On what runway condition is a takeoff not permitted ?
Can a takeoff be started with a RWYCC of 0 ?
No, no takeoff or landing allowed
What is the minimum runway width to be cleared/treated ?
30m, a runway wider than 45m can be cleared to a width of less than 45m from the centerline. It should not be considered as narrow runway.
When is one eng taxi out prohibited ?
Updated OMB March 7: What are the technical requirement to be allowed to do a single engine taxi ?
Hydraulic: Yellow electrical pump serviceable
All hyd systems must be working
Electrical : gen 1 and APU Gen are serviceable

Updated with OMA OCT 22 - What are the first officer limit ?
Max crosswind including gust : 20kts
minimum RVR 550m
Approach minimum : CAT I ils, Minima of NPA, 5000m vis for circling
No contaminated rwy or slippery
no reported windshear
What is the minimum battery voltage when powering the A/C ? Can a APU fire test be done when below it ?
Minimum 25.5V
No, risk of APU extinguisher discharge
WARNING:
DO NOT PERFORM APU FIRE TEST IF BATTERY VOLTAGE IS AT OR BELOW 25.5 V AS THIS MAY RESULT IN THE DISCHARGE OF THE APU FIRE EXTINGUISHER BOTTLE. OMB 2.3.4.2
What is the maximum time you should hold the APU fire test PB ?
No more than 3 sec, otherwise it might auto shutdown and discharge APU fire bottle
WARNING:
THE AUTOMATIC SHUTDOWN OF THE APU AND THE DISCHARGE OF THE APU FIRE EXTINGUISHER BOTTLE MAY OCCUR IF THE FLIGHT CREW PRESSES THE APU FIRE TEST PB FOR MORE THAN 3 SECONDS. OMB 2.3.4.3
When should a complete IRS alignment be done ?
OMB 2.3.4.5
When should you do a fast alignment ?
A fast IRS alignment must be performed if a complete IRS alignment is not necessary and the difference between the IRS position and the FMGC position is at or above 5 NM
What is the minimum oil quantity ?
Note 1:(NEO) If the engines have been shut down for more than 60 min, decrease the above quantities by 3 qt to take into account the oil thermal expansion.
OMB 2.3.4.8
When should you set the pack flow to LO ?
A319/A320 : Less than 130pax
A321 : Less than 160pax
OMB 2.3.6.2
When is the navaid deselection not necessary ?
If GPS is primary even if NAVAID not working in the notam
What is the auto flaps retraction ?
Can be needed if green dot is higher than the speed constraint.
The flaps will auto retract at 210kts and leave only the slats to enable a speed of 220kts to be flown
What is the maximum altimeter difference on the ground ?
+-20ft between PFD
+- 100ft between ISIS and PFD
Altimeters and airport elevation +-75ft
Following the refuelling what is an abnormal discrepancy ?
Up to 6tons = 400kg
Between 6 and 12t = 500kg
more than 12 = 600kg
what should be done if, during the engine start, the ground crew reports a fuel leak from the engine drain mast ?
Run engine at idle for 5 min, if the leak disappears after 5min you can dispatch otherwise maintenance need to be called
OM B 2.3.8.1
When do you need to have the engine anti ice on for take off ?
When OAT is at or below 10°C and visible moisture (clouds, fog with vis less than 1600m, rain snow, sleet and ice crystals) and/or ground surface has snow, standing water or slush.
What is the ice shedding procedure for CEO ?
When in icing conditions and OAT +3° or less for more than 30min or significant vibration then:
What is the ice shedding procedure for NEO ?
When in icing conditions and OAT +3° or less for more than 30min or significant vibration then:
If the takeoff is not initiated within 120min in ground icing condition, the maintenance will need to perform an engine inspection.
Can you use wing anti-ice on the ground ?
No, the wing anti-ice will open for 30s on the ground then closed as long as the aircraft is on the ground.
When do you need the IGN for takeoff ?
When the runway has
What correction do you need to apply to the Flex temp in case of drop in QNH ? Use of ENG Anti ice ?
QNH reduction of 1 or 2 hPa = -1°c
ENG anti ice = -5°c
Following a change in QNH or the use of ENG anti ice for takeoff, what do you need to check for the new Flex temp ?
If the OAT or TREF is reached by applying the reduction in Flex temp then a new takeoff perf need to be computed.
TREF A319 = ISA +30°C
A320 = ISA +29°C
A321 = ISA +15°C
