Increase the accuracy of ForeFlight’s time and fuel flow calculations by adjusting your aircraft’s climb and descent performance profiles based on observed performance. If you notice a consistent delta between your flights’ calculated performance and actuals using a given profile, you can bias the performance calculations to compensate for the discrepancy. Climb and Descent profiles support fixed positive or negative bias settings for both time and fuel, with increments as small as a tenth of a minute or pound.

ForeFlight Performance Profiles are available with ForeFlight Premium subscription plans.

Release notes

Dial in the accuracy of ForeFlight’s calculations even further with the ability to bias climb and descent performance profiles to suit your own aircraft.
Each aircraft type that supports built-in ForeFlight Performance Profiles has climb, cruise, and descent profiles based on manufacturer data, but previously only the cruise profiles supported biasing of time and fuel calculations. Now, both the climb and descent profiles also support biasing of time and fuel, giving you more control over how ForeFlight calculates these factors for every flight.
Tap into the Performance Profile list from the Aircraft, Flights, or Maps views to see a list of all climb, cruise, and descent profiles. Tap Details next to any of them to access the bias adjustments.
Specify a Fixed Time Bias in minutes and Fixed Fuel Bias in pounds using increments as low as 0.1 for each. ForeFlight will then adjust its performance calculations by the specified amount on all subsequent flight plans.
