A helicopter making a round trip from a helodeck with refueling capabilities to an unmanned platform will take 45 minutes each way. The helicopter should be carrying enough fuel to last __________.

Correct Answer: Option D — 2 hours

Standard aviation safety requirements for offshore helicopter operations require sufficient fuel for the total flight time plus a mandatory 30-minute reserve. A 90-minute round trip plus a 30-minute reserve totals exactly two hours of required fuel endurance.
