I have a few questions regarding Large fixed wing aircraft air tests, Iam a purley helicopter man so please bare with me if these questions appear stupid.
On the large turbine engined helicopters I work on if we change an engine say we will carry out ground runs for vibration, leaks, operation etc, then all being fine will carry out an airtest for power assurance and max Ng. What Iam wandering is do you do this on large fixed wing ? or can it be done on the ground, the same for say a Servo control we will carry out a handling check, is this the same ?.
And when a 747 for instance has a major inspection and requires flight tests are these conducted at some minor airfield or from Heathrow or Gatwick persay ?.
