Unformatted text preview: this isn't a very large velocity relative to V_TD, so using 0.7 V_TD as the average velocity seems pretty reasonable If the carrier is moving 24 mph, then the airspeed of the aircraft will go from VTD to Vw what distance is needed to decelerate from VTD to Vw how long it takes to decelerate: (VTD-Vw)/a_avg carrier will travel this distance during the ground roll. . .
