OMA 8-11 Flashcards
MEA definition
Minimum En-route AltitudeBetween 2 fixes, terrain clearance of 1000’ (or 2000’ over high ground) within airway (5nm either side of centre).
MORA definition
Minimum Off-Route AltitudeProvides clearance within 10nm either side of route centreline.
(MORA has an ‘a’ e.g. 5000a)
Clears terrain by 1000’ below 5000’ and 2000’ above 5001’
Aerodrome RFFS Category for CL604/5
Level 4
MSA definition
Minimum Sector AltitudeClearance of 1000’ above obstacles in a ring of usually 25 miles around a fix.
Take off alternate not required criteria
Weather not less than applicable landing minima.
Take-off alternate requirements for 2 engined A/C:
Within 1 hour flying time at OEI cruise in still air at actual TOM.
Met indicates wx above landing minima ± 1 hour either side ETA.
Runway and wx suitable for single engine landing.
Destination and Alternates weather restriction on take-off
At ETA for destination and/or alternate met report must be above applicable minima.
Two Alternate Aerodromes must be planned when:
Weather reports indicate that ETA ± 1Hr the weather will be below planning minima or;
No met is available.
Fuel to reach the farther must be planned (obviously!)
Destination Alternate not required to be planned:
If the planned flight duration is <6 hours and;
- 2 separate runways are available and;
- Met forecast ETA ±1 Hour the approach from MSA can be made in VMC.
Or
- The destination is remote (No Alternate exists).
With no alternate, extra fuel to hold for 15 mins at 1500’ must be carried and;
A non-RNP (inc RNAV GNSS) approach must be available.
Destination planning weather criteria:
ETA ±1hr RVR/vis as on the approach chart;
(Non-precision: ceiling >50’ above MDH for CDFA)
Ceiling definition:
More than 50% of the sky covered with cloud i.e. not few or scattered, but broken or overcast.
Alternate planning criteria:
For ± 1hr ETA:
CAT1: Ceiling and vis above non-precision approach minima;
Non-precision: Ceiling +200’ (+50’ for TAG CDFA) and vis +1000m above non-precision minima.
Circling: Ceiling and vis above circling minima. (For TAG, ceiling is +50’)
A non-RNP (inc RNAV GNSS) approach must be available.
RVR minimum for take-off
No LVP = 400m
with LVP = 125m
Lowest minima for circling approach:
CAT C: 600’
MDH; 2400m vis
Lowest minima for visual approach:
RVR 800m
Lowest MDH for GNSS (LNAV) approach:
250’
Lowest MDH for localiser only:
250’
Lowest MDH for VOR only approach:
300’
Lowest MDH for VOR/DME approach:
250’
Lowest MDH for NDB
350’
Precision approaches in CL604
ILS only
RVR for landing. Min values CAT 1 ILS
- Touchdown RVR is controlling (550m or as published).
- Mid-point must be above 125m
- Stop-end must be above 75m
Reserve Fuel consists of:
- Contingency fuel
- Alternate fuel
- Final Revserve
- Additional fuel
Contingency Fuel is:
The higher of:
- 5% of trip fuel with NO en-route alternate;
- 3% of trip fuel WITH an en-route alternate.
Alternate Fuel must consist of enough fuel for:
- A missed approach from MDA/DA;
- Missed approach to cruise level and route to alternate;
- Approach and landing at alternate.
Final Reserve Fuel definition:
Fuel to hold for 30 mins at 1500’ above aerodrome level in ISA at ELM at the Alternate.
Additional Fuel
a) If the planned fuel doesn’t cover engine failure or depressurisation. It is enough for:
- Descent and flight to adequate aerodrome;
- Hold for 15 mins at 1500’ in ISA:
- Approach and landing.
b) Enough for 15 mins holding at 1500’ in ISA if no alternate planned.
Passenger masses:
- Male 203 lb;
- Female 163 lb;
- Children 77 lb;
- Bags 33 lb.
CTOT Slots
Aircraft should be at the hold by the CTOT. The Slot is 5 mins before and 10 mins after the CTOT.
