Manufacturer's Empty Weight (MEW) - Answer the total weight of the aircraft as it was built.
Includes systems and components required for the aircraft to operate. Does NOT include the
weight of the baggage, passengers, or either usable or unusable fuel or fluid.
Operating Empty Weight (OEW) - Answer the MEW plus the weight of the crew, fluids,
unusable fuel, and the equipment required for flight. Does NOT include baggage, passengers, or
usable fuel.
All-Up Weight (AUW) or Aircraft Gross Weight (AGW) - Answer the total aircraft weight at any
given moment during a flight. The AUW decreases as fuel and fluids are consumed during the
operation of the flight.
Maximum Landing Weight (MLW) - Answer an aircraft's weight limit for landing. Exceeding this
weight increases stress on the landing gear and may affect the distance required for a safe
landing
Maximum Zero Fuel Weight (MZFW) - Answer the permissible weight of an aircraft with its
contents and includes unusable fuel. The total MZFW excludes the weight of usable fuel on
board and any consumable fluids
Maximum Takeoff Weight (MTOW) - Answer an aircraft's weight limit for takeoff. Exceeding
this limit increases the power required for takeoff, lengthens the runway distance needed for a
successful lift off, and places excess stress on the aircraft structure
Maximum Ramp Weight (MRW) - Answer the weight limit for an aircraft to taxi or be towed on
the ground
Flight Envelope - Answer Encompasses the limits of speed, altitude, and angle of attack
required by any aircraft to maintain a stable flight. An incorrect combination of these may result
in a stall, during which the aircraft experiences a decrease in lift and a reduction in airspeed
Angle of Attack (AOA) - Answer the angle measured between the direction of airflow against
the wing and the chord (an imaginary reference line the extends from the leading edge to the
trailing edge of the wing
Ailerons - Answer Located on from the midpoint of the trailing edge of the wing to the wing's
tip. Help with roll control
,Flaps - Answer located on the trailing edge of the wing; increase wing's surface area and
deflect the air flow downward. Allow planes to lift at slower speeds.
Spoilers - Answer Located directly forward of the trailing edge flaps to assist the ailerons in roll
control and to act as speed brakes for descent and landing. Extend upward to help reduce
airspeed (ex: raised when landing to help assist brakes in slowing airplane down)
Drag - Answer air resistance experienced during flight
Parasite Drag - Answer any "parasite" on the structure of the aircraft: low air pressure in the
tires, skin friction (any rough spot on the skin of the aircraft structure) This, along with any rivet
heads that may project above the skin, causes resistance to the air current flowing across the
wing.
Profile Drag - Answer Produced mainly by the shape of the aircraft. A smaller slimmer aircraft
reduces profile drag.
Induced Drag - Answer When, at the back of the wing, air flowing rapidly across the top meets
air flowing more slowly underneath, creating a vortex. This type of drag depends on the
performance of the aircraft. When lift, airspeed, and AOA increase, induced drag automatically
increases too.
When an airplane increases its lift, which statement is true about the air pressure flowing above
and below its wings? - Answer Air pressure is lower above the wings and higher below the
wings, producing lift.
Bernoulli's Principle - Answer As the speed of a fluid increases, its pressure decreases. Air
flows faster over the top of the wing leading to lower pressure. Air flows slower on the bottom
of the wing, increasing pressure. Upward push creates lift!
Longitudinal Axis (Roll) - Answer runs lengthwise from the nose to the tail
Lateral Axis (Pitch) - Answer runs wingtip to wingtip
Vertical Axis (Yaw) - Answer Runs perpendicular to the wings at the center of the aircraft
Trim - Answer Aircraft's desired position.
, Roll - Answer along the aircraft's longitudinal axis; controlled by ailerons, located at trailing
edge of the wings.
Pitch - Answer the lateral angle of ascent or descent; controlled by elevators, located in the
rear portion of the horizontal tail assebly
Yaw - Answer Controlled by the rudder, located in the rear part of the tail assembly;
movement of the rudder causes the nose to move from side to side.
Pressure Altimeter - Answer in the cockpit based on atmospheric pressure. Calibrated
automatically for 29.92 of mercury (Hg). Pilot resets the pressure altitudeindicator after
departing an airfieldto ensure the correct pressure altitude of the aircraft is displayed for the
destinatin airfield
Aircraft perform more efficiently in what weather? - Answer Colder wether because the air is
denser than warm air. (Except if air drops too low and de-icing is necessary) [high air density
increases engine performance]
Fuselage - Answer the main body of an aircraft that holds the crew, passengers, and cargo.
Wings, tail, engines, and landing gear attach to the fuselage, so it must be extremely strong to
withstand stresses while minimizing weight. Also helps stabilize plane in flight
Truss Struture - Answer Consists of welded steel-tubing longerons separated by diagonal
members to endure the loads placed upon the aircraft
Monocoque Structure - Answer consists of a thin sheet-aluminum alloy curved to fit the shell
of the fuselage. This metal skin is designed to withstand the stress of loads and minimize the
total weight the total weight of the aircraft.

total weight the total weight of the aircraft.
Semi-Cantilever Wing - Answer requires both internal bracing and external support from struts
attached to the fuselage
Biplane - Answer an airplane with two pairs of wings
Thickness - Answer a percentage of the wing chord; typically ranges from 6.5 to 13.5 percent
