The most challenging stage of the takeoff is carrying the speed forwards from the inrun with sufficient height over the "knoll", and achieving the correct trajectory down the hill. The knoll is the highest point of the hill itself, from which it begins to slope downwards. On modern ski flying hills the table is placed considerably far back from the knoll, so as to reduce the steepness of the flight curve. Skilled athletes are able to aggressively 'snap' into the transition so as to clear the knoll with ease, thereby allowing them to focus completely on using their flying technique to maximise distance further down the hill. All athletes have greatly varying flight curves, each with their own advantages and disadvantages; a flight curve that is too steep or shallow is unfavourable. Those of the highest skill level can also consistently compensate for a lack of inrun speed with perfect timing off the table and an excellent transition.
