Bonanza Performance computes all the useful performance numbers for flight planning for Beechcraft Bonanza aircraft with options for turbonormalizer and tip tanks. It includes calculations for takeoff, landing, climb, cruise, descent, instrument procedures as well as emergencies. It also includes an interactive hold calculator, a risk analysis tool, and an emergency glide distance calculator that handles head and tailwinds.

Bonanza Performance is also available as a WebApp (an App that runs in a browser) that runs on a variety of platforms (PC, Mac, tablets, phones). The Cloud Sync feature allows flight planning profiles entered on any device to be synchronized with your other devices when connected.

Bonanza Performance is a free, open-source development effort and has Apps and WebApps for other aircraft. See for complete details.

STOP right now and get this app!

I spent a few weeks using this app before writing a review. I was pretty blown away how useful this app is. I recently purchased a Bonanza and have a very difficult time reading the spaghetti charts in the aircraft’s POH to calculate performance. After using this app my level of confidence has gone up dramatically. The developer put a lot of time not just into designing the app from a functionality perspective, but also from a user experience perspective. It is very easy to use and gives you a ton of information. And, it is fun to use since the performance output is often in a visual or is color coded.
Thank you so much for the work you have put into building this.

Thank You!

I just purchased my first airplane (I’ve rented for years). I never thought that I would own a Bonanza, but here I am. This app has proven to be a tremendous value in getting to know my aircraft, and an even bigger value as a safety resource. My wife was nervous about the plane’s reputation as a “doctor killer”, but after showing her the resources available, especially this app.. (as well as...the Bonanza Society, CSOBeech, and BeechTalk) she is much more comfortable with the plane knowing that we have years of experience, wisdom, and support available just for the asking. Thank you Steve! The app is excellent and improving with each update.

Nailed it

This app get all the pertinent information together. A simple layout and great overview of weight and balance that is crucial for Bonanzas, the developer nailed the layout to include everything pertinent.
Seldomly you get an app that just does everything right from the get go. It loads the data as you type.
Here airplane performance and weather immeadeately are loaded and give runway analysis and route fuel burn.
Simple and correct in its view its a must have for the Bonanza pilot as a quick reference.
