DA 62 AFM General
QNH: Theoretical atmospheric pressure at MSL, calculated from the elevation
of the of the measuring point above MSL, and the actual atmospheric
pressure at the measuring point.
Density Altitude:
Altitude in ISA conditions at which the air density is equal to the current
air density.
Indicated Pressure Altitude:
Altitude reading with altimeter set to 1013.25 hPa (29.92 inHg).
Pressure Altitude:
Altitude indicated by a barometric altimeter, which is set to 1013.25 hPa
(29.92 inHg). The Pressure Altitude is the Indicated Pressure Altitude
corrected for installation and instrument errors.
In this Airplane Flight Manual, altimeter instrument errors are regarded
as zero.
Wind: The wind speeds which are shown as variables in the diagrams and
tables in this manual should be regarded as headwind or tailwind
components of the measured wind.
(c) Flight Performance and Flight Planning
AGL: Above Ground Level.
Demonstrated Crosswind Component:
The speed of the crosswind component at which adequate
maneuverability for take-off and landing has been demonstrated during
type certification.
