Here's another one to have a go at. This time I won't be forthcoming with the answers for a while - to give everyone who wants to a chance to chime in.

Q1. According to the Centers for Disease Control, if an airline passenger is in the coughing stage of influenza, the virus will be spread to what percentage of the other passengers and crew aboard that flight?

Q2. A pilot approaches a small house while flying over an otherwise flat, featureless desert. It is legal for him to fly 400 feet abeam the house at an altitude of 400 feet agl?

Q3. The most direct and adverse effect of humidity on aircraft performance is:
a. Reduced lift.
b. Reduced propeller thrust.
c. Reduced horsepower.
d. Increased drag.

Q4. Why does it appear to the casual observer (standing to the side and at some distance) that a departing Boeing 747 climbs at a slower airspeed than a smaller jet departing at the same speed and climb angle?

Q5. A pilot flying a jet airplane at high altitude for long periods of time could be concerned about freezing:
a. Fuel.
b. Hydraulic fluid.
c. Oil.
d. None of the above.

Q6. What causes a reciprocating engine to backfire?

Q7. Why is the abbreviation for coordinated universal time UTC instead of CUT?

Q8. Why is the pilot's compartment of an airplane referred to as a cockpit?

Q9. A pilot drains a sample from a wing tank containing an approximately equal mixture of 80/87 octane (red dye) and 100/130 octane (blue dye) fuel. The sample will have the appearance of:
a. Water.
b. Jet A fuel.
c. 80/87 octane fuel.
d. 100/130 octane fuel.

Q10. True or False: The decision height for an ILS approach to Kennedy Airport is 13,510 feet.

A1: 20% (just a guess)

A2: Yes, because you're more than 500 feet from the person or property.

A3: C

A4: It looks relatively slower because it's traveling less plane lengths per second

A5: D

A6: Detonation, maybe from cheap fuel

A7: The European translation comes out as UTC?

A8: This one I looked up. Maybe this is wrong though: "The word "cockpit" in its oldest senses means a pit for cockfights. British warships of the 17th Century had an auxiliary steering compartment deep in the ship, near the rudder. Legend has it that during battle, wounded sailors were housed there. Sailors began to call the blook-spattered compart- ment the cockpit. Eventually , the steering area on the main deck was described as the cockpit. With the dawn of aviation, pilots adopted the term "cockpit" to describe the equivalent section of an airplane."

A9: A

A10: False

Without looking anything up....

Q1. Not even gonna try...

Q2. As long as they can't see your tail number!  Big grin
But really, if you're at least 500' from the thing you're legal.

Q3. The most direct and adverse effect of humidity on aircraft performance is:
c. Reduced horsepower.

Q4. Why does it appear to the casual observer (standing to the side and at some distance) that a departing Boeing 747 climbs at a slower airspeed than a smaller jet departing at the same speed and climb angle?

Probably because the 747 is much longer, and takes more time for the entire length of the plane to pass a stationary point from the viewer's perspective.


Q5. A pilot flying a jet airplane at high altitude for long periods of time could be concerned about freezing:
b. Hydraulic fluid.
maybe...

Q6. What causes a reciprocating engine to backfire?
Excessively rich mixture that is still burning on it's way out the exhaust pipe.

Q7. Not gonna try that one either...

Q8. See aswer to Q7

Q9. A pilot drains a sample from a wing tank containing an approximately equal mixture of 80/87 octane (red dye) and 100/130 octane (blue dye) fuel. The sample will have the appearance of:
clear

Q10. True or False: The decision height for an ILS approach to Kennedy Airport is 13,510 feet.

Uuhhh, false!

Q1. According to the Centers for Disease Control, if an airline passenger is in the coughing stage of influenza, the virus will be spread to what percentage of the other passengers and crew aboard that flight?

--> No idea, but I'll go with 25%

Q2. A pilot approaches a small house while flying over an otherwise flat, featureless desert. It is legal for him to fly 400 feet abeam the house at an altitude of 400 feet agl?

--> hum..... No, think 500ft is the number.

Q3. The most direct and adverse effect of humidity on aircraft performance is:
a. Reduced lift.
b. Reduced propeller thrust.
c. Reduced horsepower.
d. Increased drag.


--> well, I'll go with increased drag... Thinking air density!

Q4. Why does it appear to the casual observer (standing to the side and at some distance) that a departing Boeing 747 climbs at a slower airspeed than a smaller jet departing at the same speed and climb angle?

