Telemetry Room Helps Engineers Track G600 First Flight
As the Gulfstream G600 soared through the skies for its first flight, a ground-bound team of flight test engineers tracked the aircraft’s every move.
Their tool of choice?
Gulfstream’s expanded and enhanced telemetry room, a space dedicated to monitoring aircraft parameters to ensure tests are going as planned.
Miles away from the aircraft’s action in the sky, engineers were able to see the G600’s attitude, position, speed, vibrations, temperatures and pressures, as well as myriad other flight condition and system operating parameters. They were also able to communicate with the crew.
“The telemetry room is used for high-risk testing to allow engineers to monitor the data from the plane for safety of flight,” said Brian Ehret, principal engineer in Gulfstream’s Flight Test Instrumentation Department. “As part of that monitoring, the crew on the ground can call a halt to a test in progress to look a little closer at the data and make a determination about whether it’s safe to proceed.”
The room can be subdivided into two smaller spaces to track two airplanes flying simultaneously and can receive a 10 megabit data stream, which is just a small portion of the data recorded and measured on the aircraft.
It gets the most use during the early stages of a flight-test program, such as on the first flight and during flutter, loads and dynamics and field performance testing.
