TD-184 ✔ Flashcards
1
Q
- What indications cause the illumination of the CHECK EICAS caution?
A
Indicates engine oil temperature, engine oil pressure, main transmission oil temperature, and main transmission oil pressure are not within their normal range.
2
Q
- What is a FMS message alert? How would you check the FMS status alert “Check IVHMS”?
A
- The FMS displays status messages related to helicopter health and/or FMS navigation performance. The FMS displays the mes- sage alert MSG in yellow on the pilots’ MFDs, prompting the pilot to look at the FMS when a message requiring pilot attention is activated. Once activated by the FMS, MSG flashes for the first five seconds it is displayed, then remains displayed until the pilot has read and cleared the message on the FMS. The MSG is disabled when the as- sociated input from the FMS is invalid.
- Caused by “IVHMS Exceedance Alert State”

Q
- During startup, you experience a ENG 1 OIL BYPASS. What does this indicate and is this a normal indication?
A
- During cold weather starting, or starting with a partially clogged filter, the high-pressure drop across the filter will cause the bypass valve to open and the cautions to appear. The impending bypass indicator has a thermal lockout below 38°C to prevent the button from popping. A cold-start relief valve downstream of the filter protects the system by opening and dumping the extra oil to the gear box case.
- It is normal for the ENG OIL BYPASS caution to appear when starting an engine with oil temperatures below normal because of high oil viscosity and the ac- cumulation of oil filter contaminants. When the engine oil temperature reaches about 38°C (100°F) during warm-up, the caution should disappear.

Q
- During shutdown, the droops fail to return to the static position during rotor coast down. What are your actions? Additionally, how low will the blade/blades droop in feet from the ground?
A
- If one or more droop stops do not go in during rotor shutdown, shut down an engine to lower rotor idling NR in an attempt to seat the droop stops. If droop stops still do not go in, accelerate rotor to above 75% NR. Repeat rotor shutdown procedures slightly displacing cyclic in an attempt to dislodge jammed droop stop. If droop stops still do not go in, make certain that rotor disc area is clear of personnel and proceed with normal shutdown procedures while keeping cyclic in neutral position.
- When the droop stops do not return to the static position, the main rotor blades may droop to within 4 feet of the ground during shutdown.
5
Q
- When does the fuel indication on the Power Pod turn yellow? When does the FUEL 1 or FUEL 2 LOW caution Illuminate?
A
- 200 pounds in either tank
- FUEL 1 LOW or FUEL 2 LOW caution appear when the fuel level decreases to approximately 172 pounds in each tank.
6
Q
- You are planning a VFR flight to a class D airport. Predominant weather at your ETA is 1SM visibility and 500 ft. ceilings. Assuming no local restrictions, can you legally file VFR to this airfield?
A
Yes, you can file SVFR to controlled airspace.
7
Q
- List the additional improvements on the UH-60M that have been incorporated for transient droop response. Where are these items located?
A
The transient compensation system (in the DEC) provides significant droop improvement during some maneuvers by
- Monitoring engine torque (TQ transmitter)
- Collective rate of change and (MMU)
- NR rate of change. (left accessory module)
8
Q
- As an instrument rated pilot flying an instrument certified aircraft, when are you NOT required to file an IFR flight plan?
A
All Army aircraft that are instrumented for IFR flight and are flown by an instrument-rated pilot will operate on IFR flight plans except when
- Flight is primarily for VFR training.
- Time will not permit mission completion under IFR.
- Mission can only be accomplished under VFR.
- Excessive air traffic control (ATC) departure, en route, or terminal area delays are encountered.
- Hazardous weather conditions must be avoided.
- Aircraft is being flown single pilot.
