AVIT 323 FULL SOLUTION BUNDLED
ASSESSMENT QUESTIONS AND CORRECT
ANSWERS
●● What generally happens to engine performance as altitude increases?
Answer: As altitude increases, performance decreases
●● What generally happens to performance as weight decreases?
Answer: Increases
●● What are the 3 types of hydroplaning?
Answer: Dynamic, Viscous and Reverted Rubber
●● What causes the 3 types of hydroplaning?
Answer: Dynamic: High speeds and Standing water
Viscous: Wet, painted surfaces of runway
Reverted Rubber: locked brakes
●● List all the forces the tail-down force must equal in level flight
Answer: Thrust drag line (pendulum): Slung or high wing engines make
it even worse.
Fuselage destabilizing moment: Things fall narrow side down.
, FWD wing pitching moment:Caused by difference of lift on top of wing
and bottom of wing
Lift weight coupling: affects by CG, fwd CG bad performance
Thrust - flight path:Difference between thrust and flight path
●● What exactly is L/D max, and what affects it?
Answer: The best lift to drag ratio, the endurance of the aircraft.
●● What is the definition of Range? Definition of Endurance?
Answer: Range is the total distance traveled by an airplane on a tank of
fuel while Endurance is the total time an airplane stays in the air on a
tank of fuel
●● As speed increases, what drag goes up? What drag goes down?
Answer: Induced drag goes down, and Parasite drag goes up as speed
increases
●● We know the three variables for air density are temperature, pressure,
and humidity. Explain how each affects air density.
Answer: We know the three variables for air density are temperature,
pressure, and humidity.
- TEMP: H = L DENSITY. Hot air expands.
- PRES: L =L low pressure is generally cooler air,
- HUM: H = L Water in liquid form is much less dense than air itself.
