2025/2026
wing tip - Outboard most part of the wing
Red - Left wing light color
Green - Right wing light color
Spoilers - devices located on the wings that disrupt the airflow over the wing causing
loss of lift
Slats - Protrusions from the leading edge of a wing that, when combined with the flaps,
result in a significant increase in lift.
Primary Flight Controls - Ailerons, Rudder, Elevator
Secondary Flight Controls - Flaps, leading edge devices, spoilers and trim devices
Horizontal Stabilizer - An airfoil (usually at the back of an airplane) that resists up and
down changes in motion.
Vertical Stabilizer - A structure that creates left to right forces to keep the fuselage
aligned in yaw with the relative wind. The structure itself is vertical while the forces it
creates are horizontal.
Rudder - A controlling surface on an aircraft's tail that regulates yaw.
elevator - A rear horizontal stabilizer that controls up and down or pitching motion of the
aircraft nose.
Empennage - The tail assembly of an aircraft, including the horizontal and vertical
stabilizers, elevators, and rudder.
What curve does the standard wing have? - Upper curve
Flight Envelope - Encompasses the limits of speed, altitude, and angle of attack
required by any aircraft to maintain a stable flight.
Stalling speed - The minimum speed at which an aircraft can maintain level flight
Gravity - A force that pulls everything towards the earth at 9.8 m/s^2
Lift - An upward force created by the wing of the aircraft
Bernoulli's Principle - The air traveling over the top of the wing is faster than the air
traveling under the wing, creating lower pressure above the wing, causing lift
