TD16 Flashcards
Each DCU accepts___ , ______and___inputs and sends them to the mfds. The DCUS also generate a___caution which indicates certain engine or transmission parameters have exceeded the normal operating ranges.

The first FMS to complete the bit becomes the _______, while the other becomes the backup bus controller or ___.
Bus controller
Remote terminal

Overspeed protection protects the power turbine from destructive overspeeds. The system is set to trigger at___% NP1 or NP2 and will result in a fuel shut off causing the engine to___. When NP1 or NP2 is reduced below the overspeed limit fuel flow is returned to the engine and engine ignition will come on to provide___.
120%
Flame out
A relight

What are the warnings and caution associated when operating an engine in DEC/EDECU LOCKOUT?
WARNING 1: NR can also decrease as a result of exceeding the maximum torque available due to reaching TGT limiting maximum fuel flow or NG limiting without an associated hardware failure (rotor droop).
WARNING 2: Going to lock out to obtain additional power does not remove maximum fuel flow or NG limits. NR will decrease below normal operating range if maximum fuel flow or NG limits are exceeded.
CAUTION: When engine is controlled with engine power control lever in lockout engine response is much faster and TGT limiting system is inoperative. Maintain NR within normal operating range.

When the HUMS-E switch is pressed, what information is recorded and for how long?
Intermittent events, including vibration, cockpit noise for 30 seconds, rotor track and balance for 5 seconds and flight parameter data for 30 seconds
15 seconds before and 15 seconds after the switch is pressed

Define effective translational lift
Occurs with the helicopter at approximately 16 to 24 knots when rotor completely outruns the recirculation of old vortexes and begins to work in relatively undisturbed air. Flow of air through the rotor disc is more horizontal. Induced flow and induced drag are reduced. The angle of attack increases which makes rotor operate more efficiently

During a hover for low wind conditions, aircraft should be headed into wind. _____ crosswind or tailwind may increase torque required by up to___over zero wind values.
3 to 5 kts
4%
Under what conditions is it considered normal to hover with the transmission oil temperature in the yellow precautionary range?
Prolonged hovering flight in temperatures above 35° c at higher gross weight
