In the pre-flight fuel scheme for aeroplanes, which two failure scenarios are compared to determine the additional fuel requirement?

The engine failure and the loss of pressurisation scenarios are compared, and the one requiring a greater amount of fuel is used.

AMC4 CAT.OP.MPA.181 Fuel/energy scheme -- Fuel/energy planning and in-flight re-planning policy -- aeroplanes

Q: How should the additional fuel for an aircraft failure that significantly increases fuel consumption be calculated for a flight?

The additional fuel should be calculated according to the engine failure or loss of pressurisation, whichever requires a greater amount of fuel, at the most critical point along the route.

Q: What is the basis for determining the amount of additional fuel required in the event of an aircraft failure that significantly increases fuel consumption?

The calculation should be based on the engine failure or loss of pressurisation, whichever requires a greater amount of fuel, at the most critical point along the route.

Q: At which point along the route should the additional fuel for a significant fuel consumption increase due to an aircraft failure be calculated?

At the most critical point along the route.

Q: What does AMC4 CAT.OP.MPA.181 specify about the calculation of additional fuel for an aircraft failure that significantly increases fuel consumption?

It specifies that the additional fuel should be calculated according to the engine failure or loss of pressurisation, whichever requires a greater amount of fuel, at the most critical point along the route.

BASIC FUEL SCHEME — PRE-FLIGHT CALCULATION OF USABLE FUEL

The additional fuel required by the type of operation in the event of an aircraft failure that significantly increases fuel consumption at the most critical point along the route should be calculated according to the engine failure or loss of pressurisation, whichever requires a greater amount of fuel.
