Final answer:
An airplane flying under IFR must carry enough fuel to fly to the first airport of intended landing and then for an additional 45 minutes.
Step-by-step explanation:
A. True
An airplane flying under Instrument Flight Rules (IFR) must carry enough fuel to fly to the first airport of intended landing and then for an additional 45 minutes. This requirement is in place to account for unforeseen circumstances, such as weather conditions or air traffic congestion, that may delay the landing or require an alternate airport. By having this extra fuel, the airplane can safely continue flying and have enough reserve to reach a suitable landing location.
