Altimetre Flashcards
1
Q
The formula to know QFE
A
QNH - (elevation/27)
2
Q
The formula to know PA or pressure altitude
A
Elevation + ((1013-QNH) x 27)
3
Q
QFE
A
Height, related to the aerodrome field
4
Q
QNH
A
Altitude, mean sea level
5
Q
QNE
A
Pressure altitude ISA, also related to temperature altitude like density and true altitude
6
Q
Formula for DA (density altitude)
A
PA + (ISA deviation x 120)
7
Q
Formula for DA (density altitude) in airfield
A
PA + ((abient temp - 15C) x 120)
8
Q
Calculate ISA deviation formula
A
15C - (2 x alt/1000)
9
Q
TA (True altitude) formula
A
QNH alt + T/E correction
TA = QNH alt + (4 x (HAS/1000) x ISA dev)
10
Q
TE (temperature error)
A
(4 x (HAS/1000) x ISA dev)
