Recently on a 738 flight flight from GVA, the take-off was aborted practically 1-2 seconds after full T/O thrust was set. The aircraft then braked gently and exited from the first taxiway and headed directly back to the T/O holding point. It then took off normally; the flight to destination was uneventful.
My question is besides faulty/spurious warning lights/indicators, what could have produced such a abort? Without the benefit of hindsight, could the decision to directly proceed to T/O after the mini-abort have been warranted?
