Got cleared for a visual approach in really bright sunlight and flew a curved constant aspect approach rolling out onto final at about 800' AGL with the aiming point in the right place and stable, on speed, very pleased with myself, and got a very agitated pilot in the other seat tell me I was high when the four whites became just about visible at about 400' (you couldn't see the lights before that because of the sun). They fairly quickly went one white, three reds, two reds two whites, one white three reds and then we landed in the right place at the right speed. I often fly with a logger and we analysed the points afterwards and I had flown a reasonably accurate 3.5 degree glide path with no change in power setting at all from 3500' until I closed the throttles at about 40'. My aeroplane will comfortably fly an approach up to about a 4 degree glide and there are procedures which allow an approach path up to 4.5 degrees. In my opinion, picking up and adjusting to the lights at approximately 400 feet would have destabilised the approach or at least risked that but flying a clearly stable visual approach (exactly as if there were no lights at all or they were out of service) was fine. To answer the original posters question, surely you can't simply fly three whites and a red or three reds and a white to fly a three degree approach in an aircraft thats got a different eye height to what the lights are set for. If you fly 2R2W you are on the path the lights are set for and if the eye height is different you will touch down deep or short (probably deep as they should be set for the largest type). If you fly a different combination, youre on a different path. Isnt it as simple as that?
