What are the minimum fuel requirements for IFR operations using turbojet aircraft?

• A. Fly to first airport, complete one full instrument approach, fly to the alternate, then 45 minutes at normal cruising speed
• B. Fly to first airport, then immediately to alternate
• C. Fly directly to alternate and then 60 minutes
• D. Fly to first airport and immediately land

Answer: (A)

For IFR planning of turbojet operations, you must carry enough fuel to fly to the destination, be able to complete at least one full instrument approach there, then proceed to the alternate, and still have a 45-minute reserve at normal cruising speed. The inclusion of a full instrument approach means you have the capability to land if weather allows and, if necessary, execute a missed approach and continue with the plan to the alternate. This combination ensures you have a safe margin for delays, holding, or unexpected changes.

The other options don’t meet this requirement: skipping the destination approach, or bypassing the instrument-approach capability, or omitting the required reserve, would leave you with insufficient fuel planning for a turbine-powered IFR flight.
