This is my version 1.0 "B737-800 LOADSHEET TRIM and BALANCE 3 ZONES PAX. This app was created to practice the manual load sheet. Fill out a load sheet is apparently easy, but when we have to do it quickly... This app is a good tool to practice and crosscheck. The aircraft model used is the B737-800 Y189. The app was designed for iphone`s, from 4 to 6 plus, and ipad`s, including ipad pro. The app is based on an original load sheet, so in the case of the iphones you will have to move with your finger the screen to get all over the page. bigger the screen less moving. in the ipad`s case the page is almost in full view. In the case of ipad Pro, the screen shows the page completely, without the need of moving it.
