The GPS has several modes optimised for different use cases. The default one 
is suitable for ground-based vehicles, and sanity checks its output including 
speed and altitude. In a plane you are at insane speed and altitude for a 
ground vehicle ;-) I don't think ogpsd has an option to change this, so a 
feature request may be in order.
