enough to nose it into the ground and thereby put excessive loads 
on the nose gear.  

Either of these conditions can be checked (by immediately opening 
the throttle) and at the same time exercising care not to lower the 
nose by pushing forward on the control wheel.  On the other hand, 

there is no point in steaming in at excessively high speed, even 
though the speed doesn't complicate things as it might were the air 
plane not landing level as it does on tricycle gear.  It is therefore 
recommended that the normal approach speed be held to the 

suggested range of 60 to 70 MPH. 

If, in the approach to landing, the pilot finds that he is overshooting 
slightly, he can nose the airplane down, remembering to level off 

and check the vertical velocity and put it on the ground 
immediately at a relatively high speed.  With immediate application 
of the brakes, the landing will require decidedly less overall 

distance than it would if

 

the airplane were held off the ground until 

minimum speed had been reached.  Also, if the approach has been 
made at too high an altitude the flight path can be steepened by 
rolling the airplane from side to side, dipping each wing 20 or 30 

degrees.   If the altitude is sufficiently high this can be done 
satisfactorily with the wheel full back, and height is lost quite 
rapidly, but, because of the high vertical velocity attained, the 

airspeed reading should be increased to 60 MPH or above at an 
altitude of about 200 feet, and the flight direction should be held 
straight from about 50 feet altitude to the ground 

In making cross wind landings, the airplane is headed or crabbed 
into the wind (See page 13). As the ground is approached the flight 
path is leveled o f f ,  and the airplane is held off the runway in the 
conventional manner until it loses flying speed. 

Contact is made with the ground while the airplane is still crabbed 
and the nose automatically swings so as to line the plane up and 
permit it to continue moving in the direction in which it was 

moving in the approach.  Therefore, at the time of contact the 
control wheel should be held lightly or momentarily released to 
permit this automatic adjustment.  During the ground run, hold a
