F-35 Flight Test Update 8

By Sydney Carroll Posted 30 June 2012

The F-35 Flight Test Update in the Volume 27, Number 1 issue of Code One closed with Royal Air Force Sqdn. Ldr. Jim Schofield’s first flight, which, as it turned out, was also the program’s 1,500th flight. Since then, nine new F-35 pilots have qualified, bringing the total to forty-two pilots who have now flown the Lightning II. The growing pilot population has made significant progress testing external weapons on all three F-35 variants, accomplishing first flights with external stores, refueling inflight with external stores, and flying with asymmetric weapons loads. The team has also begun night aerial refueling of F-35 at Edwards AFB, California, and night flight testing of F-35B and F-35C variants at NAS Patuxent River, Maryland.

In the months since the last issue, the System Development and Demonstration, or SDD, test pilots have set new records for most flights in a month – 123 flights in March 2012 – and most test points in a month – 1,118 in June 2012. Through 30 June 2012, the F-35 test program had conducted 595 test flights in 2012 and accrued 4,830 test points.
