.. the last few posts represent where the discussion ought to be leading .. one of putting sensible and logically contrary viewpoints for the purpose of discussion and reflection.

Pilots need to have an idea of the real problems as opposed to SOP cant. Note I am not trying to belittle the SOP approach to things as such rigour, on the very great majority of occasions, provides us with a high probability of a successful outcome. The discussion ought not to be centred around what one might do on the day but, rather, examine the ins and outs of what should be considered in the decision making process which goes into the pre-roll briefing etc.

Some thoughts ...

No time to think - just act. Hence the repetitive practise in the sim...

This approach works well most of the time. However, we need to accept the consideration that there will be situations where the highly automated, rule-based, reaction may just not provide a desirable outcome. As is often suggested, it is not about absolutes .. it is about probabilities and the need to load the dice as much as one can in one's own favour ...

In critical circumstances, where the ideal is blurred by the reality of the real ... precisely this desirable skilset may just be the thing which puts the aircraft into harm's way ?

but what the hell does it mean? Is it Yes or is it No?

It means, for this question, that there are three domains of interest ..

(a) low speed black and white .. the probability of a successful outcome is loaded to the SOP stop case .. he who keeps going would be looked upon with critical gaze. This continues to be the case approaching V1 if the field length clearly is non-limiting with a comfortable margin ..

(b) an ill-defined, very greyish, area approaching V1 in limiting circumstances .. each case needs to be assessed separately. What is the best decision ? .. hard to say as the boundary conditions which constrain the decision making process may vary considerably.

(c) high speed black and white (assuming there is no secondary consideration arising which precludes flight) .. similar to (a) but loaded to the GO case.

(a) and (c) generally are easily seen as being rule based and programmed

(b) ... ? it depends ...

or he's been at the Fosters

.. only if there's nothing else on offer ... Hunter and Guinness for this lad by preference ..

We can not afford to treat a situation like this like robots.

That's the point I am trying to get across ...
