100% VERIFIED ANSWERS|ALREADY GRADED A+ |
UPDATED TO PASS
Semi Wing Span Correct answer-38.6
Semi turning radius Correct answer-33.0
What is wing loading? Correct answer-A useful measure of the general manuvering performance of
an aircraft.
Measure of loaded weight/wing area.
The higher the number, the lower the maneuverability, high takeoff/landing speeds.
20.7 psf in semi
What is power loading? Correct answer-10.6 pph
Ratio of the weight of the semi (3800) to the horsepower (total 360). Power to weight ratio
Max weights of semi (ramp, t/o, landing, baggage) Correct answer-Ramp: 3816
T/o: 3800
landing: 3800
Baggage: 200
What is zero fuel weight? Correct answer-Aircraft weight without any fuel onboard. It's purpose is
to ensure increased weight in the fuselage does not put too much stress on the wings.
What kind of structure does the semi have? Correct answer-Semi-monocoque frame, meaning it's
composed of stringers and bulkheads
What kind of wings does the semi have? Correct answer-Semi-tapered
Maximum speed on storm window Correct answer-129 KIAS
How are the flight controls linked/actuated? Correct answer-Direct linkages; chains, rollers, and
cables
What kind of ailerons do we have? Correct answer-Modified frise with differential travel
What is an antiservo tab? Correct answer-Meant to make movement more difficult, improve
stability, and provide more feedback. They travel in the same direction as the control surface
What is the advantage of the t-tail? Correct answer-Places the horizontal stab in undisturbed
airflow
Why is the deep stall dangerous? Correct answer-Can make recovery unrecoverable because of
loss of elevator authority
How does the semi counter risk of deep stall? Correct answer-Stabilator down spring
What kind of design do the flaps have? How do they stay in place? Correct answer-Single slotted;
Over center lock
, What kind of engines does the fuel injected have? Correct answer-L:IO-260-B1G6
R:LIO-360-B1G6
What kind of engine do the carb semis have? Correct answer-L: IO-360-A1H6
R: LIO-360-A1H6
What is the cylinder firing order? What are they set they way they are? Correct answer-L: 1,3,2,4
R: 1,4,2,3
Firing order is to provide balance and eliminate vibration
Where is the manifold pressure probe? Correct answer-Inboard rear cylinders
Where is the primer probe? Correct answer-Other three cylinders
Why is temperature control important in engines? Correct answer-Heat weakens and shortens the
life of the engine's internal parts. Heat also impairs lubrication; Oil that is too hot gets too thin,
leading to lower pumping pressure and therefore a reduced ability to properly lubricate
What are the methods the semi has to cool the engine? Correct answer-Air, Oil, Fuel
What are the notable CHT temperatures and limits? Correct answer-Best economy 400F
Best power 435F
Maximum 500F
What is shock cooling? Correct answer-Metals shrink at different rates when cooled; Internal parts
of different composition that are mated together can form leaks at the seals, which increases
potential for compression loss
How does the carbuerator work? What does the throttle do Correct answer-The pressure in the
venturi is reduced due to reduced diameter (Bernoulli's principle). This causes the fuel and air to be
drawn in and mixed before it goes off to the combustion chambers to be burned. The throttle
controls the fuel/air flow by adjusting the throttle valve
What are pro and cons of fuel injected? Correct answer-Pros: Reduction in icing, better fuel flow,
faster throttle response, precise mixture control, better fuel distribution, easier cold weather starts
Cons: Difficulty starting a hot engine, vapor lock during ground ops on hot days, problems restarting
an engine that died due to fuel starvation
What are the pros and cons of carbureted? Correct answer-Pros: Cheap, large fuel lines (harder to
clog), relatively simple
Cons: Prone to carb icing, fuel can be discharged at low pressure leading to incomplete vaporization,
abrupt maneuvers can disrupt float, fuel distribution not as accurate
What are the conditions needed for carb icing? Correct answer-Carb ice most likely when temp is
below 70 F and humidity is above 80%. Temp drop into carb can be up to 60-70 degrees, therefore a
60 degree drop with a 70 F outside temp puts the temp inside the carb at 30 F (below freezing)
What is the best indication of carb icing? Correct answer-Increase in fuel flow or loss of RPM. As
ice forms in the venturi, RPMs would decrease so the carb would increase fuel flow to maintain
