OMA Section 8

Question 1

What are the minimum flight altitudes (MFAs) that shall be adhered to by easyJet aircraft for departure, enroute, arrival & off route?

Answer 1

Aircraft above published MSA when departing and arriving. Above OFP published MORA enroute. Above applicable MGA if flying off route.

Question 2

How much obstacle separation is provided by published MSA, MORA & MGA?

Answer 2

MSA - 1000ft within 25nm of fix
MORA - Obstacles > 5000ft = 1000ft Sep
Obstacles < 5000ft = 2000ft Sep
10nm either side of track
MGA - Obstacles > 6000ft = 1000ft Sep
Obstacles < 6000ft = 2000ft Sep

Question 3

Where can you find temperature, pressure & wind corrections for MFAs?

Answer 3

OMA 8.1.1.3

Question 4

Can you convert Met Visibility into RVR & what limitations are there on doing so?

Answer 4

Yes you can. Table in OMA 8.1.3.4.
It should not be used when:
-reported RVR is available
-conversion results in an RVR <800m
-calculating take off minima

Question 5

Difference between Cat A, B, C aerodromes?

Answer 5

A - Non-complex, treated as routine
B- Required self briefing e.g CCI, AVB
C - Special crew qualification required, aerodrome visit or specific training

OMA 8.1.2.5

Question 6

For weather planning minima what forecast period needs to be considered for destination & alternate aerodromes?

Answer 6

1 hour before & 1 hour after ETA

OMA 8.1.2.2.2.1

Question 7

What is relevant for destination planning minima for NPA & Precision approaches?

Answer 7

For NPA, ceiling & RVR/Met vis
For precision, RVR only

If minima expressed as RVR, met visibility should be above
RVR/Met vis conversion should not be used for planning

Question 8

What are the approach planning minima for destination alternate & ERA?

Answer 8

Cat II/III - Cat 1 RVR
Cat 1 - NPA cloud base & visibility
NPA - NPA minima +1000m +200ft
Circling - Greater than circling minima

OMA 8.1.2.2.2.4

Question 9

When do we need 2 destination alternates? (3 things)

Answer 9

-Weather at destination below minima
-Weather at destination unavailable
-Landing perf requirements at destination alternate cannot be assured due to dependence on specific wind component or runway state

OMA 8.1.2.2.2.3

Question 10

What are the distance/time limits on travelling to destination & ERA alternates?

Answer 10

Max 60 min single engine flight time

Answer 11

Located within 60 mins single engine flight time.
Distance limit is 320nm

Question 12

Is dispatch without a destination alternate allowed?

Answer 12

Yes, but only if below criteria are met:

-dispatched under the “No destination alternate aerodrome procedure” which means additional fuel to fly for 15 mins at 1500ft above aerodrome elevation
-duration of the flight must not exceed 6 hours
-Two separate runways are available and usable & weather 1 hour before and after ETA must be cloud base 2000ft and Vis 5km

OMA 8.1.2.2.2.4

Question 13

What is the absolute take-off minima?

Answer 13

RVR 125m

Question 14

What are the planning minima for a nominated take-off alternate & when is one required?

Answer 14

Required when the weather conditions preclude a return to departure aerodrome taking into account single engine or any MEL restriction, whichever is more limiting.
Weather reports or forecasts for the take-off alternate should be above the applicable minima for the expected instrument approach.

OMA 8.1.2.2.2.2.

Question 15

Regarding take-off alternates, what are the implications of taking off above max landing weight?

Answer 15

Auto-land is not certified above max landing weight so a Cat I take-off alternate is required if LVPs are in force at departure aerodrome

Question 16

For take-off, if the RVR or visibility is not reported can you still take off?

Answer 16

Yes, captain can make judgement call.

Question 17

Ceiling and Vis required for a visual approach?

Answer 17

2500ft and 5km

OMA 8.1.3.6

Question 18

Explain cloud ceiling

Answer 18

Ceiling is more than half the sky, so BKN or OVC only

Question 19

Why would you depart without a nominated destination alternate?

Answer 19

-For take-off performance reasons
-Isolated aerodrome

Question 20

Difference between fuel & commercial alternate?

Answer 20

Fuel alternate requires less fuel but has minimal facilities available in case of divert
Commercial alternate has fuel and is equipped to deal with passenger needs e.g shops, catering etc

Question 21

What is the minimum rescue & firefighting service category for A319, A320 & A321?

Answer 21

A319/A320 - 6
A321 - 7

Departure/destination aerodromes can be reduced to 5 at aerodromes with little movement and further to 4 if reduction not exceeding 72 hours & is notified by NOTAM.

Alternate aerodromes - UK 5, Non UK 4

Question 38

Regarding low fuel states what does ‘minimum fuel’ mean to ATC? What about mayday?

Answer 38

Minimum fuel - all other airfields options have been used up & any change to current clearance will result in landing below final reserve Mayday - will land below final reserve Approach fuel 17kg/min
