Running Aircraft Engines
i was on a recent flight from manchester when a technical problem forced the crew to divert to a remote parking area shortly after taxying out ,we spent about thirty minutes there whilst a couple of engineers worked on one of the engines, the crew then anounced that hopefully the problem had been rectified and that a short engine test was required , however as the engine started i noticed the crew were in the galley area chatting to one of the engineers while the other one ran the engines!,is this normal surely the only people qualified to do this are aircrew, im suprised engineers can do this with passengers on board ,surely this isnt normal procedure?
