Commitment Point vs GEarth Map

Confidence for every short field departure. Commitment Point is designed to help pilots maintain greater awareness of their position during the take-off roll. By combining GPS positioning with runway measurements and heading information, the app provides a live estimate of your progress along the runway, including the remaining distance to your chosen commitment point and the runway end. Whether you're operating from a familiar aerodrome or a remote grass strip, Commitment Point has been designed to work entirely offline once your app has been installed, making it suitable for locations where an internet connection simply isn't available. On shorter runways, margins can be limited. Many pilots choose to establish a commitment point (sometimes referred to as a point of no return) before commencing the take-off roll. Commitment Point helps you monitor your progress towards that point, providing a clear visual and numerical indication of your position so you can maintain greater situational awareness throughout the take-off. Quick and simple to set up Getting started takes only a few moments. Simply enter the runway length, your chosen commitment point and the runway heading. If you don't know the runway length or heading, Commitment Point can help you measure them directly using your device, making it equally useful at unfamiliar airfields and farm strips. Before departure, the app calibrates your starting position using GPS before tracking your progress in real time throughout the take-off roll. Features • Live runway position tracking throughout the take-off roll • Remaining distance to your commitment point and runway end • Measure runway length if the published distance is unavailable • Capture runway heading using your device's compass • GPS calibration for improved positional accuracy before departure • Choose between graphical, numerical or combined tracking displays • Support for both metres and feet • Designed to work without an internet connection once configured Important information Commitment Point is provided solely as a situational awareness aid. It is not intended to replace proper flight planning, aircraft performance calculations, published aerodrome information, or the judgement and decision-making of the pilot in command. GPS accuracy, compass accuracy and device performance can vary depending on the hardware being used and the operating environment. Pilots remain solely responsible for the safe conduct of every flight and should always use appropriate performance calculations, approved aviation information and their own judgement when determining whether to continue or reject a take-off.
