What is the statistical coverage when the calculated flight time is exactly 2 hours and a fuel ERA aerodrome is available?

The text specifies coverage for flight times 'less than 2 hours' and 'more than 2 hours'. For exactly 2 hours, the text does not provide a specific value; it only states 99 % coverage for more than 2 hours with a fuel ERA aerodrome available.

Q: What statistical coverage percentage is required for the contingency fuel when the calculated flight time is less than 2 hours?

99 % coverage plus 3 % of the trip fuel.

Q: For a flight with a calculated flight time of more than 2 hours and no fuel ERA aerodrome available, what is the required statistical contingency fuel coverage?

99 % coverage plus 3 % of the trip fuel.

Q: When is 99 % coverage (without the additional 3 %) acceptable for statistical contingency fuel?

When the calculated flight time is more than 2 hours and a fuel ERA aerodrome is available.

Q: What conditions must be met to use 90 % statistical coverage for contingency fuel?

The calculated flight time is more than 2 hours, a fuel ERA aerodrome is available, and at the destination aerodrome two separate runways are available and usable, one of which is suitable for type B instrument approach operations, and the meteorological conditions are in accordance with point CAT.OP.MPA.182(e).

Q: In the statistical contingency fuel method, what does the 90 % coverage case require regarding the destination aerodrome's runways?

Two separate runways must be available and usable, one of which is suitable for type B instrument approach operations.

ED Decision 2022/005/R

BASIC FUEL SCHEME WITH VARIATIONS — STATISTICAL CONTINGENCY FUEL METHOD

As an example of statistical contingency fuel, the following statistical values of the deviation from the planned to the actual trip fuel provide appropriate statistical coverage:

(a) 99 % coverage plus 3 % of the trip fuel if the calculated flight time:

(1) is less than 2 hours; or

(2) is more than 2 hours and no fuel ERA aerodrome is available;

(b) 99 % coverage if the calculated flight time is more than 2 hours and a fuel ERA aerodrome is available; and

(1) the calculated flight time is more than 2 hours;

(2) a fuel ERA aerodrome is available; and

(3) at the destination aerodrome, two separate runways are available and usable, one of which is suitable for type B instrument approach operations, and the meteorological conditions are in accordance with point CAT.OP.MPA.182(e).
