40
Determine altitude by measuring air pressure.
Barometric Altimeter
41
In Barometric, As altitude increases, air pressure ______?
Decreases
42
What type of an Altimeter that sends a radio or laser signal toward the surface and measure the time it takes for the signal to bounce back?
Radio Altimeter (Radar Altimeter)
43
Determine altitude by using satellites to calculate altitude.
GNSS Altimeter
