121

What does the term yaw mean

directional turning from the tail section

122

The IFF on a military aircraft

indicates whether an aircraft is an enemy or ally

123

The line on an airspeed indicator to warn that operating above the indicated level is danderous is colored

red

124

When taking off into a headwind, the result will be

shorter takeoff distance and increased climb angle

125

If the elevator tabs on a plane are lowered, the plane will tend to

nose up

126

If one end of a rwy is number 27, what will the other end be

09

127

Flaps are generally used

during takeoff and landing

128

Air moving over the wing

moves faster than the air moving under the wing

129

What is the standard wight for gasoline in the acft

6lbs/gal

130

When in the down position, wing flaps provide

Increased lift and increased drag.

131

Municipal airports often provide at least one extended or unusually long runway to facilitate the take off of

Heavily loaded aircraft in calm conditions.

132

The small hinged section on the elevator of most airplanes is known as the

Trim tab.

133

The rearward retarding force on the airplane known as drag is opposed by

Thrust

134

At night, airport taxiways are identified by omnidirectional edge lights that are ______ in color

Blue

135

A runway with the Approach Lighting System (ALS) would show an incoming pilot

A series of lightbars and/or strobe lights extending outward from the runway approach end.

136

The thrust of a turbojet is developed by compressing air in the inlet and compressor, mixing the air with fuel and burning it in the combustor, and

Expanding the gas stream through the turbine and nozzle.

137

A ramjet engine consists of

An inlet, a combustion zone, and a nozzle.

138

The four forces that act on an aircraft in flight are

Lift, gravity, thrust, and drag.

139

For a fixed-wing aircraft, lift is generated _______ to the direction of flight.

Perpendicular

140

The angle formed by the chord of an airfoil or wing and the direction of the relative wind is known as the

Angle of attack

141

Pitot tubes furnish data to an instrument that is used by aircraft pilots in about the same way that a(n) _____ is used by an automobile driver.

Speedometer

142

The part of an airplane that holds the cargo and/or passengers, as well as providing a base for the other aircraft parts, is known as the

Fuselage

143

On a conventional fixed-wing aircraft, the _____ maintain(s) pitch and the _____ maintain(s) yaw.

Horizontal stabilizers, vertical stabilizer

144

_____ are additional hinged rear sections mounted to the wing near the body that are deployed downward on takeoff and landing to increase the amount of force produced by the wing.

Flaps

145

Which one of the following does not affect density altitude?

Wind velocity

146

The degree of movement of an aircraft around its longitudinal axis is known as

Bank

147

The Venturi theory of lift says that faster airflow over the curved upper portion of a wing surface causes

Decreased pressure according to Bernoulli's equation.

148

The maneuver in which a rotary-wing aircraft is maintained in nearly motionless flight over a ground reference point at a constant altitude and heading is known as

Hovering

149

The ratio of the speed of an aircraft to the speed of sound in the air around it is the aircraft's

Mach number

150

In a level turn, the acceleration experienced by the aircraft and its pilot in the direction perpendicular to the wing is solely determined by the

Bank angle
