come down until flying speed has been attained. The wheel should
be
eased forward after the plane leaves the ground , however, or
the nose will point up too steeply for good climbing and it may
drop again momentarily with some loss of altitude. It is advisable
not to climb steeply after taking off, until an airspeed reading of at
least 60 MPH has been reached, because the airplane will fly at a
lower speed with full power than without power, and the engine
might possibly fail with the airplane at less than its minimum flying
speed without power.
In making a cross wind take-off, it is necessary to turn the control
wheel some to overcome weathervaning (see page 12). As speed is
gained and the ailerons actually begin to work, the upwind wing
will rise. However, the pilot should continue to steer down the
runway. The control wheel should not be pulled back too soon; be
sure to have flying speed so that the plane leaves the ground
completely. Neutralize the control wheel after the airplane breaks
contact. The nose will normally swing and point upwind just about
right to offset drift. The main thing is not to have the nose wheel
lose traction before the airplane can fly, as it will then roll along on
the rear wheels and turn into the wind.
MANEUVERING IN FLIGHT
After taking off, the steepest angle of climb to clear an obstacle is
usually obtained at an airspeed reading of about 60 MPH. The best
rate of climb for getting to altitude is obtained at an airspeed
reading of about 70 MPH near sea level and the reading becomes
lower as the altitude is increased, being about 60 MPH at 10,000
feet.
In flight without rudder pedals, turns are made simply by turning
the control wheel until the proper bank is reached and at the same
time keeping the nose in the position desired by adjusting the fore
and aft position of the control wheel. The airspeed required in a
steady turn is higher than in straight flight because the lift is not
vertical and only the vertical component of the lift will support the
airplane against gravity.
