#1= If you can only see a green light, where is the aircraft in relation to your aircrafts nose?
#2- If you can only see a white light, where is the aircraft in relation to your nose?
#3- If you can only see a red light, where is the aircraft in relation to your nose?
#4-If you can see both a red and a green light in front of your aircraft, and the red is on the right and the green on the left, which direction is the aircraft you are viewing traveling?
#5- If you can see only 4 "pale" blue lights in a neat row, what are you looking at?
#6- How can you tell if an airport is under IFR flight rules, by observing the airport beacon?
#7- What are REIL lights?
#8- What color are airport taxi lights?
#9- How long is the "Rabbit" lights at an airport?
#10- On your instrument panel, you have a row of 3 lights, spaced closely together, usually at the eyebrow of the instrument panel, "purple, amber and white", what are they and how are they used?

:airplane: The standard "safety" navigational lights as approved by all the nations of the world are RED, WHITE and GREEN!
#1= If you can only see a green light, where is the aircraft in relation to your aircrafts nose?
It is headed this way >>--->
#2- If you can only see a white light, where is the aircraft in relation to your nose?
It is headed away from me
#3- If you can only see a red light, where is the aircraft in relation to your nose?
It is headed this way <--<<<
#4-If you can see both a red and a green light in front of your aircraft, and the red is on the right and the green on the left, which direction is the aircraft you are viewing traveling?
It is headed towards me, and we may be in danger of getting a "you have collided message"
#5- If you can see only 4 "pale" blue lights in a neat row, what are you looking at?
Obviously a UFO

#6- How can you tell if an airport is under IFR flight rules, by observing the airport beacon?
When you are unable to see it at all you should be flying IFR
#7- What are REIL lights?
"Runway starts here" Used to prevent the pilot from having a REIL bad time.
#8- What color are airport taxi lights?
Blue to mark the "dont go past here" and green to mark the "follow this line down the center"
#9- How long is the "Rabbit" lights at an airport?
35 meters, which is exactly how far a rabbit can travel on tarmac in 15 seconds
#10- On your instrument panel, you have a row of 3 lights, spaced closely together, usually at the eyebrow of the instrument panel, "purple, amber and white", what are they and how are they used?
I assume in order. Don't panic, Panic, and freak out
How did I do sir? I'll be honest I had to try some educated guesses there.

10: ILS outer, middle, inner markers??? (And in case I get that horribly wrong, don't worry- there is no danger I will ever fly a real plane. It comes from a few brain cells left over from MS Flight Sim.)

:airplane: Red light is on left wing tip, Green is on right wing tip and white light is on rudder or somewhere on tail assy.
#1- If you can only see green light, a/c is moving from your left to your right.
#2- If you can only see a white light, you are following an a/c in front of you...you might be catching him. Sometimes in accidents in past, tail light was mistaken for a star, now all the navigational lights are strobe lights but still colored the same.
#3- If you can only see a red light, the a/c is moving from your right to your left.
#4- The a/c is coming directly at you!
#5- Formation lights on a B-29! ( sorry, was trick question)
#6- Airport beacon, under Visual Flight rules, displays a rotating white and green light. If instrument flight rules are in effect, visibility less than 3 miles and ceiling less than 1,000 feet, beacon will become 2 split white lights.
#7- Runway end identification lights
#8- Blue
#9- 600 feet
#10- These three lights mark your outer marker, middle marker and inner marker as you pass over them. Outer markers are purple light and are usually 4 to 7 miles from end of runway.
Middle marker is amber and is usually 5/10ths of a mile up to 8/10ths of a mile from end of runway. Middle marker is white and is usually at the threshold of the runway. You should always consult your instrument landing system instructions for each runway which you intend to use the ILS system, as some markers and lighting systems are different distance, based on the category of type of approach approved for that runway. Jeppenson chart systems have great ground school reference material on their web site.

My tongue in cheek answer to #8 referred to an accident that happened 12-19-83 at Anchorage International. At about midnight a Japan Airline 747 landed on one of our Field Maintenance pickups doing a runway friction check of the runway. Controller error, both had been cleared onto the runway. Trust me when I say a Ford F-150 can't carry a 747. Driver seriously injured but survived.
Onto the taxiway lights.....around 3AM the airfield was reopened and a China Air 747 was cleared to land on runway 6L. The accident had happened on 6R, it had been very foggy all night with RVR as low as 800. (RVR is Runway Visual Range given in feet. Number is obtained by an instrument that uses a light and light sensor.) Anyway several of us are out on 6R picking up debris from the pickup and 747, tower gives us a call and tells us China Air will be landing on 6L. We start hearing China making the approach and it sounds like he's coming right at us. Looking around I see everyone else is looking for somewhere to run as China does a go around right over 6R!! Oh boy. He makes another approach and lands on 6L. After getting some fuel he depart for his final destination. When the fog cleared the next morning we find that there were several hundred feet of runway lights that had been runover by the China Air flight. It was obvious he had lined up on the edge lights when he obtained visual contact with the runway, touched down on the edge lights then steered back to center when he realized what he had done. He departed without letting anyone know what he had done.

:mad: Sorry guys, #10, 3rd light, white is INNER marker, not middle marker as I stated! The inner marker is usually on the threshold of the runway. To much junk running through this old brain right now.

I thought the split white light was military fields?

