Analysis

During a takeoff attempt, the right seat pilot did not get an airspeed indication. However, the left airspeed indicated 45 mph when the pilot aborted the takeoff. The aircraft veered off the right side of the runway 1700 feet from the initial takeoff roll. Runway 06 is 4250 feet long. The planned liftoff speed should have been 80 mph at 5000 pounds gross weight with a total takeoff distance of 1200 feet. This takeoff data is based upon a level, dry, paved surface. FAA advisory circular 91-6A states that takeoff should not be attempted with greater than 1/2 inch of wet snow on the rwy surface. The plt reported that the rwy was covered with 4 inches snow
