COAS QUESTIONS Flashcards
WHAT IS THE LAND ASAP DEFINITION?
If RED LAND ASAP then land ASAP at the nearest airport which a SAFE landing can be made.
If AMBER LAND ASAP then consider landing at the nearest suitable aerodrome
FCTM AOP-30-10
WHAT ARE THE FUEL URGENCIE CALLS?
MINIMUM FUEL call means that all planned aerodrome options have been reduced to a specific aerodrome and committed to it. Could mean landing with less than FINAL RESERVE.
MAYDAY FUEL. When a landing means with less than planned reserve.
OMA 8.3.7.1.5
WHAT DOES THE EVAC SWITCH PB?
Pressing the PB:
- horn sounds in the FD and CABIN
- EVAC light flashes in the CABIN and FD
FCOM DSC -23-40-10
WHAT ARE THE DIFFERENCES BETWEEN THE PRECAUTIONARY LANDING AND EMERGENCY LANDING?
PRECAUTIONARY-under normal circumstances there will be no ne requirement for the CC to evacuate.
PRE-PLANNED EMERGENCY LANDING- could mean FORCED landing or EMER on the ground. 3-10mins to secure the cabin and brief CC.
AOC CSPM
TALK ABOUT THE FIRE DETECTION SYSTEM AND IT’S LOOPS?
The ENGs and APU have:
-2 loops A + B
- Fire Detection Unit
Once A+B senses heat above a TEMP the fire warning is triggered.
the loops consist of 3/4 ENG fire sensing elements in the:
-Nacelle pylon, ENG core, ENG fan section
-1 in the APU compartment.
Once an sensing element detects heat a signal is sent to the FDU
FCOM DSC-26-20-10
WHAT ARE THE HOLDING POINTS AT RUNWAY?
Position A & B stated in the GEN PART 1.3.2.5.8
WHEN ARE 2 DESTINATION ALTERNATES AND NO ALTERNATES REQUIRED?
2 alternates must be selected when the appropriate Wx is below the planning minima.
No MET info is available
Landing performance cannot be assured at DEST.
Flight time <6hrs
2 separate r/ways with WX reports from 1hr before and after ETA
Ceiling of 2000ft or circling +500ft whichever is greater
VIS 5km+
Additional fuel is carried ( 15mins at 1500ft agl)
OMA 8.1.2.2.2.4 / OMA 8.1.2.1
WHEN ARE THE SPEED BREAKS ACTIVE?
-When the main landing gear is compressed and the V is >72kts
+
-spoilers armed, thrust levers at/near idle.
-spoilers not armed and reverse selected on at least 1 ENG
-they will retract when at least 1 thrust lever is at 20* on a touch & go.
WHAT IS THE DIFFERENCE BETWEEN A GRN HYD PUMP FAIL AND LOSS OF FLUID?
Loss of fluid will mean loss that system and the associated flight controls.
loss of pump is less of a problem as the PTU will pressurize the green system.
IF THE BLUE PUMP OVERHEATS WILL THIS EFFECT THE RAT?
NO it drives a separate pump but will only have 2500psi instead 3000psi.
WHEN DOES THE RAT DEPLOY?
The RAT deploys automatically if AC BUS 1+2 are both lost. It can also be deployed manually by the overhead panel.
FCOM DSC-29-10-20
CAN THE BLUE SYSYEM STILL BE POWERED BY THE RAT IF THE FLUID IS LOST?
No as both pumps use the same reservoir.
WHAT IS THE PLANNING MINIMA FOR A DESTINATION ALTERANTE & ERA?
Planning minima: LTS-CATIII = CAT I RVR CAT I = NPA/VIS (ceiling at/above MDH) APV = NPA Minima NPA = NPA RVR/VIS + 1000m (ceiling at/above MDH +200ft) Circling = Circling
OMA 8.1.2.2.2.4
WHAT IS THE REQUIRED FUEL ON A STANDARD ROUTE?
WHAT IS FINAL RESERVE MADE OFF?
TAXI, TRIP, CONTINGENCY, ALTERNATE, ADDITIONAL (IF REQ), FINAL RESERVE, EXTRA.
FINAL RES. is 30 minutes holding spd at 1500ft agl at ALT
ADDITIONAL. 15mins at 1500ft agl when operating without an alternate.
OMA 8.1.7.5
WHAT ARE THE CAT123 MINIMAS, RVRs & VISUAL LIGHTS?
CAT I - >200FT >550m = elements of app lights, threshold(marking,lights), VIS GS indicator, t/down zone markings or lights, r/way edge lights
CAT II - <200FT >100FT, >300M, VIS REQ 3 consecutive lights and a lateral element.
CAT IIIA - <100FT, >200M, FAIL PASSIVE 3 lights consecutive - app centreline, t/down, r/way c/line, r/way edge, a combination of those lights.
CAT IIIB - <100FT, <200M >75M FAIL OP with DH= 1 light only. w/out DH = no vis req.

WHEN IS A T/OFF ALTERNATE REQUIRED AND WHAT IS THE CRITERIA?
Required when performance or MET conditions preclude a return to the dep. aerodrome.
It shall be within 1hr flight time with OEI cruising speed. 320nm.
Wx reports shall be at or above applicable minima.
OMA 8.1.2.2.2.2
WHAT IS THE A/C STATUS IF YOU LOSE AC BUS 1?
AC ESS PB should be used to recover it then a/c will be CAT 2 with slow slats, check performance for fuel predictions
FCOM ABNORM PRO - ELEC.
WHAT IS THE RULE ON DRINKING BEFORE DUTY?
NO drinking within 10hrs of the duty and drinks kept to a minimum within 14hrs of duty. No more than 5units within 14hrs
