text: For the professional aviator, there are few 
  documents which are as important as the air- 
  plane flight handbook. The information and 
  data contained in the various sections of the 
  flight handbook provide the basis for safe and 
  effective operation of the airplane. 
  
  Various sections of the flight handbook are 
  
  devoted to the following subjects: 
  (1) Equipment and Systems. With

  effective but adequate cyclic control must be 
  available. 
  If cyclic control has been lost, re- 
  covery must be effected by reducing power and 
  collective pitch and entering autorotation.

  it is imperative that the pilot be familiar with 
  every item of the aircraft. Only through exact 
  knowledge of the equipment can the pilot 
  properly operate the airplane and contend 
  with malfunctions. 
  
  (2) Operating Procedures. Good procedures 
  are mandatory to effect safe operation of the 
  airplane and its equipment. The complexity 
  of modern equipment dictates the use of special 
  and exact procedures of operation and any 
  haphazard or non-standard procedure is an
