Where to find aircraft performance data

Recommended Posts

I am using a utillity called Little Navmap where it is a flight planner for flight simulators. To calculate fuel, you need Aircraft Performance data. The Little Navmap website don't have all aircraft performance files and would rather have to make the Aircraft Performance manually. I can fly the plane for the data but sometimes it is inconvienient. I am trying to find Aircraft Performance data related to fuel like Fuel Flow, Reserve Fuel, Usable Fuel, etc. Some sources don't have all the performance data and the websites or sources i visit don't have the fuel related data. If there is a source where i can find most aircraft performance data especially with fuel related data, it would be helpful because i can fill the data onto Little Navmap.

To be honest I am not quite sure if you can find something precise to what you want since there are a number of factors that determine fuel required for a trip. If you are looking for raw data, there is TopCat which I do not use because it didn't have the aircraft that I fly which is the B747-8. Also, I am not really sure how up to date it is.

I do use simbrief (www.simbrief.com) which is free and does provide fuel needed for a planned trip based on a whole slew of parameters you provide, (Cost Index, Taxi to runway times, ZFW, flight duration, cruise altitude, reserves, etc etc). Simbrief does use that information to calculate the required fuel for the trip based on the parameters they have for that particular aircraft you are using. I really don't use their flight planner per se (I use another flight planner) but I do use the fuel numbers they provide to load my fuel; which I have found to be pretty accurate. Let's say I haven't run out of fuel in the 6 years I have been using it. At least the numbers they provide are a good base and you don't have to enter the aircraft performance manually.

Hope this helps you.

Cheers.

Forshaw.

What specific airplanes do you have in mind?  Perhaps there are some folks here that already have and would be willing to share that information.
