The essential controls of an airplane include the joystick, flaps, rudder and engine power. Moving the joystick sideways affects the ailerons on the wings causing the plane to bank to the left or right. Moving the joystick forwards and backwards affects the elevators on the tailplane so that the nose of the airplane moves down or up respectively. The aerodynamics of an airplane are extremely complicated. Changing one control usually has more than one effect. For example the ailerons do not simply cause the plane to roll, but produce a sideways airflow which causes the plane to turn as well.You may learn and experience these effects in the simulation.
The attitude and motion of an airplane is shown by many instruments and navigational aids in the pilot's cockpit, as discussed below. The pilot needs to use these instruments to navigate his airplane on to the right line or vector for approach to the runway, to fly his airplane on the right heading or bearing along that vector and to approach the runway with the right speed, altitude and descent angle to land the airplane.Typically, the correct approach angle of descent should be about 3deg which implies an attitude of about 6, 000 feet at 20 miles out, 3, 000 feet at 10 miles out and 1, 000 feet at just over 3 miles from the runway. The rudder controls can contribute to the turning of the airplane.When on the ground, while taxi - ing the rudder controls also steer the direction of the airplane.
