LR-JET Weight & Balance speeds up and simplifies the process of weight and balance calculations for Learjet models 31A, 35A, 36A, 55 and 60. Whether you fly a single aircraft, multiple aircraft, or aircraft that have different configurations, you can store a separate profile for each aircraft and configuration. Configure the profile to match your aircraft, then enter crew, passenger, baggage and fuel weights. Aircraft loaded weight, center of gravity, and forward and aft CG limits are displayed in inches or percent MAC.

DON'T BUY no support

I used to use this app regularly. However with the latest iOS update the app no longer works. Furthermore, the email listed by the app developer does not work. I wonder where the money goes?

Developer Response ,

Well, that's embarrasing. In the process of changing mail hosts, I forgot to set up the support address, and I don't get notified of app reviews, so I didn't realize there was a problem. I apologize to all those who tried to email for support and got their messages bounced back to them. I'm still here!

Exactly what is needed

Without looking at any documentation within a few minutes this app was easy to navigate & use. I fly multiple aircraft with special equipment & this app allowed me to store airplane specific data for each one. Now it takes less than a minute to easily & confidently compute wt & bal. Last minute changes take 10 seconds. A "must have" for any LR pilot.

If you are a crusty, flea bitten Lear 31, 35 or 36 driver you need this app!

I took this app for a spin today and once all the numbers are put in it works great, lasts long time. It is very user friendly! A must have for anyone who flies Lear 35's, 36's and 31's.
