TD24 Flashcards
In the event of an electrical failure, the ENG A/I start/bleed valves are going to revert to the ______ mode. How much Q could be lost from MTA and what advisory activates?
The engine anti-ice/deice system is designed so that in the event of an electrical failure the valve reverts to the antiicing mode and activates the ENG 1 ANTI-ICE ON or ENG 2 ANTI-ICE ON advisory. 20% Q from MTA.
Operating an engine against the _____ _____ is prohibited on rotor brake equipped helicopters. When using the rotor brake before starting engines, the minimum pressure will be 450 psi. If inadvertent rotor blade movement should occur due to rotor brake slippage, immediately_________ _________ engine(s) or _______ _______ _______. During engine run-up, for rotor brake operations, ensure that approximately 45% NR for single engine operations and 57% NR for dual engine is reached prior to advancing PCLs to fly.
Gust lock, shut down , release rotor brake
Discuss the safety devices, limitations, and emergency procedures for the rotor brake.
The Interlock prevents moving EPCL(s) past idle when engaged unless Tab is manually pulled. Max NR is 76% for Emer. Rotor Brake application., Routine stops 40% NR with 150-180 psi for not less than 12 Seconds, Rotor Brake for ENG Start Min-450 and Max-690 psi.
Where are the cold start capsule lights located? What indications do they provide?
Located on the upper console. Emer Cargo Release test light, Batt Good, Batt Low, APU ON, ACC LOW, (apu) OIL HOT, APU FAIL
How long must a CAUTION be displayed before the pilot is able to acknowledge the caution?
The caution must be displayed for atleast 2 seconds before having the ability to acknowledge.
What are the three annunciators on the top of the FMS and what do they indicate?
STS- Change in system status FMS- BIT Fail within the FMS MSG- Active, reserved for further use
How is the EMER SE-IAS (Item 15) derived from the PPC? When do I have to use this EMER SE-IAS and must I have one or two EMER SE-IAS’s?
Selected from the MIN/MAX-IAS (single engine) range computed in item 29. It is used immediately following an EP that requires Establishing S-E A/S. Normally only one is selected but two may be selected when item 29 is a wide range. 1-Slow and 1-Fast based on mission profile.
What is “blowback” and what pilot action is required to compensate for it?
Blowback is the rearward tilt of the rotor disk. The Pilot moves the cyclic (cyclic feathering) forward as velocity of the helicopter increases.
