TD15 Flashcards
List the three times the EDECU will bypass the 10 minute limiter
NP drops below 96%
Greater than 3% between reference NP in actual NP
Greater than five per second NP droop exists and NP less than or equal to reference speed
Discuss their heading hold functions in FPS above and below 50 knots
The yaw axis of the FPS provides heading hold at air-speeds less than 50 knots and heading hold or turn coor-dination at airspeeds greater than 50 knots. For heading hold operation at airspeeds less than 50 knots, the heli-copter is maneuvered to the desired heading with feet on pedals.
Alternatively, below 50 KIAS the four-way collective trim beeper may be used to slew the aircraft to the desired heading.
In the event of an electrical failure, the ENG A/I start/bleed valves are going to revert to the mode. What advisory activates? How much Q will be lost from MAX TQ available?
Anti icing
ENG 1 ANTI-ICE ON or ENG 2 ANTI-ICE ON advisory
20% lost
discuss the safety devices limitations in emergency procedures of the rotor brake
EP: Rotor Brake ON
Actions:
If secondary indications are present:
If no secondary indications are present:
7 parts
a. Operating an engine against the gust lock is pro-hibited.
b. Rotor brake shall not be applied with engine(s) operating and rotor turning except during an emergency stop. Maximum rotor speed for emergency rotor brake applications is 76% NR.
c. Routine stops will be with engine(s) off, NR be-low 40% and with 150-180 psi applied to stop the rotor in not less than 12 seconds.
d. Minimum rotor brake pressure for engine start is 450 psi. Maximum rotor brake pressure for engine start is 690 psi.
e. Use of the rotor brake with engine(s) operating is restricted to single and dual engine starts and operations at IDLE only.
f. Single and dual engine starts and operation at IDLE with rotor brake on are not time limited.

Actions:
Rotor brake handle – check in detent and gauge pressure at zero
Check for secondary indications of brake pad dragging( smoke smell noise)
If secondary indications present: land as soon as possible
If no secondary indications present: land as soon as practicable
EP A1R
Where are the cold start capsule lights located?
What indications do they provide?
Located on the upper console
Provide status indicators and caution lights for the emergency cargo release battery Apu and Apu oil temperature and accumulator
EMER RLSE TEST LT - doing circuit testing a green status light will appear to indicate that the system is functioning properly
BATT LOW - yellow caution light indicating battery voltage is low on one of the batteries
BATT GOOD - Green status light indicating battery is charged (illuminated when a bat switch is placed in the test position)
OIL HOT - yellow caution lay indicating APU oil is hot
APU FAIL - yellow caution light indicating Apu failure
ACC LOW - yellow caution light indicating the accumulator hydraulic pressure is low
APU ON - Green status light indicating the APU is activated

How long must a caution be displayed before the pilot is able to acknowledge the caution?
2 seconds

What are the three annunciators on the top of the FMS and what do they indicate?
STS - Indicates change in system status. Go to the system status screen and acknowledge recognition of the fault to clear the annunciator.
FMS - Indicates a BIT failure within the FMS. Go to the system status screen to clear the annunciator.
MSG - Active, reserved for future use. Illuminates during test not currently used for any other function.
