OMA 8.1 Flight Preparation Flashcards
Commander won’t commence flight without (9 lines)
Airworthy aircraft
MEL / CDL covered
Documents
Ground Facilities at Dest
Fuel, Oil, Oxygen
MSA and minima OK
Alternate available
Load Balanced and Secured
TOW OK for obstacle clearance
Terminal arrival gives how much terrain clearance (inc MSA)
1000’ to Intermediate Approach / Platform
Route MORA gives how much terrain clearance?
1000’ clearance below 5000’
2000’ clearance above 5000’
Minimum value 2000’ AMSL
20nm from centreline
How is MGA / Minimum Grid determined
Elevation rounded up to next 100’
Add 1000’ up to 6000’
Add 2000’ above that
Can be omitted over water
When is Lido temperature correction used? What is corrected?
When -10ºC or below
Minima
Minimum altitudes after FAF
FAF (unless limit given)
ATC must be informed when doing so
What is Bernoulli Effect on altimeters?
Strong winds at airports in valleys, pressure will drop (overread, underfly). Up to 450 ft at 65kt.
Lowest turn on departure?
400’ AAL
unless SID / EOSID stipulates
Company MFAs
(Climbout, Radar, Visual, outside MSA, OEI, Off-route)
Climbout: as SID (EFB climb perf to MSA if none)
Positive Radar: iaw MRC
Visual: must see all terrain
Outside MSA: OPF indicated MORA
OEI: Net gradient (EOSID will achieve)
(Gross Stabilising / Level Off generally clears all terrain in AOC area)
Off-route: MGA
Temp corrections see two charts 8.1.1.3 (High / Low altitude)
Should ATC give temperature corrections to MRC? Should they give safe off-route altitudes?
Yes. Minimum vectoring should give safe clearance until resuming own navigation
When should you climb immediately to MSA (3)
If unsure of position, no timely reply from ATC, radar failure when off-procedure.
Aerodrome suitability considerations (10)

RFFS (6, A321- 7)
Weather
RFFS Categories
Low traffic aerodromes?
Temporary downgrades?
All alternates? in UK?
Code 6, Code 7 for A321
Low traffic, Code 5 (shown on OFP)
Temporary downgrades: Code 2 or less (under 72 hours)
All alternate: Code 5, Code 4 in UK
Above is for planning, but can be considered in case of downgrade in flight.
Non-ETOPs limit for adequate aerodromes?
60 mins at OEI cruise
400 NM
380 NM for A319
Standard temp, still air
Weather Permissible Aerodrome definition
At anticipated arrival:
Reports / forecasts at or above minima
Surface condition reports permit safe landing
Take-off alternate criteria?
One hour still air at OEI cruise, ISA
At actual TOW
When are two destination alternates needed? (3)
Destination below planning minima
No METAR
Landing performance not assured (due to dependence on favourable weather / specific runway)
Planning Minima
Cat III / II/ OTS / LTS
Cat I
APV
NPA
Circling
Cat III / II/ OTS / LTS: Cat I RVR
Cat I: NPA RVR/Vis (cloud above MDH)
APV: NPA minima
NPA: NPA RVR/ Vis
(Vis + 1000m, MDH + 200’)
Circling: Circling
Either one of the destination or the alternate must have a non-RNAV approach.
Difference between Cat A/B/C aerodrome?
A: Routine
B: Specific Briefing
B rest’d: Restrictions (no training)
C: Training or visit
Signing tech log confirms compliance.
Unusual approaches, weather, circling above 1000’, perf limitations all considered.
Areas / regions can also be complex and require training
Take Off Minima?
