Air Department Sailors aboard USS Carl Vinson (CVN 70) are working toward carrier flight deck certification during the December underway period. The flight deck certification is a two-day process to conduct flight deck drills demonstrating Air Department can safely handle all emergency situations such as an aircraft fire or crashes on the landing area. The first day consists of day launching, day recovery and taxi drills during the night. Day two of the flight deck certification is day and night launch and recovery of the squadron aircrafts.
