate altitude, you have to use atmospheric pressure meter