--> because of it's size! Plane lengths or stationary object, it all comes down to size!

Q5. A pilot flying a jet airplane at high altitude for long periods of time could be concerned about freezing:
a. Fuel.
b. Hydraulic fluid.
c. Oil.
d. None of the above.


--> Fuel. Ever heard of Fuel/oil heat exchangers anyone? Water in fuel might freeze at altitude.

Q6. What causes a reciprocating engine to backfire?

--> Lean fuel air mixture. Flame front is slower, continues through the exhaust manifold.

Q7. Why is the abbreviation for coordinated universal time UTC instead of CUT?

--> Because it's based on French abbreviation, not English. (had to look-up this one on the net...)

Q8. Why is the pilot's compartment of an airplane referred to as a cockpit?

--> I have no idea... GoBoeing's explanation makes sense, I guess...

Q9. A pilot drains a sample from a wing tank containing an approximately equal mixture of 80/87 octane (red dye) and 100/130 octane (blue dye) fuel. The sample will have the appearance of:
a. Water.
b. Jet A fuel.
c. 80/87 octane fuel.
d. 100/130 octane fuel.

-->Isn't 100/130 green? Blue is for 100LL. Anyways, not to good in painting, have no idea what red and green/blue will make. I'll go with JET A, colorless.

Q10. True or False: The decision height for an ILS approach to Kennedy Airport is 13,510 feet.


-->false.



Hope I pass  Smile



if your flight goes MX in YUL, I might be called to fix it!

It's been long enough, here are the answers...

Q1: According to the Centers for Disease Control, if an airline passenger is in the coughing stage of influenza, the virus will be spread to what percentage of the other passengers and crew aboard that flight?
A1: 72 percent! If you're concerned about this and haven't got your annual flu shot you can obtain a prescription for amantadine from your doctor. This can be taken orally before a flight and provides almost immediate protection.

Q2: A pilot approaches a small house while flying over an otherwise flat, featureless desert. It is legal for him to fly 400 feet abeam the house at an altitude of 400 feet agl?
A2: Yes - according to Federal Aviation Regulation 91.119(c), an aircraft flying over sparsely populated areas "may not be operated closer than 500 feet to any...structure." In this case, the aircraft is 565 feet (diagonally) from the house.

Q3: The most direct and adverse effect of humidity on aircraft performance is:
A1: (c) Water vapor displaces some of the dry air that would otherwise be available for combustion, enriching the mixture and retarding flame propagation within the cylinders.

Q4: Why does it appear to the casual observer (standing to the side and at some distance) that a departing Boeing 747 climbs at a slower airspeed than a smaller jet departing at the same speed and climb angle?
A4: Large airplanes appear to move more slowly because it takes longer for them to travel a distance equal to their own length, which is the subconscious reference that an observer uses to estimate speed.

Q5: A pilot flying a jet airplane at high altitude for long periods of time could be concerned about freezing:
A5: (a) Fuel. This is why most turbojet aircraft have fuel heaters and/or are required to use fuel additives such as Prist or its equivalent.

Q6: What causes a reciprocating engine to backfire?
A6: The fuel-air mixture in the induction system is ignited by gases that are still burning in a cylinder when its intake valve opens.

Q7: Why is the abbreviation for coordinated universal time UTC instead of CUT?
A7: An advisory committee of the International Telecommunications Union could not decide in 1970 whether to use the English word order, CUT, or the French word order, TUC, so a compromise, UTC, was adopted.

Q8: Why is the pilot's compartment of an airplane referred to as a cockpit?
A8: A cockpit originally was the pit in which fighting cocks battled; it came to mean any small place where many battles are waged, as in the adage "Belgium is the cockpit of Europe." By analogy, World War I pilots in Europe referred to their cramped quarters as cockpits, which came to mean any place on an airplane or boat used by the steerman.

Q9: A pilot drains a sample from a wing tank containing an approximately equal mixture of 80/87 octane (red dye) and 100/130 octane (blue dye) fuel. The sample will have the appearance of:
A9: (a) Water or Clear - the dyes can neutralize each other and give the appearance of a clear liquid.

And finally, my trick question for the day...

Q10. True or False: The decision height for an ILS approach to Kennedy Airport is 13,510 feet.
A10: True - Kennedy Airport serves La Paz, Bolivia, which has an elevation of 13,310 feet msl (not to be confused with John F. Kennedy International Airport in New York).
