Free Flight Planning Tool

I released a big update yesterday, the flightplan now has performance included for automatic calculation of:

  • Take-off and landing distances
  • Take-off and landing speeds
  • Take-off and Go-around thrust / power
  • Distance, time and fuel to climb
  • Cruise fuel flow and TAS
  • Distance, fuel and time to descent
  • Holding fuel consumption

10 performance models can be created and coupled to any aircraft created on the config page. If you have multiple Cessna 172 configurations on the config page (normal and utility for example) you only need to create one performance model and couple to both aircraft.

The initial set-up may take some time as you’ll need to create a weight and balance + performance model using POH data for the aircraft you want to use this for. After that full flight planning including performance and weight & balance takes minutes rather than hours.

When creating a performance model a few things are important to know and follow:

  • Weights, pressure altitudes etc. in columns needs to be in ascending order.
  • All cells need to be completed, even if data is not available, for example POH only showing landing performance for max take-off weight → copy the same table into both weight sections. When performance is only available for ISA conditions → fill in “0” for ISA deviation everywhere and copy the same data across all columns.

A couple of performance models have been added as an example.

As you can see below, the inputs into the flight plan are minimal now. Only a few inputs are required to plan a complete flight, the rest happens automatically.

I found an error which I will correct as soon as I can where the flight plan doesn’t extrapolate above the highest pressure altitude entered for climb and instead shows an error. I fixed this already, just need to upload to flightsim.to when I’m back home.
