text: There may be many other specific differences 
  in the technique necessary to effect spin re- 
  covery . The effectiveness of the rudder during 
  recovery may be altered by the position of 
  elevators or horizontal 
  tail. Generally, full 
  aft stick may be necessary during the initial 
  phase of recovery to increase the effectiveness 
  of the rudder. The use of power during the 
  spin recovery of a propeller powered airplane 
  may or may not aid recovery depending on the 
  specific airplane and the particular nature of 
  the slipstream effects. The use of power during 
  the spin recovery of a jet powered airplane 
  induces no significant or helpful flow but does 
  offer the possibility of a severe compressor 
  stall and adverse gyroscopic moments. Since 
  the airplane is at high angle of attack and 
  sideslip, the flow at the inlet may be very 
  poor and the staI1 limits considerably reduced. 
  These items serve to point out possible dif- 
  ferences in technique required for various con- 
  figurations. The spin recovery specific for 
  large, long 
  fuselage can exhibit a significant moment con- 
  from the fuselage alone. The cross
