Altimetry Flashcards
What is QFE?
FIELD DATUM PRESSURE;
Altimeter set to READ off GROUND
What is QNE?
STANDARD altimeter setting of 1013.25HPa
What is QNH?
STATION PRESSURE reduced to SEA LEVEL per ISA;
Altimeter will read AERODROME ELEVATION
What is altitude?
HEIGHT AMSL or a SPECIFIED DATUM
What is elevation?
The HEIGHT in AMSL the GROUND lies ABOVE the MSL
What is flight level?
The HEIGHT of AIRCRAFT above the 1013.25HPa DATUM
What is the pressure datum?
The PRESSURE that CORRESPONDS to a particular LEVEL in the ATMOSPHERE
What is the pressure sub scale?
ADJUSTING the altimeter BASED off a PRESSURE DATUM;
When PRESSURE SCALE INCREASES, INDICATED ALTITUDE INCREASES
What is the pressure height?
Th HEIGHT assigned to a GIVEN BAROMETRIC PRESSURE in IAS CONDITIONS
What is density altitude?
How can it be found?
An ATMOSPHERE EXPRESSED IN terms of HEIGHT which corresponds to that DENSITY at ISA CONDITIONS;
PRESSURE ALTITUDE CORRECTED for TEMPERATURE DEVIATIONS;
CALCULATION, P-CHART, NAV COMPUTER
