This section covers checklists for basic aircraft with a fixed pitch prop and fixed undercarriage, as well as for advanced aircraft with a constant speed prop (CSU) and retractable undercarriage. It looks at engine run-ups, pre takeoff vital actions, after takeoff checks and before landing checks. Then there are the FREDA and HASELLL checks as well as emergency procedures. Finally there is a list of ICAO (International Civil Aviation Organization) type designators for common aircraft. You use these when filing a flight plan.
