B4yM4x- Posted February 28, 2018 Share Posted February 28, 2018 Hi there, I am planning a mission that will involve harrier taking off from carrier, landing in FARP, get refueled, armed and then proceed with a strike mission. Question is, for the first part of the mission, knowing the required weight for a VL on the FARP, my drag index, lowest altitude I can fly (based on flight path from carrier to FARP), how can I use the performance charts to identify how much fuel I should load? I know there are takeoff, climb and range charts, but they are based on the weight of the aircraft, which in my case is actually the variable -> I need to know the fuel I have to carry.. Any suggestions? Thanks Link to comment Share on other sites More sharing options...
Erk104 Posted February 28, 2018 Share Posted February 28, 2018 (edited) Taking off from a farp may be better done on the return trip after ordinance has been spent. You can experiment using the mission editor to find out how much ordinance you can carry and fuel quantity. You can select the amount to stay under 20,000 pounds and then go in game to find out how much that percentage is in cockpit.

Frederf Posted February 28, 2018 Share Posted February 28, 2018 All fuel planning is done with what amount you want to end with and working backward piecemeal. Land with X lbs. Approach allowance X lbs. Descent from altitude X lbs. Cruise rate times distance X lbs. (distance is total distance minus climb and descent) Takeoff and climb amount x lbs. Start and taxi allowance x lbs. Example mission: Cruise 10kft, GW 25klb, DI 40, distance 100nm, 300 KCAS climb and cruise Performance reference A1-AV8BB-NFM-400 Reserve 600 lbs. Landing (VL) allowance 200 lbs. Max range descent 600 lbs. (14nm) Cruise 889 lb. (68nm, 75lb/min) Climb 240 lbs. (8nm) Takeoff data assuming maximum fuel flow for 1m, 249 lbs. Start and taxi assuming 10m at 900 lb/h, 150 lbs. Total 2,928 lbs. 1 Link to comment Share on other sites More sharing options...
