Calculate the minimum flag fuel requirements (per the regulations) given the aircraft specifications and flight profile listed above. Assume you do not have an alternate airport, and there are no wind considerations. The Minimum flag fuel requirements for a would-be found under part 121.645. Since we do not have any wind. We can find our minimum fuel by adding fuel required for taxing and our trip, divided by the range. With this specific trip, our minimum fuel would be 15,600.624. 30 minutes before your flight is scheduled to depart, the ground operations representative for your company informs you that 10,000 pounds of cargo is being loaded on your aircraft. You have been assured (and you know) that A) there is room onboard your aircraft for the cargo, and B) the extra weight will be within center of gravity limits and takeoff limits for your aircraft. What is your new flag fuel requirements, given the new weight of the aircraft flying? Again, assume you do not have an alternate airport, and there are no wind considerations. To calculate this, we need to find the aircraft's new weight. The empty weight is 62,000 lbs, the fuel weight is the maximum usable fuel (32,000 lbs), and the cargo weight is 10,000 lbs. The aircraft's maximum takeoff weight is 110,000. The new flag fuel requirement would be 286,015. To compound things, you get a call from dispatch that says that a newly updated weather report indicates that a thunderstorm will move through the AUS area 45 minutes before you land, reducing the ceiling to a foretasted 1,000 feet, and visibility to 2 statute miles. While the thunderstorm is only supposed to last approximately 30 minutes, returning conditions to a sunny, partly cloudy VFR day at the time of landing (That’s Texas weather for you), what do you now need to ask the dispatcher about? What are your new flag fuel calculations, both with the cargo and without? When planning an alternate we have to have to have enough fuel to get us to the alternate plus 45 minutes after. We would need an extra 260 pounds of fuel without the cargo and an extra 70.6 pounds with the extra cargo weight.
During your preflight flight release review, the Captain informs you that they are a “High-Mins” Captain. What does that mean for your flight? A "High-Mins" Captain refers to a pilot who is authorized or qualified to operate under higher minimums (minimum weather conditions) than standard for a specific approach or airport. This designation is often associated with captains who have received additional training and certification to conduct approaches and landings in weather conditions that would otherwise require diversion or alternate actions. For this flight, it means we might be able to get into our original planned airport, but we should still plan for an alternate just in case.
