Procedure; Human Factors; Aircraft
I set my Aspen [EFIS] for the ILS 10 approach. During the first approach I was turned in fairly fast and had excessive speed. I disengaged autopilot; but wandered too far left on localizer. Tower Controller issued command to turn left and climb and contact NorCal for a new approach. As I was cleared for the second approach I inadvertently did NOT reset the approach procedure on the Aspen. (Note: I did not recognize this problem until later after I was on the ground and rethought the whole incident.) During the second approach as I was turned on the localizer the left/right indicator wandered and the back course indicator showed periodically. During the confusion I wandered left of course and Tower issued altitude alert for 600 feet -- but I was at 1;200 FT. I broke out shortly thereafter and landed. Tower had me phone NorCal. Supervisor asked what happened and I said the confusion from faulty indications on Aspen which I would check with my avionics shop (not yet realizing my Note above). Supervisor asked if I had any complaints about air traffic personnel and I answered 'no.'
CE210 pilot reports being issued missed approach instructions after being turned on to the localizer with excessive speed and not being able to maintain the localizer when the autopilot is turned off. The second approach again results in localizer deviations; this time due to the EFIS not being reset for the approach. A successful landing ensues after breaking out.
