Yes, we agree in that a runway can be ICAO compliant and still the design might be daft.
In this particular case, an overrun of 149m would probably mean some damage to the undercarriage, while an overrun of 151m would probably mean complete destruction of the aircraft with no survivors.
So what I am trying to grasp is, in practical terms and taking into consideration the circumstances, whether 150m is "far enough" or "too close to the end of the runway".
I guess for the average passenger is probably not a big concern, because the probabilities of a fatal accident are still low, but for a company operating say 1,000 or 2,000 flights a year from there could be more affected (for instance if the probability of an overrun >150m overrun were 1/2,000,000 there would be a 1/1,000 chance of losing a plane per year only in that airport).
Any views or gut feeling?
