ACB and FM Form

If you have several Check Books for a particular plane, they will be displayed in the selection list. Tap on the necessary one in order to confirm and store your choice. The active Check Book is always highlighted in blue color.

Use Button “Choose Aircraft Flight Manual” to open a dialog and select your .pdf previously stored on the device memory. After that the document can be displayed on the screen #3 of “Performance and Limitations” Form

Weight & Balance

The App has a simple form to check your Weight & Balance calculation and visualize the results.
Calculation is based on the performance and limitation data defined in the Web App and stored in your Database.
You can choose a fuel type and manually change its density and fuel consumption per hour.
Fuel in tanks are to be input in Liters or US-Gallons
WARNING: This App is NOT CERTIFIED as official pilot’s aid! You as PIC is solely responsible for correctness of all your data, flight preparation, in-flight procedures etc.
WB 1
In the W&B Form you can switch between input in Si or Imperial format. The values will be automatically recalculated. Please note that the density of the fuel might vary depending on weather, type of paricular fuel etc., so the represented numbers shall be re-checked
The App performs some checks automatically (i.e. calculated TOW > MTOW according to the flight manual) and issues warnings and errors.

Once calculation is completed, the results are represented graphically in the following form
WB 2
For better readability X-Axle is scaled with factor 100 due to representation in Si (mm).
The blue point reflects the CG point with fuel once red triangle represents the CG point w empty tanks - so the line shows you the change / move of CG point during the flight due to the fuel consumption.

NOTE: CG Envelope is based on the data provided in the Web App and should be store in format (X1;Y1)(X2;Y2)…(Xn;Yn) from the left bottom point of the envelope to the right bottom one in order to be displayed correctly. For our example the correct string is (in Imperial):
Main Envelope: (33;1700)(33;2250)(35.5;2700)(40.9;3100)(46;3100)(46;1700)
Landing Limit: (38,9;2950)(46;2950)
If the envelope is not provided or contains errors, the App will draw the CG points only.
