A pressure altimeter is an instrument that measures the outside air pressure, and then uses this pressure reading to estimate the height. Suppose Captain Bob flies at fixed pressure altimeter reading (which really means he's flying at constant pressure) into an upper-level trough. The actual height of Bob's plane would then likely_____.

Answer:

Increase

Step-by-step explanation:

A pressure altimeter is an instrument that measures the outside air pressure, and then uses this pressure reading to estimate the height. If Captain Bob flies at fixed pressure altimeter reading (which really means he's flying at constant pressure) into an upper-level trough. The actual height of Captain Bob's plane would then likely increase because he's flying at constant pressure.
