  3. -Tap on the name on the name of the aircraft you wish to edit (8)..

  4. -Tap on the item you wish to change (10, 11 or 12). Enter the new data. If this is the currently selected aircraft, the W&B will be recalculated immediately.


  1. 7.If I update iBal, will I lose my aircraft?

No. Your aircraft list will not be altered after your first install of iBal. This also means that new sample  aircraft that might come with a new version of iBal will not be added to your aircraft list. Nevertheless all new types will be available in the type selection menu if you create a new aircraft.


  1. 8.In iBal, how do I delete aircraft?

When you first install iBal, it comes with a set of sample aircraft for you to experiment with. When you are familiar with iBal, you will probably want to customise the aircraft list to only include the aircraft you fly. To remove the unwanted aircraft:

  1. -On the Select Aircraft page (6), rub your finger side to side on the aircraft you wish to delete.

  2. -A Delete button will appear.

  3. -Tap it.

You can then follow the instructions above for adding your own aircraft.


  1. 9.In iBal, how does the % fuel tank entry work?

Some types of aircraft (notably Eurocopter AS355) have multiple fuel tanks and a fuel gauge for each tank calibrated in % of total fuel load in the cockpit. On those aircraft you can enter in iBal the fuel load in each tank as a percentage % of the total fuel load.

(The behaviour of the % fuel load entry changed in iBal 1.11. Previously it was available for all aircraft and showed the quantity in that tank as a percentage of the maximum possible for that individual tank).


  1. 10.In iBal, can I add my own types?

iBal comes with a large set of predefined aircraft types. You can set up your copy of iBal to have any number of your own specific aircraft, where each aircraft can be any of the predefined types. You can easily remove the sample aircraft (see above) so only your own aircraft are listed. You can have multiple aircraft all with the same type or with different types. You can add custom load stations to your aircraft. But you can’t change the set of available types.

If you need iBal to support a new type, or new configuration of an existing type, email ibal@iwizwheel.com with the complete flight manual (including all limitations and weight and balance information, manufacturers data etc) in electronic form, as well as a photograph we can use as the default photo (3/4 view, neutral background, rotors stopped). We will consider it for addition.

If you want to have iBal customised to suit your fleet, please contact us at ibal@iwizwheel.com


  1. 11.In iBal, can I change the fuel specific gravities?

Yes. The SG for each type of fuel can be changed in the iBal Settings. On the iPhone home page, tap on Settings, then tap on iBal. Tap on the item you wish to change and edit the value. Values are in kg/l. The defaults are commonly used values for those fuel types. Some other commonly used values are:

Jet A1 @ 60°F @ 6.8 lbs/usgal = 0.815064 kg/l

Jet B  @ 60°F @ 6.5 lbs/usgal = 0.7788716 kg/l


To convert lbs/usgal to kg/l, multiply by 0.1198264 (CRC Handbook of Chemistry and Physics)


  1. 12.In iBal, How do I enter passenger names and Flight Details for the manifest?

You can enter optional passenger names for each seat location. On the Load page (2), tap on the seat location (13). Enter the passenger name in the ‘Optional Name/Description’ field. Each passenger name will appear on the Data CG solution page next to their load station.

You can enter Flight Details for the proposed flight. On the Load page (2), tap on the Information icon at the top right (15). On the Flight Details page, some or all of the flight details. You may want to include the Route, ETD, ETA or other relevant or important details. This text will appear on the Data CG solution page near the bottom, under Flight Details.

If you Send the Data page to an email address, any passenger names and flight details will be included in the emailed solution. You can use these features to remotely document the W&B, Passenger manifest and flight details for every flight you make.


  1. 13.In iBal, How are changing fuel CGs shown on the CG graphs?

On the Longitudinal (3) and Lateral (4) graphs, and in the Solution spreadsheet (5), iBal shows the CG positions of the fully loaded and empty fuel loads with a line joining the two. It also shows the CG positions of any intermediate loads that are outside the fully loaded and empty fuel loads. If there are no intermediate loads that are outside the fully loaded and empty fuel loads, it will show a single straight line. It does not show the CG of every intermediate fuel load, only the ones that are ahead of or behind the full and empty loads.


  1. 14.In iBal, how do I delete Custom Load Stations?

To remove the unwanted Custom Load Stations:

- On the Edit Aircraft page (9), scroll down to ‘Custom Load Stations. Tap it.

  1. -On the Custom Load Stations page, rub your finger side to side on the station you wish to delete.

  2. -A Delete button will appear.

  3. -Tap it.


  1. 15.Will iBal run on iPad?

Yes. Any iPhone app (including iBal) will run on iPad.


  1. 16.How does iBal Aircraft export and import work?

Exporting and Importing of Aircraft was added in iBal version 1.23. It allows you to send the configuration of any aircraft in your aircraft list by email. People who receive the email on their iphone and who have iBal installed will be able to import the aircraft into iBal. iBal uses the Mime Type application/x-ibal-aircraft to export and import aircraft definitions.


To send an aircraft definition:

  1. -On the Choose page (1), tap on the current aircraft name, get the aircraft selection list (6)

  2. -Tap on Edit (7)

  3. -Tap on the aircraft you wish to send (8)

  4. -Tap on Send (23)

  5. -Enter the recipient email address.

  6. -Tap on Send


To import an aircraft definition:

  1. -Have someone email you a definition as described above to your iphone

  2. -Open the email

  3. -Tap on the ibalaircraft attachment

  4. -Tap on ‘Open in iBal’

  5. -iBal will opened with the new aircraft added to your aircraft list and selected as the current aircraft


  1. 17.Can I put iBal Aircraft Definitions on a web page?

Yes, provided the web server is configured to deliver the .ibalaircraft files with a ContentType of

application/x-ibal-aircraft. This might require you to add something like this to your web server configuration:

AddType application/x-ibal-aircraft .ibalaircraft

This will cause any file with the suffix .ibalaircraft to be sent with the correct ContentType. When such a file is accessed with Safari on your iphone, you will be able to ‘Open in iBal’. This will add the aircraft definition to the end of your aircraft list and also selects it as the current aircraft.


  1. 18.How do I change the units displayed on the CG spreadsheet and the graphs?

iBal uses the units of the BEW for an aircraft to determine what units to use on the CG graphs and Data pages. To change it, edit the aircraft, change the units of the BEW to either Pounds or Kilograms and the graphs and Data pages will change to suit.


  1. 19.Are there any online help or discussion groups for iBal

Yes: http://groups.google.com/group/ibal-help
