What are the Three Phases of Operations for a mission?

• A. Alert, Takeoff, Descent/Landing/Taxiing
• B. Planning, Enroute, Debrief
• C. Preflight, Launch, Recovery
• D. Prepare, Infiltrate, Exfiltrate

Answer: (A)

Three operational phases of a mission are readiness, execution, and return. The sequence Alert, Takeoff, Descent/Landing/Taxiing captures that progression: first, the crew and equipment are alerted and prepared for action; second, the aircraft departs and carries out the mission; third, the aircraft descends, lands, and taxis back to base, completing the operation and securing the scene.

Alert reflects the transition from standby to active mission, including crew notification, equipment checks, and any scramble or readiness actions. Takeoff represents the actual execution phase where the mission is carried out. Descent/Landing/Taxiing covers the return to base, post-mission recovery, and secure shutdown, which is essential to close out the operation properly.

Other options describe different lenses on mission work—planning stages or generic flight phases—but they don’t depict the end-to-end three-phase progression used here, where readiness, execution, and recovery are the defining sequence.
