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 It has been replaced by the General Aviation App.

Ratings and Reviews

Good start...


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...

Excellent app

Works quickly and easily. I was able to input the POH information and draw the CG envelope for the Cessna 421C in about 5 minutes. Updating the passenger/baggage loading takes less than 1 minute and the accuracy is better than my expensive mechanical graph & plotter. Completely customizable, you can add as many stations as you need and name them as you like.

Suggested improvements might include: the ability to input fuel as gallons instead of weight, and the app calculate the weight based on the fuel type assigned to each particular aircraft; zoom/expand the graph for a closer look; numerical display of the calculated CG.

Overall, an excellent app.


Flat Spin "heading out to sea"

I'm a CFII, retired Air Force pilot, electrical/computer engineer, and all around geek. I fly several different single and twin-engine aircraft daily and think this app is very useful and well thought out.

You can specify your weight & balance envelope and can continue to add points to outline various categories. With this, I can easily identify if I'm in the aerobatic, utility, or normal category. Enter your fuel in gallons or pounds, your choice.

To address previous comments, you CAN add and name your own aircraft, it is NOT limited to what's already on the list. Just use the update button, you can enter all the detailed parameters you want, like a unique aircraft name, v speeds, and a detailed weight vs CG envelope. You can also choose the weight VS moment chart if you prefer. And, yes you CAN sort your fleet to put it in your preferred order.

My only suggestion for improvement is to provide an option to lock certain values that don't change, like empty weight and arms.
