I think it should be pointed out to limp that the take off obstacle clearance cone used to calculate the minimum climb gradient required expands at approximately 10 degrees either side of the take off roll start position AND ASSUMES THE CLIMB RATE ACHIEVED AT T/O WEIGHT ON ONE ENGINE AT 75% OF MAX THRUST. Therefore an object that is way off the centerline and looks low can infringe said cone.
But you knew that didn't you.
Until the safe performance of the aircraft was confirmed the crew did exactly the right thing by not taking off.
The fact that they pushed on time in the hope of resolving the issue before reaching the runway makes good commercial sense.
Leave it to the professionals.
What is it with you professionals?
