OM-B SOP Flashcards
What are the items in aircraft acceptance?
Recal 3 seconds, hyd, eng, oxy page. Techlog & MEL (check certificates and time of daily check).
OFP
Flysmart + date, QRH, OEB, available systems (aircraft configuration summary)
Lido green tick
Aircraft acceptance: perform (sign techlog)
What to do when receiving a start up clearance?
Switch on beacon. This is the trigger for PM to switch on transponder. Request checklist.
What is the maximum altimeter difference on ground?
Between PFDs, 20 ft and 100ft with standby compass. Maximum 75ft from airport elevation.
What is the starting sequence of the engine? CEO/NEO
N2 rises, start valve line green, bleed pressure indicator green, oil pressure increase
16 % CEO / above 20% NEO indication of active ignitor A/B
22% (C) / above 20% (N) N22, FF increases and EGT and N1 increase
50% (C) N2, start valve closing and ignitor indication off
55% (N) N2 ignitor indication off, 63% N2 start vale closing
What are the engine idle parameters? C/N
Engine idle parameters
CEO NEO
N1 19.5% 19%
N2 58.5% 68%
EGT 390°C 520°C
FF 275 kg/hr 290 kg/hr

What is the minimum temperature for oil on the NEO for takeoff?
19 degrees
What are icing conditions?
OAT/TAT below 10 degrees and visibile moisture present
When do we apply the ice shedding procedure?
30 minutes or more taxi time with a temperature of below 3 degrees or when engine vibrations occur.
In freezing conditions every 10 mins for CEO.
What is the ice shedding procedure?
For CEO: 70 percent N1 for 30 sec every 30 mins.
For NEO: 50 percent N1 for 5 sec every 60 mins.
When is an engine inspection needed on the NEO?
If in temperatures below 3 degrees for over 120 mins.
What are the flex temperature corrections?
1 degree for every 2 hPa drop in QNH. 5 degrees for engine anti ice on
What are the Tref temperatures?
A319 30 degrees + ISA
A320 29 degrees + ISA
A321 15 degrees + ISA
When/how to charge the battery?
When below 25.5V. Battery pb to auto, external power on. After 20 mins, turn battery’s off and check if above 25.5V.
How to check the batteries
Turn off, check elec page, in 10 sec ampere must be below 60 and decreasing. If not: charge battery.
What are the things you see & hear on an engine fire warning test?
7 items:
CRC
Eng fire pb light on
Squibs lit
Disch lit
Master warning
ECAM
Warning light at engine master switch
What are the stable approach criteria for vertical path?
Within 1 dot glideslope, 3/4 dot vertical deviation (100ft), not 4 white/red on papi.
