This instrument shows how fast an aircraft is climbing or descending.

This instrument is a barometer that measures atmospheric air pressure. It is calibrated in feet instead of inches of mercury.

This instrument measures the difference between static pressure and ram air pressure. It is therefore a differential pressure gauge.

Pilots use this instrument to help them establish the correct rate of descent during approaches and to maintain steady rates of climb or decent.

The face of this instrument has colored markings that are critical for the pilot to understand.

If properly calibrated, this instrument will register zero in level flight.

This instrument must be set by the pilot to the current air pressure given by weather services or air traffic control.

.................................. or ambient air is the relatively undisturbed air surrounding the aircraft.

All three pitot static instruments are connected to a static .................................. , which introduces outside air into the case of each instrument.
