Question 1

MEA definition

Answer 1

Minimum En-route AltitudeBetween 2 fixes, terrain clearance of 1000’ (or 2000’ over high ground) within airway (5nm either side of centre).

Minimum Sector AltitudeClearance of 1000’ above obstacles in a ring of usually 25 miles around a fix.

Question 5

Take off alternate not required criteria

Answer 5

Weather not less than applicable landing minima.

Question 6

Take-off alternate requirements for 2 engined A/C:

Answer 6

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.

Question 7

Destination and Alternates weather restriction on take-off

Answer 7

At ETA for destination and/or alternate met report must be above applicable minima.

Question 8

Two Alternate Aerodromes must be planned when:

Answer 8

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!)

Question 9

Destination Alternate not required to be planned:

Answer 9

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.

Question 10

Destination planning weather criteria:

Answer 10

ETA ±1hr RVR/vis as on the approach chart;

(Non-precision: ceiling >50’ above MDH for CDFA)

Question 11

Ceiling definition:

Answer 11

More than 50% of the sky covered with cloud i.e. not few or scattered, but broken or overcast.

Question 12

Alternate planning criteria:

Answer 12

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.

Question 13

Question 22

RVR for landing. Min values CAT 1 ILS

Answer 22

• Touchdown RVR is controlling (550m or as published).

Answer 24

The higher of:

1. 5% of trip fuel with NO en-route alternate;
2. 3% of trip fuel WITH an en-route alternate.

Question 25

Alternate Fuel must consist of enough fuel for:

Answer 25

1. A missed approach from MDA/DA;
2. Missed approach to cruise level and route to alternate;
3. Approach and landing at alternate.

Question 26

Final Reserve Fuel definition:

Answer 26

Fuel to hold for 30 mins at 1500’ above aerodrome level in ISA at ELM at the Alternate.

Question 27

Additional Fuel

Answer 27

a) If the planned fuel doesn’t cover engine failure or depressurisation. It is enough for:

1. Descent and flight to adequate aerodrome;
2. Hold for 15 mins at 1500’ in ISA:
3. Approach and landing.

b) Enough for 15 mins holding at 1500’ in ISA if no alternate planned.
