CFI Tools Weight and Balance
PURPOSE: The Weight & Balance App is used to save weight & balance information in a simple format for easy reference.
When you fly many airplanes it can be difficult to keep track of the weight & balance for each one. But of course it is critical to perform these calculations before each flight and to verify the results.
The iPhone is a terrific platform for keeping this information.
This App makes it simple to maintain this information for a fleet of training airplanes or even for a single airplane.
Check out the screenshots to see how simple this process can be.
The W&B data is fully customizable. You can enter the specific data for your airplane. There is no limit on the number of stations.
You can create an airplane using a generic version of one of several popular GA aircraft including Cessna, Cirrus, Piper and Diamond.
The CG can be plotted in inches, as in the Cessna, or in moment as in the Diamond.
The CG is plotted with both full and empty fuel so you can see the range of CG's that may be experienced during the flight.
Also shown is the "Excess Capacity" - the difference between current weight and Max Gross. This is a number I often need to know if a student wants to bring a passenger along for the flight.
The Moment Arms and the Envelope are fully updatable and can be customized to fit your airplane's numbers.
CAUTION! Please consult your Pilot's Operating Handbook or Approved Flight Manual for complete Weight & Balance Information
DO NOT! rely on the generic W&B information provided here.
PLEASE NOTE: This App has been retired but remains in the store for existing customers and very limited maintenance. It has been replaced by the General Aviation App.
About CFI Tools
I'm a Pilot and a CFI. I build these iPhone apps and other software for my own use.
Some other pilots saw them and said "Hey you should sell those".
So here they are for sale. I hope you enjoy them. Any suggestions for improvement or new apps are always welcomed. Have a good flight.
- A few UI screen size updates
- Please note, this App has been retired for a couple years now, that means there will be very little or no maintenance. It has replaced by the General Aviation App, please visit http://www.cfitools.com for more information on the GA App.

Good Start, Needs Work
There don't seem to be many dedicated W&B apps around. This looked like the best, so I bought it. And maybe it is the best, but it needs work.
First, as previously mentioned, it is too easy to change important numbers like moment arms. They are simply data fields like the weights. This is a safety issue.
Second, also a safety issue, the app does no sanity checking of input. It will happily take 300# of fuel at a zero moment arm. The input for fuel is a little goofy, too, with the choice between entering #s and gallons a little clumsy.
Finally, the airplanes in the "fleet" are listed in the order they were added. No sorting options. Well, when I get done I am going to have a dozen airplanes entered and every use of the app is going to begin with a hunting expedition to find the tail number I need to work with. Give me some sorting options please.
I look forward to Ver. 2 with a little more thoughtfulness in the UI.
Where is a 152?
Bought the app. No profile that I can find for a 152.
Update: Increased to 4 stars. Great job on the copy function - it is sooo much easier now - thank you!
Only suggestion left would be a simpler screen for adjusting just the weight which are subject to change on every flight.
I like the look and feel of the app - it's a good start - but - it could use a few improvements... As per the previous comment - we need the ability to "copy" an aircraft as we may have several loading configurations for the same plane... It's very tedious to keep entering all the same information over and over for multiple configurations of the same plane... An additional field to identify the load configuration would be helpful... I would also suggest a simplified load screen where you can only change the weights at each station... Once the profile is built - "Station" and "Mmt/Loc" should be locked in - as it rarely changes and it is very easy to click on the wrong field and erase the required information...
With Family Sharing set up, up to six family members can use this app.
