GroundRollCalc

Real-time takeoff performance, runway awareness, and GPS-based rollout tracking—designed for pilots who want immediate insight into aircraft performance.

Key Features

Ground Roll Estimation Calculates expected takeoff ground roll based on: - Aircraft performance data - Weight and loading - Wind conditions - Density altitude - Runway slope and surface - Runway Visualization

Graphical runway display with: - Estimated ground roll marker - Safety margin indicators - Remaining runway awareness

Live GPS Mode (Optional) - Track actual takeoff roll in real time - Compare real-world performance to predicted values - Detect deviations from expected performance

Aircraft & Airport Management - Store multiple aircraft profiles - Manage airport and runway data - Customize inputs for accurate calculations

Built for Real-World Flying - Designed for clarity and speed in the cockpit - Clean interface optimized for iPad use - Focused on practical, decision-support information

Important: GroundRollCalc is a supplemental performance tool and is not a substitute for approved aircraft performance data, POH/AFM guidance, or pilot judgment. Always verify performance calculations and operate in accordance with safe aviation practices.

Data Sources Airport and aeronautical data may include publicly available datasets such as FAA and openAIP sources.
