Question 1

1. On the PFD how does the pilot determine whether the wind values are current or remembered, and what is the wind direction? At what calculated wind speed is the wind speed and direction not displayed?

Answer 1

• Remembered wind is displayed with an R to the right of the wind speed.The wind symbology is white when the current wind information is displayed and yellow when the remembered wind is displayed.
• Wind direction is shown as an arrow relative to the current helicopter heading.
• Wind speed and direction is not shown when calculated wind speed is less than 4 knots.

Question 2

2. During startup and run-up, the Active Vibration Control System is found to be inoperative. Can the aircrew take-off and begin flying?

Answer 2

No, AWR 1726r19 contains the required equipment list for the UH-60M that supplements the required equipment list in AR 95-1, table 5-2. AWR 1726r19, Table 5-2 (required equipment list) states that the Active Vibration Control System (AVCS) is required for Day, Night, NVG, and IMC.

(AWR 1726r19 Table 5-2)

Question 3

3. What is the NOTE in TC 3-04.33 Chapter 6 regarding the digitization of the cockpit?

Answer 3

Question 4

4. With engine bleed air on, the available torque per engine is reduced as follows: The engine anti-ice on ______ . Cockpit/gunner heater on: Reduce torque available by _____ Anti-ice and cockpit/gunner heater on: Reduce maximum torque available by _____

Answer 4

4. With engine bleed air on, the available torque per engine is reduced as follows: The engine anti-ice on 20%Q . Cockpit/gunner heater on: Reduce torque available by 5% Q Anti-ice and cockpit/gunner heater on: Reduce maximum torque available by 25% Q

Question 5

5. The engine anti-ice will increase dual engine fuel flow ______ . Cockpit and gunner heat will increase fuel flow ______. With anti-ice and cockpit/gunner heat on fuel flow will increase ______.

Answer 5

The engine anti-ice will increase dual engine fuel flow +100 lbs/hr . Cockpit and gunner heat will increase fuel flow about 20 lbs/hr . With anti-ice and cockpit/gunner heat on fuel flow will increase About 120 lbs/hr .

Question 6

6. Increased rotor efficiency IGE is caused by what two factors?

Answer 6

• Less Induced Flow. Velocity of induced flow IGE is reduced. AoA up, induced drag down -> more vertical lift vector.
• Reduced Vortex Generation. In ground effect, downward and outward flow of air tends to restrict vortex generation. Outboard portion of each blade becoming more efficient.

Question 7

7. Identify the following

Answer 7

Question 8

8. Describe the two-challenge rule using FM 3-04.240.

Answer 8

The two-challenge rule allows one crew member to automatically assume the duties of another crew member who fails to respond to two consecutive challenges or when aircraft control is in question. (FM 3-04.240, p. E-7, para E-27)
