Definitons
This force opposes the forward motion of an aircraft
What is drag?
This type of drag is caused by parts of the aircraft that do not produce lift
What is parasite drag?
This type of drag is created by parts of the aircraft that generate lift.
What is induced drag?
Aircraft designers use this feature to reduce form drag at the wing tips
What are winglets?
These are the two main types of drag that act on an aircraft.
What are parasite and induced drag?
This component of parasite drag is caused by the shape of an object moving through air.
What is form drag?
Induced drag increases as this angle increases.
What is the angle of attack?
Removing dirt, dust, mud, or ice helps reduce this type of parasite drag.
What is skin friction?
Drag is one of the four forces of flight along with...?
What is weight?
This type of parasite drag occurs because air clings to the surface of the aircraft.
What is skin friction?
This visible airflow effect at the wing tips shows the presence of induced drag.
What are wing tip vortices?
Removing this design feature reduces parasite drag
What is parasite drag?
This force helps make controlled flight possible by allowing pilots to maneuver the aircraft.
What is drag?
Landing gear, antennas, and fuselage mainly increase this type of drag.
What is parasite drag?
Because induced drag is linked to lift, it can never be completely ________.
What is eliminated?
The best time to minimize induced drag is during this stage.
What is aircraft design?
