When inputting a destination and alternate into the Longitude 700 flight plan, which action ensures the plan aligns with available weather and approach options?

• A. Enter destination and at least one alternate, verify weather/approach availability, ensure fuel and ETAs align with plan.
• B. Enter destination only and do not check weather.
• C. Enter the alternate and assume favorable weather.
• D. Submit plan without fuel or ETA checks.

Answer: (A)

This question tests ensuring flight plan viability by validating weather and available approaches and by confirming fuel and timing fit the plan before submission. When you input both a destination and an alternate, you establish a legally required contingency and a target for evaluating feasibility. Verifying weather and approach availability at the destination and the alternate ensures there is a viable landing path under current conditions and with the aircraft’s capabilities. At the same time, confirming that fuel on board, reserves, and estimated arrival times line up with the plan keeps the flight within safety margins and regulatory requirements, so you won’t run out of fuel or find yourself unable to meet ETAs if a reroute or hold becomes necessary. Skipping weather checks, assuming favorable conditions, or submitting without fuel or ETA verification leaves you exposed to unsafe or non-compliant situations.
