Interface: AoaDataProvider

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:11

A provider of angle of attack data.

Properties​

aoa​

readonly aoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:13

The current angle of attack, in degrees.


isDataFailed​

readonly isDataFailed: Subscribable<boolean>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:35

Whether this provider's AoA data is in a failed state.


isOnGround​

readonly isOnGround: Subscribable<boolean>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:32

Whether the airplane is on the ground.


normAoa​

readonly normAoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:16

The current normalized angle of attack. A value of 0 is equal to zero-lift AoA, and a value of 1 is equal to stall AoA.


normAoaIasCoef​

readonly normAoaIasCoef: Subscribable<number | null>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:29

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.


stallAoa​

readonly stallAoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:19

The current stall (critical) angle of attack, in degrees.


zeroLiftAoa​

readonly zeroLiftAoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:22

The current zero-lift angle of attack, in degrees.

Methods​

aoaToNormAoa()​

aoaToNormAoa(aoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:43

Converts an absolute angle of attack value in degrees to a normalized angle of attack value. Normalized angle of attack is defined such that 0 equals zero-lift AoA, and 1 equals stall AoA.

Parameters​

ParameterTypeDescription
aoanumberAn absolute angle of attack value, in degrees.

Returns​

number

The normalized equivalent of the specified angle of attack.


estimateIasFromAoa()​

estimateIasFromAoa(aoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:60

Estimates the indicated airspeed, in knots, required to maintain level flight at a given angle of attack value for the current aircraft configuration and environment.

Parameters​

ParameterTypeDescription
aoanumberAn angle of attack value, in degrees.

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.


estimateIasFromNormAoa()​

estimateIasFromNormAoa(normAoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:70

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.


normAoaToAoa()​

normAoaToAoa(normAoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:51

Converts a normalized angle of attack value to an absolute angle of attack value in degrees. 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 absolute equivalent of the specified normalized angle of attack, in degrees.
