Human Factors; Procedure
Standard approach to LOM. I made positional report 10 miles and then 5 miles from the airport. I was aware of [Pilatus] on straight in 5 mile final to Runway 6 and announced my intentions to be number 2. Shortly thereafter; I heard a report of a Cessna in the left downwind traffic pattern for Runway 6. I was approaching the 45 for left downwind and anticipated I'll be number 3 after the Cessna. I slowed down as much as I could to maintain separation and extended my downwind with the Cessna in sight turning final.Here is where I was caught off guard. The Cessna was much slower than I expected and had taken a longer downwind leg than what I would consider usual. Nonetheless; I kept a comfortable separation and planned on a shortfield landing as I was slowed less than standard approach speed. The Cessna landed and taxied all the way to the end of the 3;700 foot runway. There is a turnoff at 1;200 and 2;400 feet. I landed as the Cessna was slowly taxiing to the end of the runway. I was able to turn off at the first intersection at 1200 feet just as the Cessna was turning off the runway at 3;700 feet. My landing was well within my abilities and I was comfortable with the separation and was prepared to go around if I felt it was not safe. When I flew to Oshkosh for the air convention; the separation was much tighter.In reviewing the FAR/AIM manual (Aviation Reference Book); I was not aware there was any mandatory requirement that a plane must be off the runway before you touch down. I will definitely be more conservative with my spacing for landing.
GA pilot mis-judged distance from aircraft landing and landed on runway before previous aircraft was clear of runway.
