Final Answer:
The required minimum fuel reserve for a turbojet aircraft flying under IFR conditions with no alternate airport is based on regulations, typically involving a contingency fuel reserve of 5% of the total trip fuel.
Step-by-step explanation:
When operating a turbojet aircraft under IFR with no alternate airport, regulations mandate a specific fuel reserve to account for unforeseen circumstances. This reserve typically includes a contingency fuel, which is calculated as 5% of the total fuel required for the entire trip. This contingency fuel allows for deviations, unexpected delays, or changes in flight plans, ensuring that the aircraft has sufficient fuel to reach its destination safely.
Understanding and adhering to fuel reserve requirements is essential for pilots to maintain the highest standards of safety and compliance with aviation regulations. Proper calculation and allocation of fuel reserves contribute significantly to the overall success and security of the flight.
