NAVWEPS O&ROT-SO  APPLICATION OF AERODYNAMICS  TO SPECIFIC PROBLEMS OF FLYl.NG  (5) Operating Data.  The performance of  each specific airplane defines its application to  various uses and missions. The handbook  operating data must be available at all times  to properly plan and elnccate  the flight of an  aircraft. Constant reference  to the operating  data will  insure safe and effective operation  of the airplane.  Great time and effort are expended in the 1  preparation of the flight handbook to provide  the most exact information, data, and pro-  cedures. Diligent study and continuous UC  of the flight handbook will ensure that the  greatest effectiveness is achieved from the  airplane while  still  operating within  the  inherent capabilities of the design.  invitation for trouble of many sorts.  The  normal and emergency procedures applicable  to each specific airplane will  insure the  proper operation of the equipment.  (3) Operating Limitatiom.  The operation of  the airplane and powerplant must be conducted  within  the established limitations.  Failure  to do so will invite failure or malfunction of  the equipment and increase the operating cost  or possibly cause an accident.  (4) Flight Characteristics. While all aircraft  will have certain minimum requirements for  flying qualities, the actual peculiarities and  special features of specific airplanes will differ.  These particular flight characteristics must be  well known and understood by the pilot.  412
