'''Absolute''' altitude is how high you actually are above ''mean sea level'' ('''MSL'''). Go to the beach, and there is your "absolute level", no mountains in the way, you can fly across the ocean at around 200ft if wanted and this is important height "measurment", mainly for avoiding terrain and obstacles (underwater). | '''Absolute''' altitude is how high you actually are above ''mean sea level'' ('''MSL''').
