Abstract Class: AutothrottleThrottle

Defined in: src/sdk/autothrottle/AbstractAutothrottle.ts:1700

A throttle controlled by an autothrottle system.

Constructors

Constructor

new AutothrottleThrottle(bus, info, servoSpeed, powerSmoothingConstant, powerSmoothingVelocityConstant, powerLookahead, powerLookaheadSmoothingConstant, powerLookaheadSmoothingVelocityConstant, throttleLeverManager?): AutothrottleThrottle

Defined in: src/sdk/autothrottle/AbstractAutothrottle.ts:1792

Constructor.

Parameters

Parameter	Type	Description
bus	EventBus	The event bus.
info	AutothrottleThrottleInfo	Information describing this throttle.
servoSpeed	number | Accessible<number>	The speed delivered by the servo controlling this throttle, in units of normalized position per second.
powerSmoothingConstant	number	The smoothing time constant, in seconds, to use to smooth engine power data.
powerSmoothingVelocityConstant	undefined | number	The smoothing time constant, in seconds, to use to smooth estimated power velocity while smoothing engine power data. A value of zero is equivalent to no smoothing. If not defined, estimated power velocity will not be used to adjust smoothed engine power data.
powerLookahead	Subscribable<number>	The lookahead time, in seconds, to use for engine power data.
powerLookaheadSmoothingConstant	undefined | number	The smoothing time constant, in seconds, to use to smooth lookahead engine power data. If not defined, defaults to the value of powerSmoothingConstant.
powerLookaheadSmoothingVelocityConstant	undefined | number	The smoothing time constant, in seconds, to use to smooth estimated power velocity while smoothing lookahead engine power data. A value of zero is equivalent to no smoothing. If not defined, estimated power velocity will not be used to adjust smoothed lookahead engine power data. If not defined, defaults to the value of powerSmoothingVelocityConstant.
throttleLeverManager?	ThrottleLeverManager	The throttle lever manager to use to request position changes for this throttle's lever. If not defined, position changes for the lever will be requested using key events (specifically the THROTTLE[N]_SET event).
