Dan. Agree with your thoughts. I am wary, however, of teaching a call out of specific items that do not apply to the aircraft type.
For instance, it is almost universal among flying schools to teach student pilots to say out aloud "Wheels down and locked" (as part of the before landing checks) on fixed gear aircraft, on the somewhat dubious premise that it is a good habit to get into because they may one day fly a retractable.
This despite the fact that before a student is considered competent to fly in command of a retractable gear aircraft, he must have completed a specific course of training and have been certified competent.
It is during this training course that the specific drill of checking the landing gear down for landing is brought into action. As well as confirming gear up and locked as part of the after take off checklist.
The problem with teaching a fictitious drill for a fictitious operation (on a fixed gear type) is that in times of stress, there is a risk of reverting to the habit of calling gear down and locked - or pitch full fine without taking the appropriate action when later operating these special design feature types.
Not forgetting that the same student may one day fly an amphibian where the before landing checks might be "Landing gear UP and locked for a water landing!"
Interestingly, one very rarely hears of a fixed gear aircraft checklist which, while calling for gear down and locked on the before landing checks, calls for gear up and locked as part of the after take off checks.... A little inconsistent, one could argue.
Recently, the Australian Transport Safety Board advised that despite a thorough search through its data base on incidents involving wheels up landings, there was no statistical data to confirm that calling gear down and locked, as part of the before landing checks on fixed gear aircraft, lessened the chances of an inadvertent wheels up landing on a retractable type.
