Pitot-Static Systems

Question 1

The _______ system consists of PNEUMATIC LINES that TRANSMIT air pressures to various instruments (diagram in a moment)

Answer 1

Pitot-static system

Question 2

Altimeter

Vertical Speed Indicator

Airspeed indicator

Answer 2

3 main instruments that use the pitot-static system of the aircraft

Question 3

______ pressure generated by the motion of the aircraft through the air (impact pressure)

Also referred to as RAM air pressure or total pressure

Pitot pressure is collected by the forward opening on pitot probe.

probe is coupled to VSI via tubing

Answer 3

Pitot pressure

Question 4

______ –> stationary or not changing

Pressure due to the stationary air through which the aircraft is flying (i.e. atmospheric pressure)

Collected by static ports on the side of the aircraft fuselage

transmitted to instruments (ASI, VSI, ALT) via tubing.

Answer 4

Static Pressure

Question 5

_______ test is to see if quick changes in descending altitudes will be the same at the same pressure level as they were for ascending altitudes. (Tests the elasticity of the aneroid)

Answer 5

Hysteresis test

Question 6

A _______ is used to compensate for the difference in the pressure throughout the duration of the flight.

For example, the pressure at sea level at one location can change throughout the day.

Answer 6

baro set knob

Question 7

When performing a pitot leak test on unpressurized aircraft, we are allowed to lose _______ ft./min of air when the system is closed up.

Answer 7

100 ft./min

Question 8

This ALLOWS for a tighter vertical separation of 1000 ft. as opposed to 2000 ft. RVSM is required for aircraft flying above 29 000 ft.

Answer 8

The ‘RVSM’ certification stands for Reduced Vertical Separation Minimums
