Narrative:
Wet snow and blowing snow closed 1R and 1L alternating closings for snow removal. Called ground. No delays. Boarded, deiced, and departed gate on time. 45 mins in line accumulating snow on wings, when #1 for takeoff taxied back for another deice. Taxied out, took off after 40 mins with snow on wings well under gross, added 10 KTS to V speeds, redline power at takeoff. Left wing heavy, after climb check, gave aircraft to first officer (his leg). In climb, he kept taking out the right aileron trim I had applied. All carriers had the same problem except one large airline. They deiced again right before takeoff. Several other aircraft deiced 3 times (company policy limits them to 20 min) we have gate holds for boston, lga, ord, etc when they become overloaded. Why can't the FAA develop a similar program when long taxi delays occur due to runway closings during snow and freezing precipitation. I would rather wait, deice, and have a less than 10 min wait than to worry that the airplane might not fly.

Title: CAPT REPORTS HE TOOK OFF AT IAD AFTER A LONG WAIT AND TWO DEICINGS, WITH SNOW ON WINGS WHICH DISSIPATED IN FLT.
Narrative: WET SNOW AND BLOWING SNOW CLOSED 1R AND 1L ALTERNATING CLOSINGS FOR SNOW REMOVAL. CALLED GND. NO DELAYS. BOARDED, DEICED, AND DEPARTED GATE ON TIME. 45 MINS IN LINE ACCUMULATING SNOW ON WINGS, WHEN #1 FOR TKOF TAXIED BACK FOR ANOTHER DEICE. TAXIED OUT, TOOK OFF AFTER 40 MINS WITH SNOW ON WINGS WELL UNDER GROSS, ADDED 10 KTS TO V SPDS, REDLINE PWR AT TKOF. L WING HVY, AFTER CLB CHK, GAVE ACFT TO F/O (HIS LEG). IN CLB, HE KEPT TAKING OUT THE R AILERON TRIM I HAD APPLIED. ALL CARRIERS HAD THE SAME PROB EXCEPT ONE LARGE AIRLINE. THEY DEICED AGAIN RIGHT BEFORE TKOF. SEVERAL OTHER ACFT DEICED 3 TIMES (COMPANY POLICY LIMITS THEM TO 20 MIN) WE HAVE GATE HOLDS FOR BOSTON, LGA, ORD, ETC WHEN THEY BECOME OVERLOADED. WHY CAN'T THE FAA DEVELOP A SIMILAR PROGRAM WHEN LONG TAXI DELAYS OCCUR DUE TO RWY CLOSINGS DURING SNOW AND FREEZING PRECIPITATION. I WOULD RATHER WAIT, DEICE, AND HAVE A LESS THAN 10 MIN WAIT THAN TO WORRY THAT THE AIRPLANE MIGHT NOT FLY.
