Flapless approaches in a C172 require approximately 10 knots more than a flapped one (8 kts plus 1/3rd) - not a lot really. And yes there is more intertia and it is important to remember that this is the product of mass x speed squared. Looking out shouldn't be a problem, because if you are not big enough to see out you are not big enough to fly that type. But have you two above ever wondered why this procedure is practiced? And what speed do you reckon that a flapless approach should be done at?
How stupid of me! It's not like pilots frequently do flapless landings. They would practice this procedure for emergencies, like the flap motor or hydrolics not working or perhaps a water landing in a low wing aircraft?
As for the speed they land at I would have no idea. A 747 has a landing speed of about 140kts, so I'm guessing maybe 180-200kts without flaps?? I don't know.
I am just learning all this stuff so please excuse me when I come out with weird or stupid comments
