> In landing configuration the 1011 had what was called “Direct Lift Control” or DLC. That feature was actually pretty cool. Once the airplane was in landing configuration the spoilers would come up to a neutral position of 7 degrees. If you moved the yoke forward, asking for an increased rate of descent, the spoilers would come up to a maximum of 14 deg but the pitch would not change. If you pulled the yoke back the spoilers would move toward 0 deg or stowed, thereby increasing lift and slowing descent. The DLC worked really well and made for super stable approaches with rock solid pitch attitude and rewarded you with “greaser” landings more often than other big jets I have flown.

Why does altering sink rate without changing pitch make for a super stable approach and "greaser" landing? The explanation I can think of is that moving spoilers is faster than pitching, allowing faster reaction times to errors.
