First Lt. Jamie Leenman, a C-17 pilot with the 21st Airlift Squadron at Travis Air Force Base, Calif., operates Mission Index Flying (MIF) software on an Air Mobility Command mission laptop computer at Travis AFB on Feb. 15, 2012. To use MIF, aircrews input various aircraft and atmospheric parameters on a mission laptop at different intervals during a mission, with the software providing them with speed and altitude recommendations for maximum aircraft performance and efficiency.
