Is the implication that in this weight config (just cargo and empty seats) it is efficient to fly at 40,000ft?

- Robotbeat 7y agoYeah. For a given speed, a lower weight (with the same outer shape) means you need to fly at a higher altitude (where the air is less dense) to reach an optimal lift to drag ratio.
- t0mas88 7y agoYes, entering Oceanic you basically tell them: "Request track Delta, Flight level 350, Able 370, second choice track Charly" Translation: I want this route, the best altitude for me is 35,000 ft and at my current weight the maximum I can climb to is 37,000 ft. That optimum altitude is calculated by the flight management system.