It is. Single white flash is a civilian field.

:airplane: Here is a list of the various FAA approved rotating beacon systems in use today in the U.S. 1.White and Green — Lighted land airport
2.Green alone* — Lighted land airport
3.White and Yellow — Lighted water airport
4.Yellow alone* — Lighted water airport
5.Green, Yellow, and White — Lighted heliport
6.White, White, Green* — Military Airport
7.White, Green, Red — Hospital and/or Emergency Services Heliport
Military airport beacons flash alternately white and green, but are differentiated from civil beacons by two quick white flashes between the green flashes.
In Class B, Class C, Class D and Class E surface areas, operation of the airport beacon during the hours of daylight often indicates that the ground visibility is less than 3 miles and/or the ceiling is less than 1,000 feet. Regardless of the weather conditions, the FAA has no regulation that requires airports to turn the beacon on during the day.
At some locations with operating control towers, Air Traffic Control (ATC) personnel turn the beacon on or off with controls in the tower. At many airports the airport beacon is turned on by a photoelectric cell or time clocks, and ATC personnel cannot control them.
Following pic's are examples of airport rotating beacons in use today in the U.S.

:airplane: No, the above pic's are just examples of what the different rotating beacons look like. I have listed in a previous answer the 7 main rotating beacons being used in the U.S. today. I will admit, more people, miss these questions on the FAA exams. It depends on which exam you get when you take your written for the various FAA certificates. The FAA routinely changes the various exams to keep people from copying questions and passing them on to other applicants. You might just get one question on these beacons and you might 2 or 3, or sometimes, non at all. These types of questions are usually just on the private pilot written exam, but they could show up on others.
I am working on practice exams now, which if God doesn't have me report to the big hangar in the sky, should be ready before long, I intend to provide a link for anyone to practice on them, prior to taking the official exam. Of course I will grade them for anyone at no cost.
My main purpose in posting something like these questions are for people in Aces High who are working on a rating and preparing for the written exams.

One you should probably discuss is glide ratio. From present position it is 1/2 the distance to the nearest airport. :x

:airplane: You make a good point and one of the reasons that I have avoided glide spec's is this: as you know, a whole host of varables are involved in the true glide distance of any aircraft, density altitude, head wind, tail wind, damaged or not, different weights of aircraft and where are not the aircraft's engine can be "feathered". Most single engine aircraft does not have a feathering prop, as there is no real purpose to have one. I have, over the years, heard argument after argument as to the benefit of slowing up until the prop on a single engine aircraft quits "windmilling" or should you continue to let the prop windmill, to harvest some perceived notion that the windmilling prop provides some thrust. Some people advocate that while the engine is windmilling, the oil pump is still working enough to reduce the prop to full decrease RPM, but I have always had my doubts about the advantage in that!
While working as a flight instructor in 1963, I had a student pilot working on approach to landing stalls with full flaps down in a Cessna 150. We lost 18 inches of one of the blades and I quickly snatched the nose up, pulled mixture and engine stopped immediately. Proceeded to land in a cow pasture just west of Fairburn, Georgia. Our head mech. replace the prop and after the farmer moved his cattle to one end of pasture, took off and returned to Charlie Brown airport. Had we been doing anything other than what we were doing at the time of separation, I would not be here typing this! All the other 12 Cessna 150's and Cessna 172's in the school fleet were promptly "magnafluxed" for cracks and one other aircraft had a small crack, but was not large enough to be a danger.

Yeah, there is a lot of those things folks think is "the" thing to do in a situation that in reality offer little advantage and many times put you at more risk.
I think a stopped prop is much less drag than a windmilling prop but you probably lose any gain of stopping the prop in the act of getting it stopped. On low powered aircraft it might be reasonably easy to get the prop stopped by slowing up but on higher powered aircraft you may have to slow below stall speed to get the prop stopped. I've made 3 dead-stick landings and in all of them the prop continued to turn until I was on the ground.
As for pulling the prop RPM back I found that at least on my 182 it does reduce drag to reduce prop RPM. I tested by bringing the power to idle and stabilized in the glide. I would then pull the prop control out and the aircraft would gain 3-4mph in airspeed (I maintained the same pitch attitude). When the prop control was pushed back in the speed would drop off. Not a huge difference but if you're having to stretch to make a safe landing I'd certainly give it a try.
I'll bet that was interesting when the prop came apart. Shake a bit did it? :devil

:airplane: Actually, it was a quick viberation and cowling shake, because as soon as it happened, I pulled the nose up and pulled the mixture, and the aircraft did stall, but recovery was no problem and I had about 3,000 feet AGL to work with and the practice area that we used was over several cow pastures and corn fields. I was more concerned about the nosewheel wiping out on rough ground and nosing over, but as it turned out, the grass all over that pasture was pretty short because of all the cattle feeding on it. The part I was most nervous about was the student pilot I had in the 150 was the wife of the District 9, Southeast district,(9 states), FAA flight surgeon. I knew that this forced landing was going to looked at very closely, but as it turned out, she and I both were interviewed by a local TV station the next day, explaining what happened. She went on to solo in around 9 hours or something like that and obtained her Private Pilot certificate in about 50 hours. She was an excellent student and those were the kind of students I really enjoyed working with!!

"There... Are... Four... Lights!" was a reference to a Star Trek episode. But I like your explanation of the lights.
