ASTB-E 2025/2026 EXAM QUESTIONS
AND ANSWERS | 100% PASS
Absolute Altitude - 🧠ANSWER ✔✔The actual distance an object is above
the ground.
Absolute Pressure - 🧠ANSWER ✔✔Pressure measured from the reference
of zero pressure, or a vacuum.
Acceleration - 🧠ANSWER ✔✔Force involved in overcoming inertia; may be
defined as a change in velocity per unit of time
Accelerometer - 🧠ANSWER ✔✔A part of an inertial navigation system (INS)
that accurately measures the force of acceleration in one direction.
Adjustable-pitch propeller - 🧠ANSWER ✔✔A propeller with blades whose
pitch can be adjusted on the ground with the engine not running, but which
cannot be adjusted in flight. Also referred to as a ground adjustable
,propeller. Sometimes also used to refer to constant-speed propellers that
are adjustable in flight.
Advancing blade - 🧠ANSWER ✔✔A rotor blade that experiences an
increase in relative wind because of airspeed.
Adverse Yaw - 🧠ANSWER ✔✔A condition of flight in which the nose of the
airplane tends to yaw toward the outside of the turn. This is caused by the
higher induced drag on the outside wing, which is also producing more lift.
Induced drag is a byproduct of the lift associated with the outside wing.
Ailerons - 🧠ANSWER ✔✔Primary flight control surfaces mounted on the
trailing edge of an airplane wing, near the tip. Ailerons control roll about the
longitudinal axis.
air density - 🧠ANSWER ✔✔The density of the air in terms of mass per unit
volume. Dense air has more molecules per unit volume than less dense air.
The density of air decreases with altitude above the surface of the earth
and with increasing temperature.
Airfoil - 🧠ANSWER ✔✔Any surface, such as a wing, which provides
aerodynamic force when it interacts with a moving stream of air.
, Airspeed - 🧠ANSWER ✔✔Rate of the aircraft's progress through the air.
Airspeed Indicator - 🧠ANSWER ✔✔A differential pressure gauge that
measures the dynamic pressure of the air through which the aircraft is
flying. Displays the craft's airspeed, typically in knots, to the pilot.
Altimeter - 🧠ANSWER ✔✔An instrument that indicates flight altitude by
sensing pressure changes and displaying altitude in feet or meters
Ambient Pressure - 🧠ANSWER ✔✔The air pressure in the area
immediately surrounding the aircraft
Ambient Temperature - 🧠ANSWER ✔✔The temperature of the air
immediately surrounding the aircraft.
Angle of Attack - 🧠ANSWER ✔✔The angle formed between the wing chord
line and the relative wind.
Angle of Incidence - 🧠ANSWER ✔✔For an airplane, the angle formed by
the chord line of the wing and a line parallel to the longitudinal axis of the
airplane. For a helicopter, it is between the blade chord line and the plan of
rotation of the rotor system. In the absence of induced flow and/or aircraft
airspeed, angle of attack and incidence are the same.
