Question 1

The battery supplies power to what busses with the Batt switch off?

With the switch on?

Answer 1

Batt sw. OFF, the battery supplies power to the Battery Utility Buss (only)

Batt sw. ON, power distributed from Battery Utility Buss to Battery Buss then to DC Essential Buss

Question 2

What should be done if, during aircraft parking and shutdown, the APU generator fails after GENERATORS NO. 1 and NO. 2 switches - OFF?

Answer 2

If during shutdown APU generator fails after engine gen OFF (or EPCLs to IDLE), connect Ext. pwr., or shut-down engine number 2 first (with gen. 1 on-line), then shutdown number 1 (on batt pwr).

Question 3

Activation of the #1 GEN BRG or #2 GEN BRG caution requires a precautionary landing to be made. True or False? Explain.

Answer 3

False.
If ON for more than 1 Min, it requires a write-up in the form DD 2408-13-1.
Can fly 10 flighthours on (same) BRG Caution light, before maintenance repair.

Question 4

What is the Caution and Note associated with landing?

Answer 4

Landing CAUTION:
During roll-on landing aerodynamic braking with aft cyclic is permitted with the tail wheel contacting the ground. Once the main wheels touch down, the cyclic must be centered prior to reducing collective. Excessive aft cyclic may cause droop stop pounding and contact between main rotor blades and other portions of the helicopter.
Aerodynamic braking is prohibited once the main landing gear touches down. Use brakes to stop the helicopter.

Landing NOTE:
Because of the flat profile of the main transmission, pitching the helicopter nose up as in hover, may cause a transient drop in indicated main transmission oil pressure, depending on degree of nose-up attitude.

Question 5

Identify the following antennas:

Answer 5

Question 6

Given the following cruise conditions what is the Minimum and Maximum dual engine IAS and explain how is it calculated?

TEMP: 40 Degrees
PA: 2000’
ETF (ATF): 1.0/.92 (.96)
ACFT GWT: 20000 LBS

Answer 6

Using cruise chart (pg 7A-55) and cross referencing ATF with GW, and using 10 / 2.5 min limits:

Min/ Max - Dual Engine: 0 - 145 KIAS
20K LBS line does not intercept with 10 min line)

Min/ Max Sngl Engine: 47 - 100 KIAS
Using low ETF adjusted between 0.85 & 2.5 min line ->
Read IAS where line intercepts 20K LBS line.

Question 7

Is starting a fuel check or changing a radio frequency without announcing it an example of communicating effectively and timely, if not why?

Answer 7

To communicate effectivly crew should “announce and acknowledge decisions and actions”
