3.  2-1-2(a)(3): 3.5 degrees.

4.  2-1-2(b): Slightly high.

11.  2-1-2(e):  ___       ___
	       [___] ___ [___]

12.  2-1-3: Runway End Identifier Lights.  They are used to provide rapid and positive 
	identification of the approach end of a particular runway.

13.  2-1-4(b): You are landing on an instrument runway and you have 2,000 feet or half the 
	runway (whichever is less) remaining.

14.  2-1-4(c): Red

15.  2-1-5(d): There should be a row of pulsating white lights installed across the hold 
	short point.

16.  2-1-1&2: AS many as you want, you cannot control adjust the VASI brightness.  That is 
	dones through a photocell.

17.  2-1-7(b): 15 minutes.

18.  The only lights that may be extinguished are the 1 & 2 step REILs by clicking 3 or 5 
	times.  Otherwise the lights will extinguish themselves 15 minutes after the last 
	activation.

19.  2-1-7(c): 7 times within 5 seconds.

20.  2-1-7(c): Overflying the airport, or just prior to entering final segment of an 
	approach.

21.  2-1-7(d): A/FD

22.  2-1-8(a)(2): Faster, 30 to 45 flashes per minute.

23.  2-1-8(b)(4): It is the coded identifier for a lighted water airport.  You will also 
	see a white & yellow beacon nearby.

24.  2-1-8(b)(5): Lighted heliport.

25.  2-1-8(d): NO!!!!!!  Because at some locations ATC personnel turn the beacon on or off 
	when controls are in the tower.  Also, some are turned on by photoelectirc cell or 
	clocks and ATC cannot control them.  Thus, the operation of an aiport beacon 
	during the day is a good indication of IFR, however it does not necessarily mean 
	IFR conditions exist.  Do NOT rely on it for such an indication, use ATIS of AWOS.

26.  2-1-9(b): Green

27.  2-1-9(d): They are runway guard lights.  They are used to help you identify 
	taxiway/runway intersections in low visibility.

28.  2-2-2(b): A light that can be clearly seen from only one direction.  They are found 
	in conjunction with the rotating beacons of the federal airway system.  They 
	direct coded beams of light.

29.  2-2-3(a)(3)&(4): It either has high intensity white obstruction lights, or dual 
	lighting.

30.  2-2-3(c): On the top of the structure and lower part of the span.  They flash middle, 
	top, then lower.

31.  2-3-1(c): Make the operator of the airport aware of the problem, or use as ASRS form, 
	or report it to the FAA regional airports division.

32.  2-3-3(d): 1,000 feet.  Two rectangular broad white stripes.

33.  2-3-3(h): Relocated - Closes not only a set portion of the approach end of a runway, 
				but also shortens the length of the opposite direction 
				runway.
	       Displaced - Does not close any portion of the runway, just shortens 
				landings distance on the approach end.

34.  TBL 2-3-2: 100 feet

35.  2-3-3(i): No, you are still on a taxiway until you cross the demarcation bar.

36.  2-3-4(g): A geographic position mark used during low visibility taxiing to identify 
	where you are.  They are numbered consecutively for your route.

37.  2-3-4(e): To the direction in which they indicate a turn.  For example, for a left 
	turn the markings will be on the left side of centerline.

38.  2-3-5(a)(1): When all parts of the aircraft have crossed the applicable holding 
	position marking.

39.  2-3-5(c): You will see a single dashed yellow line across the taxiway before the

40.  2-3-6(b): VOR receiver checkpoint

42.  2-3-6(d)&(e): Permanently closed - Lights shut off, threshold, runway designation and 
					touchdown markings obliterated, yellow crosses at 
					each end of runway and at 1,000 foot intervals.
		   Temporarily closed - Yellow crosses only at each end of the runway.

43.  2-3-7: Mandatory instruction signs, location signs, direction signs, destination 
	signs, information signs, and runway distance remaining signs.

44.  2-3-8(b)(1): Black sign with a yellow letter "A" and yellow outline, next to a red 
	sign with white "31R"

45.  2-3-8(b)(3): This is a ILS critical area hold, when ILS is in use you will be 
	instructed to hold short of this.

46.  2-3-9: Runway boundary sign (a graphic depiction of the hold lines with the lines in 
	black and a yellow background), next to a black sign with a yellow letter "C"

47.  2-3-10(c): Before and on the left

48.  2-3-11(a): It is a destination sign telling you how to get to runway 4.

49.  2-3-13: 1,000ft or not less than 950 feet.

50.  2-3-14(b): arresting cables cross over the runway.
