TD 47 Flashcards
- In reference to FM 3-04.203, what is the caution associated with wire hazards? What are two specific cues for locating wires?
Wires are nearly impossible to see with NVDs. They are also difficult to see during certain times of the day; for example, when an aviator is flying into a setting sun. Wires and poles can become coated in dust and snow making them even more difficult to identify. During any mission briefing, an aviator must review the presence of wires and identify the location and status of the wire-hazards map.

Where are the two locations that the Storm Scope information can be displayed?
Navigation Source Data Display and ARC Display on PFD
What is the NOTE associated with the Storm Scope as written in current AWR1726? What is the CAUTION associated with Storm scope WX-500 operation, and how long is storm activity stored in the memory and displayed?
The WX-500 Stormscope is susceptible to transmission on the aircraft radios, and will intermittently present 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. (pdf pg 8)
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. (TM -10, pdf pg, 401)
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. (TM -10, pdf pg, 400)
How does the Mechanical Mixing Unit compensate for torque effect and the vertical thrust component of the canted tail rotor?
Yaw to Pitch: The MMU provides aft input to the main rotor system as tail rotor pitch is increased and forward input as tail rotor pitch is decreased.
In reference to FM 3-04.203, what are three specific hazards to terrain flight safety? Give one example for each.
Physical: Man-made and Natural
Weather: Restricted visibility, Wind condition
Human Factors: Fatigue, obstacle detection ability
How do you create a storepoint and how many storepoints can be created?
Storepoints are created in flight and used for navigation or targets of opportunity. Storepoints may be created by overflying a location and pressing MARK on the FLYOVER STORE screen by selecting a position on the map or by pressing the FIX key. Pressing the FIX key a second time will transition you to the STOREPOINT DATA screen. The data conveyed here will be the location where the FIX key was first pressed and will be designated the next available letter designation.
As many as 24 storepoints may be created, and will be designated as B through Z less O. Storepoint A is designated as the hover waypoint and is displayed on the PFD, ARC, HOVER and NAV displays. (TM -10, pdf pg. 368)
Why does the yellow EIC miscompare annunciation appear and what is the miscompare threshold for TGT?
The EICAS parameter values from the two DCUs are compared to detect possible faulty data. The comparison is always between DCU 1 and DCU 2 data, regardless of the selected EICAS data source for display. Due to processing of parameters separately by the DCUs, it is normal to see slight differences between the pilot and copilot EICAS readouts. Each DCU supplies both engine 1 and engine 2 data, but there is no comparison of engine 1 data to engine 2 data. When a miscompare condition is detected, the text label for the affected parameter turns to black text on a yellow background, and the yellow EIC miscompare annunciation appears above the PFD power pod.

In reference to UH-60 Series dATM, 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?
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.
