System Malfunctions Flashcards
What is the preferred landing type for a HYD failure?
Flat attitude rolling LDG
- Minimises control inputs
Due to HYD system issues, the HYD accumulator has lost pressure, how might this impact the aircraft and what can the crew do?
Loss of effective:
- Rotor brake
- Wheel brakes
- Parking brake
Crew should land zero/zero or if running LDG, slow down with cyclic and COL
MPS 1 has had a malfunction, what aircraft functionality is impacted by MPS 1 only? (2)
- HYD boost to the yaw servos, additional control forces required
- Loss of ESAS
MPS 1OR MPS 2 have malfunctioned, what aircraft functionality is impacted by either? (3)
- Yaw control authority decreased by 10%
- AP1/2 + AFCS autotrims reaching limits faster
- Sensor info on HYD Page
You have a HYD caution appear, what are the FP actions?
“HYD malfunction”
A - Safe H/H/AS, “This is a land ASAP EMRG”
N - Landing site?
C - Mayday for immediate landing
A - B4 LDG Cx, SDIP, PWP
Land ASAP
You are the flying pilot when an AFCS class A alarm presents, what are your actions?
“AFCS Class A”
A - “Hands and feet on controls” —> Establish safe H/H/AS, climb 1000ft AGL as req
N - Turn towards closest airfield
C - PAN as req
A - Consult checklist —> B4 LDG Cx, SDI, PWP
Land via —> Normal angle, early flare, hover term
You are the flying pilot when BATT.T presents, what are your actions?
“Battery 1/2 temperature”
A - Safe H/H/AS —> “BAT 1/2 OFF, this is a land ASAP EMRG”
N - Landing site?
C - MAYDAY
A - BAT.T Cx, B4 LDG Cx, SDIP, PWP
Land via flared ATT RLDG —> If BAT.T remains, EMERG shutdown/egress
You are flying pilot, when RTU 1/2 class B presents, what are your actions?
“RTU 1/2”
A - Safe H/H/AS, Nil BF
N - Turn to airfield
C - Comms after Cxlist
A - Consult Cx, RTB normally
What do the CCP “FAIL” and “ALT” lights mean?
Fail: The CCP has failed in some way and is working buddy mode, which mirrors the other CCP
ALT: The other crew member is in ALT mode
What happens if your CCP has the “FAIL” light and you select ALT on the HMSCP?
Your CCP will revert to fixed mode, meaning you can’t change the channels from what you have already set
What are the crews actions when ECAS is presented? What does ECAS stand for?
“ECAS”
A - Safe H/H/AS
N - Turn towards the airfield
C - Cx first
A - Consult Cx
Normal APP/LDG
ECAS = Electronic crew alerting system
What and where is the CDU BAS button?
BAS is on the top left of the CDU, next to MEP. Pressing is button effectively switched which MFD is considered the main display
You have lost ALT 1 and ALT 2, what happens?
- MFDs 1 and 2 go blank
- AFCS fails completely
- Radios fail
What are some examples of non essential aircraft equipment? (4)
- RMS/sighting
- External/internal lights
- Air COND
- Pitot/Windscreen heating
Which XMSN cautions have boldface, and what is it? (2)
- Rotor Brake (Class A) —> Confirm RB unlocked/guarded
- MBG Pressure Low (Class A) —> Establish level flight
