Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:26
The correlation coefficient between a given normalized angle of attack and the estimated indicated airspeed in
knots required to maintain level flight at that angle of attack for the current aircraft configuration and
environment, or null
if such a value cannot be calculated.

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:19
The current conversion factor from true airspeed to indicated airspeed.
Methods
estimateIasFromNormAoa()
estimateIasFromNormAoa(
normAoa
):number
Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:36
Estimates the indicated airspeed, in knots, required to maintain level flight at a given normalized angle of
attack value for the current aircraft configuration and environment. Normalized angle of attack is defined such
that 0
equals zero-lift AoA, and 1
equals stall AoA.
Parameters
Parameter | Type | Description |
---|---|---|
normAoa | number | A normalized angle of attack value. |
Returns
number
The estimated indicated airspeed, in knots, required to maintain level flight at the specified angle of
attack, or NaN
if an estimate cannot be made.
