If you can fly by datums (attitude) it is very rewarding as you lose a load of old habits such as trying to chase speed/height unnecessarily and your flying suddenly becomes cleaner and more accurate.
This thread has highlighted the fact that many people may be taught to fly datums initially, then develop the habit of flying on instruments and it's not picked up on by instructors or even the student who can't figure out why their flying isn't as accurate.
Something to think about....
Could you fly accurately e.g. turn in the circuit, fly finals/final approach in the event that you had a total instrument failure? Could you pick out the say correct visual picture for say, 70kts with land flap comapred to 75kts with TO flap on the finals turn without stalling/dutch rolling?
EDIT: Forgot to add:
Not really dutch roll in an SEP, more of a roll susbisdence feedback (or so I was corrected by my geeky engineer of a friend....
)
