If a limitation affects the planned route, which is an acceptable course of action after evaluation?

• A. Maintain the original plan and hope for favorable conditions
• B. Cancel the flight and return to base
• C. Proceed with the planned route without recalculation
• D. Recalculate performance within the published envelope and, if needed, divert with ops

Answer: (D)

The main idea is to redo the flight planning using the airplane’s published performance data whenever a limitation impacts the planned route. You must recalculate performance within the published envelope, taking into account current weight, balance, temperatures, winds, and the required altitudes and restrictions. This re-evaluation shows whether you can still safely meet climb, cruise, descent, and fuel requirements with the planned route. If the recheck indicates you’re within limits, you can proceed with a revised plan. If it shows you cannot meet the constraints, the safe course is to divert in coordination with operations to an approved alternate. Relying on favorable conditions or continuing without recalculation would ignore the aircraft’s limits and safety margins.
