The aircraft had been dispatched under minimum equipment list requirements with a brake defect that required the gear retraction to be delayed by one minute. When the flaps were extended to position 3 while flying at 210 KIAS, the maximum speed reduced to 195 KIAS causing an overspeed warning for about 10 seconds. Following autopilot disconnection and pitch increase the aircraft climbed to 3500 feet stabilizing at 170 KIAS, when the flaps were retracted to position 0, now increasing the stall speed Vs to 200 KIAS and VLS (lowest selectable speed) to 185 KIAS. Alpha Floor Protection did not activate as the triggering criteria were not yet met. The flaps were returned to position 1, the pitch was lowered to accelerate reaching 3900 fpm sink rate and a bank angle of 45 degrees while turning towards TINLY. Once level at 2500 feet and achieving 220 KIAS the flaps were retracted, the autopilot was re-engaged and the flight continued to destination without further incident.
