Interface: AoaDataProvider
A provider of angle of attack data.
Implemented by
Properties
aoa
• Readonly aoa: Subscribable<number>
The current angle of attack, in degrees.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:13
isDataFailed
• Readonly isDataFailed: Subscribable<boolean>
Whether this provider's AoA data is in a failed state.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:35
isOnGround
• Readonly isOnGround: Subscribable<boolean>
Whether the airplane is on the ground.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:32
normAoa
• Readonly normAoa: Subscribable<number>
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.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:16
normAoaIasCoef
• Readonly normAoaIasCoef: Subscribable<null | number>
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.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:29
stallAoa
• Readonly stallAoa: Subscribable<number>
The current stall (critical) angle of attack, in degrees.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:19
zeroLiftAoa
• Readonly zeroLiftAoa: Subscribable<number>
The current zero-lift angle of attack, in degrees.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:22
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:43
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.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:60
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.
Defined in
src/garminsdk/components/nextgenpfd/aoa/AoaDataProvider.ts:70
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 |
|---|---|---|
normAoa | number | A normalized angle of attack value. |
Returns
number
The absolute equivalent of the specified normalized angle of attack, in degrees.
