15.13 Flashcards
What are the three main engine controls
Engine start
Forward Thrust
Reverse Thrust
What would happen if you drop an igniter plug
The insulator can break
What can the starting system for a gas turbine engine be
Pneumatic or electric
What three positions does the reverse thrust lever have
Normal ( stow the reverser) Reverse idle (activate the reverser) Full reverser ( increase engine power)
How are the throttle control system kept in the selected position
Use of friction break
How many resolvers are there for each thrust control lever
2
What does the starter motor do
Operate engine compressor
What components are needed to generate high energy sparks in the ignition system
Ignition exciter ( generate high voltage)
Igniter plug ( produces the spark)
Ignition lead
Electrical power and switches
What does the starter lever do?
Switch fuel on/off and switch ignition on during engine start
What are forward thrust levers also called
Throttle
What does the thrust lock system do
Prevents the forward thrust and the reverse thrust from being activated together
What does the forward thrust lever do
Control the thrust of engine between idle and take-off
What is the insulator made of for igniter plugs with two blue rings
Beryllium oxide (toxic)
What does the ceramic insulator do to the centre contact of the ignition lead
Holds it centred
What does a resolver do
Electrical component that converts angular deflection of the input lever to an electrical signal
