Type Alias: AirspeedDefinitionContext
AirspeedDefinitionContext =
object
Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:8
A context for a AirspeedDefinitionFactory.
Properties
bus
readonlybus:EventBus
Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:10
The event bus.
machToKias
readonlymachToKias:Subscribable<number>
Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:16
The current conversion factor from mach number to knots indicated airspeed.
normAoaIasCoef
readonlynormAoaIasCoef:Subscribable<number|null>
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.
pressureAlt
readonlypressureAlt:Subscribable<number>
Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:13
The current pressure altitude, in feet.
tasToIas
readonlytasToIas:Subscribable<number>
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.
