Methods

estimateIasFromNormAoa()

estimateIasFromNormAoa(normAoa): number

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedIndicatorDataProvider.ts:88

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.
