Who may authorize taxing of aircraft without a taxi signalman, providing the ramp has clearly defined taxi lines and parking spots?

• A. Flight Deck Officer
• B. Ramp Supervisor
• C. Commanding Officers
• D. Aircraft Commander

Answer: (C)

Authority to deviate from standard ground-handling procedures rests with the person in command of the unit. If the ramp is clearly marked with taxi lines and parking spots and the overall risk is reduced, the commanding officer may authorize taxiing without a taxi signalman. The CO holds ultimate responsibility for safety and mission readiness and can grant such an exception when justified. The other roles operate within established procedures and do not have the authority to waive the requirement on their own.
