Question 1

DEC/EDECU improves transient droop compensation how?

Answer 1

DEC/EDECU rec’s signals from NR and collective and are compared with NP and Q signals. A priority signal is sent to trim the torque motor in the HMU to compensate for the demand.

Question 2

How does the DEC limit TGT?

Answer 2

DEC commands HMU to limit fuel when TGT reaches it’s limiting value.

DE= TGT 879 +-9
Contingency= 903 +-9

Question 3

when EDECU limits TGT? (at 2.5 contingency)

Answer 3

• NP below 96%
• Greater than 3% droop between reference NP and actual NP.
• Greater than 5% per second NP droop rate exists and NP less or equal to NP reference speed

(note: edecu not dependent on Q below 50%)

DE= TGT 879 +-9
Contingency= 903 +-9

Question 4

what are DEC/EDECU fault codes?

how are they displayed?

Answer 4

• Failure on a selected input signal will display Q code.

- 4seconds on, 2 seconds off on MFD

Question 5

Controls and functions of ICS panel
ICS
VOX
HOT MIC
CALL
RMT
BU
ICU status light

Answer 5

-interface comm radios, nav radios, and intercom.
-ICS: default mode after initialize of ICS
-VOX: voice keying
-HOT MIC:constant keying of ICS interphone.
-CALL: overrides all other interphone comms at all stations exc. warnings and alerts.
-RMT: Enables RAD SEL on collective for radios and selections
BU:bypasses ICS in a degraded analog mode.
ICS status light: link of ICS and ICU broken

Question 6

procedures for adjusting VOX

Answer 6

• press VOX 2 seconds-VOX light flashes

- Adjust VOX by MVOL control

Question 7

if you go IIMC, do you have to inform CDR?

Answer 7

no unless violation of:

• FAA
• ICAO (inl’ civil aviation organization)
• Host nation

Question 8

when operator/crew member check list used?

shall, should may?

Answer 8

from preflight through leaving A/C.

• Shall: mandatory
• Should: preferred
• May: acceptable method.
