Quantity kinds in aerospace (TAS, CAS, geopotential altitude etc.)
Units and quantities common in aerospace engineering.
See: isqx._citations.ICAO
PRESSURE_ALTITUDE = ALTITUDE['pressure']
Pressure altitude, as measured by the altimeter.
DENSITY_ALTITUDE = ALTITUDE['density']
Density altitude, as measured by the altimeter.
GEOPOTENTIAL_ALTITUDE = ALTITUDE['geopotential']
Geopotential altitude, as measured from mean sea level.
GEOMETRIC_ALTITUDE = ALTITUDE['geometric']
Geometric altitude, as measured from mean sea level.
Geodetic height. See https://en.wikipedia.org/wiki/Geodetic_coordinates.
Height above ground level. Not to be confused with altitude.
CONST_TEMPERATURE_ISA: Annotated[
Decimal, STATIC_TEMPERATURE(K)
] = Decimal("288.15")
TEMPERATURE_DEVIATION_ISA = STATIC_TEMPERATURE[
DELTA, OriginAt(Quantity(CONST_TEMPERATURE_ISA, K))
]
Deviation from the ISA temperature at sea level.
IAS = AIRSPEED['indicated']
Indicated airspeed, as measured directly from the airspeed indicator.
CAS = AIRSPEED['calibrated']
Calibrated airspeed, IAS corrected for instrument and position errors.
Vertical speed, rate of climb or descent. Commonly expressed in feet per minute.
