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.
