MilACARS is a desktop client that talks to the site over a documented REST interface. It sends live telemetry and the final PIREP.
It scores your flight as you fly it
MilACARS downloads the airline’s scoring rulebook and scores the flight as it happens, so the pilot watches the judgement forming instead of receiving a verdict hours later. Read the rulebook.
Every landing is a curve, not a number
The client hands over the full approach profile: a sample every fifteen seconds from 3,500 ft radio altitude, tightening to one a second in the flare. A go-around produces two approaches, and both are kept.
