Went tech not so long ago and engineers were depatched from STN to fix it.
But dont go tech very often because the airplanes are so well maintained.
Remember every FR aircraft sits on the ground at every base from 2330 until the first departures about 6am so the engineers have ample time to fix snags.
FRs operation can only work if the planes are well maintained and dont go tech. They are well maintained and invariably they dont go tech.
Believe it or not at a meeting with MOL after 9/11 we all assumed we would be entering night flying business to get better utilisation of the a/c but MOl dismissed this idea for the maintenance reasons above. Think we were all shocked and relieved at his response!
Take it you have done a FR sim check to qualify your statement or is this an uneducated guess?
