What a/c you flying? Obviously the speeds are dependent on that. In the pa38 pretty much everything happens at 70knots so its easy to remember. I'm flying the pa28 and speeds for normal approach are 65 and then 60 over the threshold. Flapless we use 70 on the approach, glide we use 75 app speed. Like you say the attitudes are all different too. The flapless is a very shallow approach and the glide is pretty steep.
For the nav exam I needed a calc for all the little calculations that are needed, rod, fuel burn, pressure differences etc. I can do em all on a piece of paper but it would take 2 seconds to use a calculator so I didn't really see the need to not have one. I use the whizz wheel for the wind side, plus I use the other side for working out conversions, TAS, density altitude, etas etc. I've never used it to just multiply numbers together. oh well, I passed lol.
