Which statement is correct regarding time waivers in separations?

• A. Time can be waived by the flight crew
• B. Time can be waived by air traffic control
• C. Time cannot be waived
• D. Time can be waived only in radar conditions

Answer: (A)

Time waivers focus on when the required time gap between aircraft can be reduced or set aside if safe spacing can be maintained through other means and proper coordination. The best answer reflects that the flight crew has the authority to waive the time constraint, as long as they can maintain adequate spacing using their judgment and the approved procedures, with ATC coordinating to ensure there are no conflicts. This reflects the responsibility and flexibility of the piloto-in-command in managing spacing when conditions allow. The other options either imply control by ATC alone, claim no waiver is possible, or tie waivers only to radar situations, which don’t align with how such waivers are described in this context.
