Initially, the expense aspect for our airline was already covered. Hank Puteck, one of our astute pilots with a computer science background, realized that, like me, most of my colleagues traveled to work with their own personal laptops. He converted our entire 777 operating manual into PDF form. He presented the PDF version of the manual to our then VP of flight. Why not make all reference manuals available for electronic download to those pilots who choose the option? Hank was given the green light as the project manager. The FAA approved almost immediately. The caveats were that a spare battery was required, the laptop operating system must be compatible, and the hard drive must have a given minimum storage capacity.
