AlexL,
Instrument flying is just like VFR flying, except for having the outside horizon, you have an artifical one.
Instrument flying is about setting attitudes..and achieving a desired performance.
So for example in a descent on an ILS you will have a target pitch attitude, target rate of descent...maybe 600 fpm on an ILS, and a target airspeed. You will need to adjust you pitch attitude to the desired one, and adjust your power for the desired airspeed.
So for any phase of flight you should know the target pitch attitude, and power setting, if you set these initially, you can then adjust to refine fine tune your performance. Just like you do when flying VFR.
