Startup WCN

Question 1

8.18 Before Starting Engines- “WWC”

Answer 1

• W-Before eng operation, ensure m/r tie downs are removed
• W-While restrained, I must be able to manipulate all flight controls, propulsion, fuel and fire switches and T handles.
• C-Do not grasp foam pad to adjust seats or damague may occur.

Question 2

8.19 Cockpit equipment checks - APU control switch on- “NN”

Answer 2

• “APU CLEAR”
  N if APU accum low does not appear, pull manual override lever on accumulator manifold until APU reaches self- sustaining speed.
  N-If APU fails, do not turn off BATT switch. Note BITE indications.

Question 3

3 Generators APU Switch on- “XWW”

Answer 3

STAB/TACAN CLEAR

• STAB will slew full down due to AC power being applied.
• ensure nobody is 3’ of tacan when power is applied to A/C

Question 4

3.2 EDECU - check signal val code- “NNN”

Answer 4

N-Check 25% on Q indicator for 701D to verify DAS plug installed.
N-EDECU configuration may be verified on FMS status page.
N-Code displayed after AC power application at a rate of 4sec on/2off during startup and 30secs after both eng’s shut down w/AC power applied.

Question 5

8 MASTER WARNING PANEL- Check #1 Eng out, 2Eng out, low rotor rpm segment lights are illuminated- “N”

Answer 5

N-If segment light does not appear, pull 1/4” in then push back in to reset bulb

Question 6

12 Press FCC failure reset switches

Answer 6

N- EGI’s must be in ORIENT phase before faults will reset

Question 7

16 flight controls- check 1st flight of the day - “WNWNC”

Answer 7

W-Perform control sweeps (cyclic) to see if aviator worn gear is in the way (Restrictions).
N-Check 1.5” free play in collective
W-During collective movement, if either PRI SERVO FAIL cation appears, bypass valve is jammed, DNF.
N-Limit force applied to pedals only to contact a system stop with SAS?BOOST off to prevent flight control bearing/bolt noises.
C-If hydraulic access door is open, ensure rotor blades are not over nose to prevent contact with WSPS.

Question 8

19 Stabilator- check “W”

Answer 8

If any part fails, do not fly the A/C.

Question 9

21 FMS initialization-check as required “NNN”

Answer 9

N- FMS defaults to last known position and automatically updates date, time, and position with GPS data once available.
N-INIT will automatically engage once GPS acquires satellites and determines location.
The calculator PERFORMANCE function is only for value reference after verifying correct configuration of the A/C.

Question 10

23 Set up MFD/FD/FMS for mission “N”

Answer 10

N- Only 2 UTO’s can be loaded using the mission card. Load additional UTO directly into the IDM. OPERATIONAL must be displayed prior to the JVMF initialize/login (appx 2min).

Question 11

8.20 STARTING ENGINES “C”

Answer 11

C-Prior to eng start, ensure rotor blades are aligned with A/C centerline +-20degrees or damage may occur if blades are static over the UES

Question 12

3 Gust Lock Engaged caution - verify off “N”

Answer 12

N-if gust lock caution is not visible on CAS page, verify on EICAS page

Question 13

3.1 Stab Unlocked caution - Verify off “WN”

Answer 13

N-If stab is unlocked with rotors turning, stab could contact the rotor
N-if STAB UNLOCKED caution is not visible on CAS page, verify on EICAS page.

Question 14

Engine(s) Start “NWCNNCCNCN”

Answer 14

N-If conditions permit; engines may be started with inop or not installed rotor brake
W-If rotor brake moves to slippage, shutdown engines or release brake
C If started with IGN off, abort start and do not turn on
N-There will be no NP or Q, MAIN XMSN PRESS caution will remain, and all no.1 and no.2 hydraulic cautions remain on until the rotor brake is released
N-FUEL PRESS caution should disappear before engines stabilize at ground idle. If FUEL PRESS lights momentarily illuminate, do not use FUEL BOOST PUMP CONTROL switches to extinguish
C-PCL’s from idle to off. do not depress the starter button, it can damage the auto start switch actuator.
C-Cyclic neutral, collective less than 1’ above full down. Pedals centered until 50%RPM R to avoid anti flap bracket+bushing damage
N- If starter drops + PCL is off, press and hold starter button until 52-65% Ng is reached
C-Starts w/ rotor brake off and rotor engagements: minimize cyclic inputs to prevent droop-stop pounding.
N-NG may be above 65% w/ starter dropout due to 1sec delay

Question 15

Eng abort start criteria

Answer 15

“TP NET”
TGT-lightoff w/in 45sec
P w/in 45sec
NP1/NP2 w/in 45sec
ENG starter on caution disappears before reaching 52%Ng Speed
TGT reaches 851before idle is attained (63%Ng).

Question 16

11. System Checks

Answer 16

• Ng Speed 63% or greater within 3% of each
• NP 1 or 2 not in 20-40 or 60-90range
• XMSN Press at least 20
• Eng oil press at least 22
• 1+2 HYD PUMP caution disappeared

Question 17

13. Hydraulic leak test system “NN”

Answer 17

N- Move switch to test and release, if not, it will leave the circuit open and will not test.
N- If backup pump is still running, reset off to auto for next test.

Question 18

14. Tail Rotor Servo Check

Answer 18

N -If backup pump and #2 T/R do not illuminate, the LDI is inop

Question 19

2.(engine runup) Eng PCL’s FLY “WN”

Answer 19

W- Restrict the rate of movement when the tail wheel doesn’t denote LOCK. Rapid application could result in turning the helicopter and causing injury or loss of life.
N- For rotor brake operation, you must have approx 45%NR for S-E and 57% NR D-E prior to advancing EPCL’s.

Question 20

5. Gen 1 Fail and Gen 2 Fail cautions disappear above 97%NR “N”

Answer 20

N- During SE ground operation with the collective full down, NP/NR may read 99%. Raise collective slightly to bring NP/NR to 100%

Question 21

(parking and shutdown)
17. Collective raise no more than 1”
“NN”

Answer 21

N- If external power is required it shall be connected and EXT POWER switch to RESET.
N- If a blind shutdown must be performed complete normal shutdown of #2 engine first.
