PITOT AND STATIC PRESSURE SOURCES Flashcards
1
Q
A pitot head is used to measure:
A
static plus dynamic pressure
2
Q
A static vent is used to measure:
A
atmospheric pressure.
3
Q
A pressure head is subject to the following errors:
A
position, manoeuvre-induced, instrument.
4
Q
Given:
Pt = total pressure
Ps = static pressure Dynamic pressure is:
A
Pt – Ps
5
Q
Manoeuvre induced error:
A
is caused by transient pressure changes at static vents.
6
Q
Position error:
A
may be reduced by the fitting of static vents
7
Q
Fitting static vents to both sides of the aircraft fuselage will:
A
balance out errors caused by side slipping or yawing
8
Q
Where an alternate static source is fitted, use of this source usually leads to:
A
an increase in position error
