Fuel Metering
High atmospheric humidity has this effect on the operation of a turbine engine?
What is little or no effect?
The ignition system of a gas turbine engine differs from that of a reciprocating engine because it requires this type of spark for ignition.
What is a high-energy spark?
What type of oil system is usually found on turbine engines?
Dry sump, pressure, and spray.
The engine should face this direction prior to performing engine trimming.
What is into the wind?
High power-to-weight ratio is the primary advantage of this type of starter over others?
What is a pneumatic (air turbine) starter?
The recommended aircraft engine lubricants are
Mineral or synthetic based.
This publication is used for guidance to determine whether a powerplant repair is major or minor?
What is 14 CFR part 43, Appendix A?
This component splits the fuel into primary and secondary fuel flow.
What is the Flow Divider?
Airflow to the pneumatic starter from a ground unit is normally prevented from causing starter over-speed during engine start by this component.
What is the flyweight cutout switch?
In order to relieve excessive pump pressure in an engine's internal oil system, most engines are equipped with a
relief valve.
What publication contains the mandatory replacement time for parts of a turbine engine?
Engine Manufacturer's service instructions.
An engine control system that receives all the necessary data for engine operation and develops and sends commands to the engine electronically is known as this acronym.
What is FADEC? (Full Authority Digital Engine Control)
These components used in turbine engines have a longer service life because they do not require continuous operation.
What are igniter plugs?
This marker indicates the area not to be when working near the engine during engine runup.
What is the red line on the cowling?
What is the purpose of the last chance oil filters?
To filter the oil immediately before it enters the main bearings.
When must an Airworthiness Directive (AD) be complied with after it becomes effective?
As specified in the AD.
Ensuring turbine blade to engine case clearances are kept to a minimum by controlling case temperatures is known as this acronym.
What is ACC or Active Clearance Control?
The igniter lead is disconnected from the plug and the center electrode grounded to the engine to minimize the possibility of this.
What is the technician receiving a lethal shock?
This component in a starter-generator circuit opens to disconnect power from the starter windings and ignition when sufficient engine speed is reached.
What is the under current relay?
Why are fixed orifice nozzles used in the lubrication system of gas turbine engines?
To provide a relatively constant oil flow to the main bearings at all engine speeds.
