OPS 1.375
In-flight fuel management
An operator shall establish a procedure to ensure that in-flight fuel checks and fuel management are carried out according
to the following criteria:
(a) in-flight fuel checks.
1. a commander must ensure that fuel checks are carried out in-flight at regular intervals. The usable remaining fuel
must be recorded and evaluated to:
(i) compare actual consumption with planned consumption;
(ii) check that the usable remaining fuel is sufficient to complete the flight, in accordance with paragraph (b) “Inflight
fuel management” below; and
(iii) determine the expected usable fuel remaining on arrival at the destination aerodrome;
2. the relevant fuel data must be recorded.
(b) in-flight fuel management.
1. the flight must be conducted so that the expected usable fuel remaining on arrival at the destination aerodrome is
not less than:
(i) the required alternate fuel plus final reserve fuel, or
(ii) the final reserve fuel if no alternate aerodrome is required;
2. however, if, as a result of an in-flight fuel check, the expected usable fuel remaining on arrival at the destination
aerodrome is less than:
(i) the required alternate fuel plus final reserve fuel, the commander must take into account the traffic and the
operational conditions prevailing at the destination aerodrome, at the destination alternate aerodrome and
at any other adequate aerodrome, in deciding whether to proceed to the destination aerodrome or to divert
so as to perform a safe landing with not less than final reserve fuel, or
(ii) the final reserve fuel if no alternate aerodrome is required, the commander must take appropriate action and
proceed to an adequate aerodrome so as to perform a safe landing with not less than final reserve fuel;
3. the commander shall declare an emergency when calculated usable fuel on landing, at the nearest adequate aerodrome
where a safe landing can be performed, is less than final reserve fuel.
4. additional conditions for specific procedures.
(i) On a flight using the RCF procedure, in order to proceed to the Destination 1 aerodrome, the commander
must ensure that the usable fuel remaining at the decision point is at least the total of:
trip fuel from the decision point to the Destination 1 aerodrome; and
contingency fuel equal to 5 % of trip fuel from the decision point to the Destination 1 aerodrome; and
destination 1 aerodrome alternate fuel, if a destination 1 alternate aerodrome is required; and
Final reserve fuel

(ii) On a flight using the PDP procedure in order to proceed to the destination aerodrome, the commander must
ensure that the usable fuel remaining at the PDP is at least the total of:
Trip fuel from the PDP to the destination aerodrome; and
contingency fuel from the PDP to the destination aerodrome calculated in accordance with Appendix 1 to
OPS 1.255 Paragraph 1.3; and
fuel required according to Appendix 1 to OPS 1.255 Paragraph 3.1.d
