OMA Flashcards
When is a daily inspection valid and for how long?
After the last flight and after 6pm.
Period of validity: 48 hours from the midnight of the inspection.
When do we do an aircraft search?
(6)
It’s always a search unless the aircraft is in EU and it’s last sector came from the EU/UK.
Search:
Departing from UK inc JER IOM GIB
Departing from anywhere and previous sector came from non EU exc. Switzerland (Inc. Tel Aviv, Egypt)
Cold aircraft
Aircraft parked outside tarmac area for pax boarding.
Left outside maintenance hangar.
Any time crew believe security may have been compromised.
Aircraft search/bag reconciliation requirements after pax offload at diversion airport
If diversion airport in UK:
- if prev dep location from uk: 3 rows procedure
- other prev dep location: full search (everyone disembarks, unless no one gets off)
Diversion location anywhere else:
- if prev dep location from UK or EU: 3 row procedure
- if prev dep location anywhere else: full reconciliation process I.e. reconcile all remaining pax with baggage, offload any unclaimed baggage and full search
What requirements needed to depart with no usable alternate?
Either:
15 mins additional fuel at 1500ft
& flight < 6 hrs
& 2 separate runways (with 2 separate appr procedures based on different navaids, and 2 separate landing surfaces, so if one blocked, other one usable)
& Wx +- 1 hr ETA - ceiling: 2000ft or circling + 500ft, vis: 5k+
Or:
Destination a/d isolated (which Easyjet does not have approval for)
RFFS required for a/c types & acceptable downgrades?
A319/320: 6
A321: 7
Downgrades:
Dep/dest - 5 (for low volume ADs and indicated on OFP) or 2 categories below when notified by ATC/NOTAM/ATIS < 72 hrs
Alternates (t/o, dest and enroute) - non UK 4, UK 5
Ultimately commanders decision (considering other factors other than RFFS)
Application of Aerodrome forecasts
+/- 1 hr ETA
RVR/vis for precision (CMV/RVR diversion not used at planning)
Ceiling as well for non precision & circling
BECMG: deterioration applic at START of change
Improvement applic at END of change
Gusts disregarded and mean wind should be in limits
TEMPO: Deterioration-
disregard if transient/showery
apply if persistent (Eg mist) but disregard gusts
Improvement - disregard
PROB TEMPO
Deterioration- MAY be disregarded
Improvement- SHOULD be disregarded incl all winds
When do you need takeoff alternate? What are requirements for takeoff alternate?
Met conditions greater than cat 3a (one eng inop) & weight< max landing weight (A319 has been demonstrated to auto land up to 69t if req in emergency, but not ideal)
or any MEL if minima more restrictive
Takeoff alt within 1 hour still air flight time, OEI cruising speed, ISA conds
How many types of commanders discretion and authority are there? What are they?
6 (5 discretion, 1 authority)
Extend FDP
Reduce FDP
Increase rest
Reduce rest
Extend cumulative duty limits
Commanders AUTHORITY to exceed FRM Roster Rules
When is a landing assured?
Can be completed in event of any forecasted deterioration of wx AND any plausible single failure of ground/airborne facilities e.g. CAT II/III to Cat I
What are low fuel states?
“MINIMUM FUEL”- non-emergency, only fuel for single intended aerodrome and any change in clearance results in < final reserve
“MAYDAY, MAYDAY, MAYDAY, FUEL” - nearest aerodrome where a safe landing can be made would result in less than final reserve
What does MFA stand for?
What are the 3 different types and their clearances?
Minimum flight altitude
MSA - 1000ft obstacle clearance within 25nm
Route Mora - 1000ft clearance up to 5000ft obstacle, above this 2000ft clearance. Within 20nm of the route centreline.
Minimum grid altitude - 1000ft clearance up to 6000ft obstacle, above this 2000ft clearance. Used off track.
How many feet per hpa?
30ft
When do we need two alternates?
Wx below minima at destination
Landing performance not assured (due wind/rwy state)
No wx available
Landing close to a night ban.
If your destination has the following minima what minima does your alternate need?
CAT II OR III
CAT I
NPA
CIRCLING
CAT II OR III needs CAT 1
CAT I needs NPA
NPA needs NPA +1000m rvr 200ftMDH
CIRCLING needs circling
Aerodrome categories?
Cat A - Non complex
Cat B - Requires specific briefing (eg. Audio visual)
Cat B restricted - Specified restrictions (eg No 3*, x-wind limits)
Cat C - Special training, visit or sim.
When the commander signs the flight plan what is he signing for?
Oma 8.1.2
For a standard route. That you have familiarised/briefed yourself on the aerdrome being operated into.
For a complex route, as above plus have taken a visit/sim training.
(8.1.2.7)
Oma 8.1.7
That you have adequate oil and fuel in line with easyjets fuel policy.
What determines that our aircraft are Cat C?
Their Vat (IAS at Threshold) 121-140kts.
Minimum rvr for take off?
What lighting is required to get this?
125m
High intensity edge and centreline lights, multipul rvr.
When can we do a met vis to rvr conversion?
In flight only with no available rvr info.
At the planning stage met vis is used directly against rvr, as rvr is not shown on a TAF.
When should a met vis to rvr conversion not be used?(4)
When rvr is avail
At the planning stage
For calculating take off minima
When the conversion comes out less than 800m
Coming in on approach what would you do if rwy/centreline/TDZ/approach lights are inop?
QRH Sup info, low vis table for landing.
Leads to a search NALS, BALS, IALS in lido gen for applicable rvr.
NALS most limiting, standard cat 1 dh(i.e 200ft) gives a required rvr 1200m.
(1400m good up to 300ft dh)
What is final reserve fuel?
30 mins at 1500ft over your destination alternate aerodrome.
What is additional fuel?
When can we take it?
Fuel for 15 mins at 1500ft over destination aerodrome.
Taken if we take no alternate.
APU
ENG ANTI ICE
WING ANTI ICE
Fuel burn?
2kg/min
1kg/min
1kg/min
Taxi fuel; fuel burn?
10kg/min
Trip fuel. How much can we increase/decrease this figure by based on changing the track miles?
Increase track miles, add 5kg per mile
Decrease track miles, subtract 4kg per mile.
Can we reduce contingency fuel?
Yes.
If SFC data is available to the greater of:
CONT90 or 5mins at 1500ft (205kg min).
If no SFC data, down to the greater of:
3% of trip fuel or 5mins 1500ft.
Still need an enroute alternate.

16
What age range is a child classed as?
2 to 11
