Actually lazy people like myself still need to write up the load sheet. However I use an Excel file that does just all the multiplications and additions. CofG indexes are calculated also once you enter the passenger data distribution. We use calculators in the Flightdeck, this is a similar device with a bit extra. I do my own quick cross checks to make sure the weights and CG are ok. And the other crew does a cross check before final sign off. This pocket PC is approved by our CAA and it is safe provided correct initial data is entered in which is Passengers (Adults, Child, Infant) and baggage distribution in the Hold. I will most certainly keep using the load/trim program when flying with you and you can cross check whichever way you like to.
