C-130 preTOLD for iPad
C-130J preTOLD is a takeoff and landing calculator for iPad. It is used by pilots and flight instructors in the U.S. Air Force for use with the Lockheed Martin C-130 “Hercules” cargo airplane. The application was originally developed in 2014 and is actively maintained and used by pilots and flight instructors around the world.

I work with Elite to design the user interface for preTOLD. The purpose of the application is for pilots to think through flight scenarios that have varying weather or runway conditions. It is important that pilots are able to quickly switch between these scenarios and compare them to each other. Our interface has dedicated buttons to create, save, and view saved flight scenarios. By putting this functionality at the top-left of the screen, users of preTOLD don’t have to dig into menus or browse files to open, modify, and save their flight plans. As a result, the user feedback we get from pilots and flight instructors is overwhelmingly positive.
Development
I implemented our design using the Xamarin.iOS tools. We chose Xamarin because Elite had an existing Windows .NET codebase. Xamarin enabled us to re-use the exact same calculation code across both Windows and iOS. To facilitate even more code sharing, we designed the data model using the ViewModel design pattern. This enabled us to share some UI logic (such as input validation) and has made testing and general maintenance much easier.
One of the major features of preTOLD is the ability to export your flight plans as a PDF “TOLD Card”. The TOLD Card is a standardized way of displaying and sharing flight information. Using the application PaintCode, I created the TOLD Card as a custom view. This enabled us to easily switch between light and dark color schemes, export the TOLD Card to PDF without a third party library, as well as enable other custom interactions.
Developed with C#, .NET, and Xamarin iOS tools.

preTOLD is a flight planning application for pilots of the Lockheed Martin C-130J cargo airplane. C-130J preTOLD is the only TOLD planning tool approved by Lockheed Martin for technical accuracy and overall functionality. It takes the TOLD planning capability of the Mission Computer (MC TOLD) off the flight deck and into the hands of crew members and planners. C-130J preTOLD has been validated against MC TOLD in partnership with Lockheed Martin. For crew members, C-130J preTOLD adds pinpoint accuracy and confidence to preflight mission planning and enables operators to utilize the full capability of the C-130J every day.
Developed with C#, .NET, and Xamarin.
