Simulator 2024 Aircraft Version Development Build info master Describe the bug The fuel planning button is always visible on the FUEL & Load page Expected behavior Should only be visible when: Before engine start and the flightplan contains a cruise flight level and zero fuel weight + zero fuel weight cg are inserted. Not displayed on the page otherwise. Steps to reproduce Open the Fuel & load page. References (optional) No response Additional info (optional) No response Discord Username (optional) No response
Simulator Version 2024 Aircraft Version Development Build info master Describe the bug The maximum allowed value for thrust reduction, acceleration and engine out acceleration altitudes are 45000 feet. Expected behavior Should be the maximum certified flight altitude (39800) Steps to reproduce Try inserting a thrust reduction, acceleration or engine out acceleration above 39800 feet. References (optional) No response Additional info (optional) No response Discord Username (optional) bruno_pt99
Simulator Version 2024 Aircraft Version Development Build info master Describe the bug It is possible to insert an altitude constraint up to 45000 feet.
