Prefix meaning "high"

Usage examples of alti.

Instead of waiting to feel the pull of the AOD on the pin, I kept on looking at the alti, and bang on 30,000 feet I pulled the handle and pushed my hands up above my head, which made me backslide, which meant the air would catch the drogue chute to bring the main pack out.

After about ten minutes I checked my alti again: 6,500 feet, time to start working.
