Hi

Er...um...please sir...
(puts hand up)...do we count sir?
Haven't done a derated take off in years!

We may get there. We have company issue palmtops with, amongst other programs, all our T/O Data loaded in. They work very well, and are extremely useful, but currently (!) are only approved for use as a cross check, after all manual calculations have been completed.
The primary T/O data source is still the T/O performance manual.
The load sheet and trim program
is approved for use (though we are still required to produce printed or written copies) and is a godsend!
