In February 2002, a Gulfstream V underwent maintenance at a repair station at West Palm Beach Airport in Florida. The airplane was placed on jacks for a tire change. During the process, a maintenance tech disabled the weight-on-wheels, aka "squat" switches with wooden "Popsicle sticks" to simulate that the GV was in "ground mode" so he could access the Maintenance Data Acquisition Unit in the cockpit to troubleshoot a false overspeed warning problem.

Former Royal Air Force aviator O.W. "Wally" Epton, with nearly 17,000 hr. of stick time specializes in conducting functional check flights and training other pilots how to do the same in a responsible and knowledgeable way.

BCA contributor James Albright, who authors the "http://code7700.com" website, advises using qualified pilots and mechanics on functional check flights.
