Type Alias: AirspeedDefinitionContext

AirspeedDefinitionContext = object

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:8

A context for a AirspeedDefinitionFactory.

Properties​

bus​

readonly bus: EventBus

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:10

The event bus.


machToKias​

readonly machToKias: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:16

The current conversion factor from mach number to knots indicated airspeed.


normAoaIasCoef​

readonly normAoaIasCoef: 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​

readonly pressureAlt: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/airspeed/AirspeedDefinitionFactory.ts:13

The current pressure altitude, in feet.


tasToIas​

readonly tasToIas: 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​

ParameterTypeDescription
normAoanumberA 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.
