Obstacle Analysis

At the heart of ForeFlight Runway Analysis is the complex Obstacle Analysis, which incorporates terrain and obstacles into its max takeoff weight calculations to guarantee clearance.

Engine Out Procedures

Plan with the default Straight Out procedure or optimize your weight margins with RNAV procedures developed by ForeFlight's team.

Additional Obstacles

Manually add temporary obstacles from NOTAMs to ensure the calculation incorporates all potential hazards.

Safety-Enhancing Warnings

ForeFlight provides a number of warning and error messages to let you know when the calculated results exceed the aircraft’s or runway’s limits, including aircraft-specific alerts for invalid takeoff or landing configurations or overweight warnings.

Emergency Return Included

A fully-featured Landing Analysis capability built into the Takeoff Analysis allows you to evaluate Return-To-Base scenarios using different runways and aircraft configurations to determine the best course of action in case of an emergency. ForeFlight provides warnings for exceeding brake energy or weight limits to help you determine the risks of each scenario.

3D Engine Out Procedures

Familiarize yourself with an airport’s EOPs before takeoff using interactive 3D terrain and aerial imagery. While viewing the Runway Analysis Takeoff page or the list of Engine Out Procedures, tap the 3D View button next to any EOP to open it in 3D.

Landing Factors

Easily comply with your Opspec’s landing allowance requirements by setting a Landing Factor to be multiplied by the calculated landing distance. ForeFlight provides preset factors corresponding to 60% (1.67, 1.92) or 80% (1.25, 1.44) of usable runway requirements, and also supports entering a custom factor.

Easy Scenario Planning

Rest easy when plans or conditions change. ForeFlight automatically pulls weather data from the most recent METAR, TAF, MOS, or general forecast at each airport to dial in performance calculations, and all environmental factors are user-editable for easy customization. See how your takeoff margins respond to a 10° OAT rise, or check climb performance from a balked landing in icing conditions.
