Other Systems Flashcards
Other systems
2 systems that require suction
De-icing boots
Standby artificial horizon
Other systems
Timing cycle for de-icing
6 seconds wings
6 seconds tail
168 seconds off
Other systems
Timing cycles for power plant anti ice
Fast 45 seconds on 135 seconds off
Slow 90 seconds on 90 seconds off
Other systems
When does the Standby compass read accurately
Turn off Pitot heat and stall warner Nav 1 Com 1 ADF Beacon Both generators
Other systems
RPM setting for icing
Max RPM
Other systems
What temp does the duct overheat switch cut off fuel to the heater
150°c
Other systems
How much fuel and from which tank does the heater draw
0.75 USG/hr delivered at 100psi +/- 1 psi
Starboard
Other systems
What is the temperature restriction for using F35
At our below 4°c it must contain FSII
Other systems
What temperature must the TGT be below prior to start
TGT must be below 150°c
Other systems
Prior to start you check the OAT, how does this affect the start sequence
Above 7°c OAT the condition levers should be advanced at 15%, down to -18°c it’s 13% and below -18°c it’s 12%
Other systems
Why do we check the battery voltage prior to start
To prevent a failed or hot start
24v
A weak battery may not have the power to ignite fuel efficiently and so by the time it does ignite there is more fuel than required
Other systems
What are the TGT parameters during start
810°c to 927°c for no more than 10 seconds
927°c for no more than 1 second
Other systems
How can you cool the engine
Run the starter motor with the igniters off.
Maximum 40seconds
Other systems
What are the timing constraints associated with the intentional shutdown of an engine
A restart must be conducted within 1 minutes per after 10 minutes
Other systems
What are the timing constraints associated with the operation of the starter motor
Engaged for no more than 40 seconds with a 1 minutes cool down period between the first 3 attempts after which it must be left to cool for 30 minutes
