Atmosphere Pressure Flashcards
what unit is The UK Atmospheric pressure is reported in?
hPa
The pressure setting that when set on an aircraft’s altimeter sub-scale would show the height of the aircraft above mean sea level at that airfield.
QNH
what setting is set if The fixed value pressure setting corresponding to the average atmospheric pressure at sea level
SAS
what setting is set if The forecast lowest QNH for an altimeter setting region valid for a period of one hour.
RPS
The pressure setting that when set on an aircraft’s altimeter sub-scale would show the height of the aircraft above the aerodrome.
QFE
The pressure setting which would indicate the airfield elevation if set on the altimeter subscale for an aircraft on the runway is the
QNH
Which altimeter setting would be used by pilots in the UK for flying routes across the country below the Transition Altitude?
RPS
If an aircraft is reporting their height according to ‘Flight Levels’, what altimeter setting are they using?
SAS
Assuming no change in the mass of air above a point, a reduction in air temperature would tend lead to…
A rise in pressure
pressure….. with increased altitude at an approximate rate of 1 hectopascal for every ……feet.
