Bonanza Performance computes all the useful performance numbers for flight planning for Beechcraft Bonanza aircraft with many third-party options such as 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 http://pohperformance.com for complete details.

What's New in Bonanza Performance
4.4.8
November 30, 2024
- Allow generic IO-550 upgrade with Osborne tip tanks on V35.
- Fixed data source for generic IO-550 upgrade to indicate G36 POH data.
- Fixed a bug in the takeoff roll adjustment for runway slope.
- Updated the airport database.
I can’t stress the title of this review more. I have flown Bonanzas for over 3 decades. Trying to calculate performance using the charts in the POH is difficult and highly error-prone. This app tailors the performance to your specific make/model/configuration. It automatically corrects and adjusts for conditions based on the most current METAR. The risk analysis feature is powerful. I never consider flying (even by myself) without consulting this app first. It is very user-friendly and easy to navigate. The color-coded performance information is very helpful. I’m shocked that this app is free.

Response from developer
Thank for your 5-star review and the complements. The app is free and the source code is published to foster a community effort. Several Bonanza owners helped contribute to the app by digitizing and encoding the performance data.
