Recommendations:
After creating your Weight and Balance list, it will be saved in the Downlaod folder on your phone. I recommend that after creation you move the file to a cloud (Dropbox, Google Drive, etc) of your choice so that when ANAC asks for your weight and balance you can access it from another device. Remembering that the file is saved with the day, month, year, daily number and page number, thus facilitating the location of your Weight and Balance.
Remembering that ANAC requires you to have the weights and balance with your aircraft's passenger list for 1 year.
