Narrative:
Departing white plains, ny, on runway 16, westchester 9 departure. Reclred to maintain 2000 ft instead of SID 3000 ft. Conditions at time of departure were wet runway, low visibility and marginal runway length. Departure was at maximum power and 15 degree flaps. Due to the aircraft weight and maximum performance takeoff requirements for a contaminated runway, my departure compliance with the westchester 9 was slow. After factoring the airport elevation of 439 ft, a new clearance to maintain 2000 ft, and a climb rate of 2500 ft/second, I reached 2000 ft before I could effectively comply with requirement to turn right 170 degrees to a heading of 320 degrees at 800 ft MSL. Additionally, I had to fly faster than the 190 KTS to comply with the speed command to turn at a standard rate turn and noise abatement procedures. This departure is asking too much of crew and aircraft performance. Asking pilots and plane to perform a 170 degree turn just after takeoff and low to the ground is a maneuver that should only be performed in the simulator. Additionally, the takeoff instructions for the westchester 9 departure are misleading and deceptive. A speed reduction at a lower altitude should be highlighted instead of being buried on the opposite side of the page under the disguise of a benign note.

Title: AN ACR CREW FOULED UP THE WESTCHESTER SID.
Narrative: DEPARTING WHITE PLAINS, NY, ON RWY 16, WESTCHESTER 9 DEP. RECLRED TO MAINTAIN 2000 FT INSTEAD OF SID 3000 FT. CONDITIONS AT TIME OF DEP WERE WET RWY, LOW VISIBILITY AND MARGINAL RWY LENGTH. DEP WAS AT MAX PWR AND 15 DEG FLAPS. DUE TO THE ACFT WT AND MAX PERFORMANCE TKOF REQUIREMENTS FOR A CONTAMINATED RWY, MY DEP COMPLIANCE WITH THE WESTCHESTER 9 WAS SLOW. AFTER FACTORING THE ARPT ELEVATION OF 439 FT, A NEW CLRNC TO MAINTAIN 2000 FT, AND A CLB RATE OF 2500 FT/SEC, I REACHED 2000 FT BEFORE I COULD EFFECTIVELY COMPLY WITH REQUIREMENT TO TURN R 170 DEGS TO A HDG OF 320 DEGS AT 800 FT MSL. ADDITIONALLY, I HAD TO FLY FASTER THAN THE 190 KTS TO COMPLY WITH THE SPD COMMAND TO TURN AT A STANDARD RATE TURN AND NOISE ABATEMENT PROCS. THIS DEP IS ASKING TOO MUCH OF CREW AND ACFT PERFORMANCE. ASKING PLTS AND PLANE TO PERFORM A 170 DEG TURN JUST AFTER TKOF AND LOW TO THE GND IS A MANEUVER THAT SHOULD ONLY BE PERFORMED IN THE SIMULATOR. ADDITIONALLY, THE TKOF INSTRUCTIONS FOR THE WESTCHESTER 9 DEP ARE MISLEADING AND DECEPTIVE. A SPD REDUCTION AT A LOWER ALT SHOULD BE HIGHLIGHTED INSTEAD OF BEING BURIED ON THE OPPOSITE SIDE OF THE PAGE UNDER THE DISGUISE OF A BENIGN NOTE.
