Class: AglSystem

Defined in: src/garminsdk/system/AglSystem.ts:125

A Garmin system that calculates data related to the airplane's above ground height/level. The system supports sourcing FMS position data (plus terrain database) or radar altitude data.

Requires the event bus topics defined in ClockEvents to be published. In order to source FMS position data, requires the event bus topics defined in GNSSEvents and FmsPositionSystemEvents to be published. In order to source radar altitude data, requires the event bus topics defined in RadarAltimeterSystemEvents to be published.

Constructors

Constructor

new AglSystem(index, bus, powerSource?, options?): AglSystem

Defined in: src/garminsdk/system/AglSystem.ts:182

Creates an instance of an angle of attack computer system.

Parameters

Parameter	Type	Description
index	number	The index of the AoA computer.
bus	EventBus	An instance of the event bus.
powerSource?	CompositeLogicXMLElement | Subscribable<boolean> | keyof BaseElectricalEvents | `elec_bus_main_v_${number}` | `elec_bus_main_a_${number}` | `elec_master_battery_${number}` | `elec_circuit_avionics_on_${number}` | `elec_bat_v_${number}` | `elec_bat_a_${number}` | `elec_ext_power_available_${number}` | `elec_ext_power_on_${number}` | `elec_apu_gen_active_${number}` | `elec_apu_gen_switch_${number}` | `elec_eng_gen_switch_${number}` | `elec_circuit_on_${number}` | `elec_circuit_switch_on_${number}` | `elec_circuit_com_on_${number}` | `elec_circuit_nav_on_${number}`	The source from which to retrieve the system's power state. Can be an event bus topic defined in ElectricalEvents with boolean-valued data, an XML logic element that evaluates to zero (false) or non-zero (true) values, or a boolean-valued subscribable. If not defined, then the system will be considered always powered on.
options?	Readonly<AglSystemOptions>	Options with which to configure the system.
