ATPL Exam Questions and Answers with
Verified Solutions | Latest Updated 2026
What are the forces acting on Drag. Thrust. Lift and Weight
an aircraft in flight?
What is direct lift control? The elevator / stabilizer provide the
direct lift control.
What are high lift devices? Trailing edge flaps. Leading edge
flaps. Slots
Define the two major types or Profile and induced drag which
Drag. equals total drag
What are high drag devices? Trailing edge flaps, spoilers, landing
gear, revere thrust, braking
parachute.
How do you prevent span-vise Fences, vortex generators
airflow on a wing especially
swept wing?
What is the purpose vortex To reduce spanwise airflow and
generators and fences? thereby reduce its effects
What are winglets and how do Winglets are aerodynamically
they work? efficient surfaces located at the wing
tips. They are designed to reduce
induced drag. They dispense the
spanwise airflow from the upper and
, lower surfaces at different points.
How does a forward center of A center of gravity forward of the
gravity affect the stall speed? center of pressure will cause a
higher stall speed
What advantages does an High mach cruise speeds, stability in
aircraft gain from a swept turbulence.
swing?
Where does a swept wing stall A simple swept or tapered wing will
first? stall at the wing tip first.
Explain speed stability. It's the behavior of the speed after a
disturbance at a fixed power setting
What is Mach Number Mach number is a true airspeed
indication, given as a percentage
relative to the local speed of sound.
What is the critical Mach Mcrit is the aircraft's mach speed at
number (mcrit)? which the airflow over a wing
becomes sonic.
What is Mach tuck? Is the nose down pitching moment
an aircraft experiences as it passes
it's critical mach number
What is the purpose of a mach A Mach trimmer is to automatically
trimmer? compensate for Mach tuck above
Mcrit.
