Pitot And Static Sources Flashcards
1
Q
What instruments use static pressure only
A
Altimeter and VSI
2
Q
What instruments use pitot pressure only
A
ASI and Machmeter
3
Q
Pitot Tube is parallel to which axis of a/c
A
Parallel to longitudinal axis and airflow
4
Q
Pitot Tube must be positioned where?
A
Outside boundary layer
5
Q
Static port Must be at what angles
A
Right angles
6
Q
Duplication of static ports reduces what?
A
Reduces errors due to side slipping and yawing
7
Q
When is the Pressure-Position error max?
A
Max at low airspeed and high angle of attack
8
Q
Why is Maneuver-induced error caused? and when will it be max?
A
short-term fluctuations and delays in transmissions, start to climb or descent
9
Q
Why are drain holes fitted into pitot?
A
to drain the water, it will slightly affect the pressure.
