Cost index simbrief
If you normally use a specific cost index, you'll want to enter that into SimBrief when you create your flight plan, or it'll pick one for you. As for cruise altitude, that would really depend on which direction you're going and weight of the aircraft. Also take weather into consideration. In a stiff headwind, the climb speed will increase up to maybe about 310 KIAS (as a ballpark) and Mach .80; with a strong tailwind the speed will go down to maybe 270 and Mach .76 (again, ballpark - exact Cost Index being used affects these adjustments). The cost index is a number used in the Flight Management System (FMS) to optimize the aircraft's speed. It gives the ratio between the unit cost of time and the unit cost of fuel. With this number, and knowledge about the aircraft's performance, it is possible to calculate the optimal speed for the aircraft, which results in the lowest total cost. In this tutorial I’ll show you all the information provided on a flight log from a LIDO operational flight plan and how to accurately complete time and fuel checks en-route The sector is based This is exported via the print function to the routes folder of fslabs and to p3d for activesky and a pdf. I load my sim up with the aircraft at a stand and livery for the airline. I go into the mcdu enter in my callsign and hit init request. Then the uplink loads my ZFW, ZFWcg, fuel, alternate, route and cost index. Regarding these PFPX profiles, keep in mind they give "best efficiency" fuel figures in term of operations. I mean it's really really difficult to beat them except if you get lucky with unexpected tail wind. It's kinda little fun challenge to perform the flight within schedule and fuel budget.
CIs vary so much. The most "realistic" way is to use a random number generator and let it pick a number for you in the range of, say, 10-90. If you have a real schedule you can try plugging it into simbrief.

The fundamental rationale of the cost index concept is to achieve minimum trip cost by means of a trade-off between operating costs per hour and incremental fuel burn. 1.

1 Nov 2019 I have no idea how simbrief is calculating it though. Still, the flight times Sim Brief comes up with are fairly realistic compared to the real routes For example lets say in sim brief I set my Extra Fuel, my cargo and my IF you look at PMDG aircraft setting, you can set a cost index which will 28 Feb 2018 using a Cost Index which starts there and then the FMC applies an adjustment for headwind or tailwind.
