What is the typical sequence for fuel management during the cruise phase in the Longitude 700?

• A. Plan diversions based on weather and fuel availability.
• B. Monitor fuel burn, compare actual burn to plan, consider route adjustments for efficiency and reserves.
• C. Refuel mid-cruise at every waypoint.
• D. Ignore burn data and rely on a gauge only.

Answer: (B)

The key idea is actively managing fuel during cruise by comparing what’s actually being burned with what was planned, then using that information to stay within margins and keep reserves intact. You monitor fuel burn continuously, check actual burn against the forecast, and, if there’s a gap, you adjust the route, altitude, or speed to improve efficiency and ensure you have enough fuel for contingencies and reserves. This disciplined cycle helps accommodate winds, weather, and routing changes while preserving required reserves.

Mid-cruise refueling isn’t a standard practice, relying only on a gauge ignores the need to verify actual burn versus plan, and simply planning diversions without this ongoing monitoring misses the real-time adjustment step that keeps you within safe margins.
