Runway overruns are one of a pilot's worst aviation nightmares. Recent change to some countries regulations require you to ensure you have a 15% buffer between your expected stopping distance based on the QRH figures and the actual runway length. You need a fast and accurate way to confirm that calculation you have done with the tables because it can be complex and you have to interpolate. You can make mistakes but this app, which uses the Boeing 737 QRH figures, is a backup to your manual calculation.

Using intuitive sliders and colour coded buttons you can quickly enter the parameters without having to resort to clunky keyboard entry of figures.

You have the option of tailoring which of the ten groups of variants currently supported by the app are available from the main screen thus eliminating the need for you to toggle past variants you don't fly. The app produces data for flaps 15, 30 and 40.

The app uses degrees Celsius, kilograms and elevations in feet as standard however you can toggle to Fahrenheit, pounds and metres. These options can be saved from the settings screen. When using other than the standard units there may be some small differences to the QRH figures due to rounding. If you find any significant differences let me know.

Before you buy this app make sure you operate one of the variants listed below (check the header of your Boeing 737 QRH Performance Inflight section). If you operate something different e-mail me a PDF version of the pages from your QRH and I will add them in. The variants are listed further down.

The app also provides Brake Cooling information for takeoff and landing. The brake cooling tables with its four way interpolation requirement is a nightmare to get right. This app allows for a quick cross check to make sure you haven't gone wrong.
Using the same data input as the landing distance calculation, the bottom section has two additional sliders to make this calculation. If you only want to do a brake cooling calculation then the colour coded labels (white vs light blue) show you which selections you need to make.
