RAT 5
Let me analyse what you say:
1. On approach, you see the speed dribbling back (or increasing) and you 'feel' the T/L's opposing the drift, or you do it yourself with a suitable nudge. It's instinctive. You see, you feel, you hear. First it is not instinctive but habitual and habits can be unlearned or learned. Second suitable nudge is not manufacturer's recommendation. Also it doesn't ensure that N1 is increasing. In Airbus also you can nudge forward against manufacturer's recommendation and off course you see and hear.
2. They don't even look at the ND never mind the N1% gauges IMHO they are as important as a flight control imparting energy to the a/c. Give it the wrong amount and it ain't going to do the job. You can anticipate the speed will decay or increase.
N1 is a reference. The basic parameter that attracts you to N1 is speed. The anticipation of decay or increase of speed doesn't take much as speed trend arrow does it for you. The problem is not looking at N1 gauge but not looking at the speed at all till the point of crash experienced and inexperienced alike.
3. So my question; with non-moving T/L's you have to be more vigilant with the N1% and the scan is a very visual only affair. Do you find this instinctive and are you aware of any more work load?
As long as one knows how to manage trend arrow you don't need any more vigilance. Maintain correct pitch and manage trend there is absolutely no problem.
