TD-178 ✔ Martin Flashcards
Define the following terms:
- Land as soon as possible,
- Land as soon as practicable,
- AUTOROTATE,
- EMER ENG SHUTDOWN,
- LOCKOUT,
- EMER APU START.
- The term LAND AS SOON AS POSSIBLE is defined as landing at the nearest suitable landing area (e.g., open field) without delay. (The primary consideration is to ensure the survival of occupants.)
- The term LAND AS SOON AS PRACTICABLE is defined as landing at a suitable landing area. (The primary consideration is the urgency of the emergency.)
- The term AUTOROTATE is defined as adjusting the flight controls as necessary to establish an autorotational descent and landing.
- The term EMER ENG SHUTDOWN is defined as engine shutdown without delay.
- The term LOCKOUT is defined as manual control of engine RPM while bypassing DEC/EDECU functions.
- The term EMER APU START is defined as APU start to accomplish an emergency procedure.
Where are the two locations that the Storm Scope information can be displayed?
- ND FULL
- PFD ARC
What is the NOTE associated with the Storm Scope as written in AWR 1726R15? What is the CAUTION associated with Storm scope WX-500 operation, and how long is storm activity stored in the memory and displayed?
NOTE:
The WX-500 Stormscope is susceptible to transmissions on the aircraft radios, and will intermittently present a false single lightning strike at the 7 o’clock position at approximately 40 nautical miles. This false strike will time out or the pilot may select “clear” on the MFD to remove.
CAUTION
Clusters of two or more discharge points in the strike display mode indicate thunderstorm activity when they reappear after clearing the screen. In the cell display mode, even a single discharge point may represent thunderstorm activity and should be avoided.
The stormscope memory can store up to 3600 individual strike or cell positions. The data is held in the memory for three minutes. After three minutes such expired data is deleted from the memory and the display.
How does the Mechanical Mixing Unit compensate for torque effect and translating tendency of the main rotor?
Collective to Yaw mixing Compensates for the Torque Effect of the main rotor.
As collective is increased, tail rotor pitch is increased and as collective is decreased, tail rotor pitch is decreased.
Collective to Roll mixing Compensates for Translating Tendency.
As the collective is increased the main rotor disk is tilted slightly left and as the collective is decreased the main rotor disk is tilted slightly back toward the right.
What conditions are conducive to retreating blade stall?
Conditions likely to cause Blade Stalls at High Airspeed:
- Low Rotor RPM (rotor droop)
- Turbulant Air
- Loads - High blade loading (High GWT)
- Altitude - High DA (High PA & Temp).
- High G-Maneuvers (high AOB or pulling Gs)
How do you create a storepoint and how many storepoints can be created?
Overfly Mark or Map Mark
24 B-Z (excluding O) - A is home Point (25)
Why does the yellow EIC miscompare annunciation appear and what is the miscompare threshold for TGT?
When a miscompare condition is detected, and has passed a certain threshold, the text label for the affected parameter turns to black text on a yellow background (Dobbel headed Yellow Arrow), and the yellow EIC miscompare annunciation appears above the PFD power pod
For TGT miscompare threshold is 7.3°C
In reference to TC 3-04.33, what is the WARNING associated with Rolling Takeoff?
Why should the aircraft’s heading be aligned with the take-off direction below maximum rate-of-climb airspeed?
WARNING
If the takeoff is aborted, it may be impossible to stop the aircraft before clearing the barriers (depending on aircraft weight, speed, surface composition, and size of the takeoff area). Some situations requiring this maneuver will usually result in very marginal single-engine characteristics. This increased risk factor will be addressed during the mission risk assessment process.
A/C HDG should be aligned to be able to abort and land the aircraft in a safe manner from present position.
