Taxi2Parking;
That's why I asked. Always the benefit of the doubt... ;-)
sandbank,
...Surely you are not arguing the contrary?.
No, we're not arguing the contrary. The absence of your expected response does not prove your case. Besides sir...we are "first"...
A sign-off and departure is no more a "test flight" than the next flight you happen to take is - aircraft are operating under MEL (Minimum Equipment List) deferrals all the time. Is your car perfect every time you back out of the driveway? Would you take your car for a "test drive" after a bulb change? While there is very little opportunity to park, there is also a huge and unnecessary economic penalty for what you suggest. Now if you would like to triple your airfare and those of all other passengers, we will do a test flight first...
Most mechanical items on airliners can, with set conditions, be "deferred" for repair. There is a time limit and usually operational limits. It is authorized by both the manufacturer and the country's Transportation ministry. I hope this helps allay your fears.
