What information must be provided to request flight in controlled airspace?

To request flight in controlled airspace, providing the date, time, and duration of the operation is essential. This information is crucial because it helps air traffic control (ATC) understand the specifics of your flight, which is necessary for managing the airspace effectively. By knowing when the operation will take place, ATC can ensure that there are no conflicts with other aircraft and can provide the necessary clearances in a timely manner. It allows for proper planning and coordination to maintain safety and efficiency in controlled airspace.

The other options do not directly pertain to the specific requirements for flight authorization within controlled airspace. While weather conditions, fuel type, and maintenance history are important for overall flight safety and operation, they do not constitute the primary information needed to request access to controlled airspace.
