Why would it be so hard for the patter to be "flock of geese, go around" or "aircraft below aproaching, go around"??
If the intent of CRM is that BOTH crew members are aware of situations so understand and work co-operatively - why would you abandon that and kneejerk a reaction at 1500' on the perception of one crew member only without some explanation??
Do you believe in CRM - or not??
Seems a tad contradictory.
Please remember I am only highlighting a situation where most appear to say they'll react to the call at ANY altitude, I suspect ops man's probably state "on final approach" or similar which can be anywhere below 6,000' on some ILS's, in some countries, the question of whether you're in IMC or using the ILS as tracking in visual conditions probably irrelevant to the wording in the ops manual regards a "go around" call.
Don't see a problem with the "kneejerk" comment as accurately describes how you have stated you'll react in ALL circumstances.
I just think kneejerking is counter productive when you have enough time/altitude to ask "why?" if no explanation was provided, just a "go around" statement.
Believe the paramaters and criteria could be far better defined than at present which seems to upset some.
Cheers.
