When you're ready to begin your descent from cruising altitude, move the prop pitch back to 15 and lower the King Air's nose slightly (reducing your prop pitch decreases the torque and drops the nose so this may not be necessary). If you need to adjust the balance after a few minutes to reduce pressure on control surfaces, trim down a bit. Your airspeed should be about 200 knots until you begin the approach.
When you leave the holding pattern to begin your approach, use your stick and yoke to level out the nose and adjust your trim until the indicator centers. Now lower your flaps a notch and drop the nose when your airspeed indicator reaches the white area (according to the June 2002 issue of AOPA Pilot, your approach flaps can come out at speeds up to 202 knots and you can fully lower the flaps at 158 knots). When your King Air settles, adjust the trim to match the attitude you need to maintain. If you're in level flight, your airspeed should be between 140 and 160 knots.
Since 184 knots is the maximum safe speed for lowering your landing gear (see the June 2002 issue of AOPA Pilot) and your current airspeed is 160 knots or less, it's time for the gear to come down. When you pass the final approach fix and are three miles out, drop your flaps to the second notch (your altitude should be about 1,000 feet). Arm the autofeather for your props and apply about 30 percent torque to both engines to maintain your airspeed at about 110 knots. Adjust your pitch and throttle settings to control your descent, and when you cross the threshold (first section of available runway) pull back the condition levers to flight idle (your airspeed should be about 90 knots).
It takes practice to master the flare (the stall just before touchdown) since you need to learn just how much to raise your nose and bleed off airspeed for a soft landing. Make sure you put the wheels down at the spot you've chosen then pull the condition levers back to ground idle, apply the brakes and set your props to reverse pitch to slow down before taxi.
