FlightGear is able to render the scene for the ballistic high altitude flight the X-15 is capable of (at least on a modern graphics card), but it needs some special adjustments to do so. Assume the visibility at arc top should be 500 km: | |||

The X-15 electrical and hydraulic systems are peculiar because they use a pair of hydrogen peroxide | The X-15 electrical and hydraulic systems are peculiar because they use a pair of hydrogen peroxide fuelled APUs to provide power to the aircraft instead of being connected to the main engine. While the mechanical power drain from those systems can be neglected for regular aircraft where most of the fuel is used for propulsion, this cannot be done for accurate computation of fuel consumption from the APU. And depletion of APU fuel can leave you without a controllable aircraft ... | ||
