Final answer:
IFR minimum fuel requirements state that you need fuel to your initial destination, alternate airport, and additional fuel for at least 45 minutes of flying time.
Step-by-step explanation:
IFR minimum fuel requirements state that you need fuel to your initial destination, alternate airport, and additional fuel for at least 45 minutes of flying time. This additional fuel is known as the 'reserve fuel.'
The reserve fuel is necessary to accommodate any unforeseen circumstances, such as weather changes, air traffic congestion, or unexpected delays during the flight, ensuring the safety and completion of the flight.
For example, if your flight from New York to Los Angeles is expected to take 5 hours, you would need enough fuel for the journey, plus fuel for an alternate airport, and an additional 45 minutes of reserve fuel.
