normAoaIasCoef

readonly normAoaIasCoef: Subscribable<null | number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:105

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.

Implementation of

AoaDataProvider.normAoaIasCoef

stallAoa

readonly stallAoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:89

zeroLiftAoa

readonly zeroLiftAoa: Subscribable<number>

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:93

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

Implementation of

Methods

aoaToNormAoa()

aoaToNormAoa(aoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:197

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

Parameter	Type	Description
aoa	number	An absolute angle of attack value, in degrees.

Returns

number

The normalized equivalent of the specified angle of attack.

Implementation of

AoaDataProvider.aoaToNormAoa

---

destroy()

destroy(): void

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:311

Destroys this data provider. Once destroyed, this data provider will no longer update its provided data, and can no longer be paused or resumed.

Returns

void

---

estimateIasFromAoa()

estimateIasFromAoa(aoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:209

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

Parameter	Type	Description
aoa	number	An 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.

Implementation of

AoaDataProvider.estimateIasFromAoa

---

estimateIasFromNormAoa()

estimateIasFromNormAoa(normAoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:214

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.

Implementation of

AoaDataProvider.estimateIasFromNormAoa

---

init()

init(paused): void

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:148

Initializes this data provider. Once initialized, this data provider will continuously update its data until paused or destroyed.

Parameters

Parameter	Type	Default value	Description
paused	boolean	false	Whether to initialize this data provider as paused. If true, this data provider will provide an initial set of data but will not update the provided data until it is resumed. Defaults to false.

Returns

void

Throws

Error if this data provider is dead.

---

normAoaToAoa()

normAoaToAoa(normAoa): number

Defined in: src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:203

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
