dharmesh4,
Notwithstanding, and certainly not anticipating, any decision from forum moderators, it is vital, I think, that you follow Genghis' advice and get some quality time looking at the pilot's, and air trafficker's, environment before asking for detailed information.
We have to build our situational awareness using the tools we have available. Apart from our own physiological sensors (eyes, ears, hands, feet), we have the instruments that exist, and the places where they exist, in the aircraft we are flying.
Are you aware that the majority of the GA fleet of aricraft is elderly? Have you looked at the layout(s) of an instrument panel? (There are, at least, photographs available in various places on the web.) Those of us who hire, rather than own, aircraft have to cope with varying instrument layouts in the same type of aircraft.
There is not a great deal of cash around to invest in sophisticated instrumentation displays - or that, at any rate, pertains for the majority of GA pilots. Yet we use the instruments we do have in order to gain the kind of SA we need to make ourselves as safe as we can be, and to play our part in cooperating with all the other users and stakeholders in our airspace to contribute to the general level of safety. (A long-winded way of saying that safety is a mutual endeavour.)
A well-researched, well argued, cogent study which is not congruent with the real situation in this field is as useless as poor research. There are opportunities to connect with that real situation - it's merely being suggested that you avail yourself of those opportunities.
