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?
These are the three main types of starters found on turbine engines today.
What are electric motor, air turbine, or starter generator?
One of these two types of oil systems are usually found on turbine engines.
What is Dry sump or Wet Sump?
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?
This telltale sound can be used to operationally check the ignitors while they are installed in the engine.
What is a loud "click"? DAILY DOUBLE
In order to prevent excessive pump pressure in an engine's internal oil system, most engines are equipped with this.
What is a relief valve? DAILY DOUBLE
What publication contains the mandatory replacement time for parts of a turbine engine?
What are the 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 for ignition 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 while it is running.
What is forward of the red line on the cowling?
The purpose of a last chance oil filter is to remove fine particles before they reach this critical component.
What is the bearing?
When must an Airworthiness Directive (AD) be complied with after it becomes effective?
What is 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?
To provide a relatively constant oil flow to the main bearings at all engine speeds, these type of nozzles are used.
What are fixed orifice nozzles?
The Wright Brothers made their first controlled, powered flight on this date.
What is December 17, 1903?
