Methods
aoaToNormAoa
▸ aoaToNormAoa(aoa): number
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
| Name | Type | Description |
|---|---|---|
aoa | number | An absolute angle of attack value, in degrees. |
Returns
number
The normalized equivalent of the specified angle of attack.

Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:197
destroy
▸ destroy(): void
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
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:307
estimateIasFromAoa
▸ estimateIasFromAoa(aoa): number
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
| Name | 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
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:209
estimateIasFromNormAoa
▸ estimateIasFromNormAoa(normAoa): number
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
| Name | 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.

init
▸ init(paused?): void
Initializes this data provider. Once initialized, this data provider will continuously update its data until paused or destroyed.
Parameters
| Name | 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.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:148
normAoaToAoa
▸ normAoaToAoa(normAoa): number
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
| Name | Type | Description |
|---|---|---|

Returns
number
The absolute equivalent of the specified normalized angle of attack, in degrees.

pause
▸ pause(): void
Pauses this data provider. Once paused, this data provider will not update its data until it is resumed.
Returns
void
Throws
Error if this data provider is dead.
Defined in
