SCAN Homework #15 Answers

AIM Chapter 7:

1.  7-1-1(b): 3 times daily and are god for 15 hours.  Route specific weather.

2.  7-1-2(b): A/FD..where else :)

3.  7-1-3(a): Standard, Abbreviated, Outlook.

4.  7-1-3(b)(4): Current conditions, including METARs PIREPs etc.  Normally they will give 
	it to you anyway, but in this ase they don't have to unless you request it.

5.  7-1-3(d): Whenever your proposed time of departure is six or more hours from the time 
	of the briefing.

6.  7-1-4(a): En Route Flight Advisory Service.  it is designed to provide en route 
	aircraft with timely and meaningful weather advisories pertinent to the type of 
	flight intended, route of flight, and altitude.  It is also a central collection 
	and distribution point for pilot reported weather information.

7.  7-1-4(a): 6AM to 10PM, 122.00 MHz.  5,000 feet MSL to 17,500 feet MSL.

8.  7-1-4(b): Use the name of the ARTCC (Center) facility in your area.  For example, over 
	Sacramento you would normally call Rancho Radio to talk to the FSS. However if you 
	called flight watch in that area you would be talking to Oakland Flight watch.

9.  7-1-4(e): No, flight watch is not for opening and closing flight plans, or receiving a 
	full pre-flight briefing.

10.  7-1-5(e): - Severe or extreme turbulence or clear air turbulence not associated with 
		thunderstorms.
	       - Severe icing not associated with thunderstorms
	       - Duststorms, sandstorms, or volcanic ash lowering surface or inflight 
		visibilities to below three miles.
     	       - Volcanic eruption

11.  7-1-5(c): Hourly at 55 minutes past the hour and are valid for two hours or until 
	superceeded by the next update.

12.  7-1-6(a): - MVFR: Ceiling 1,000 to 3,000 feet and/or 3 to 5 miles inculsive.
	       - VFR: Ceiling greater than 3,000 feet and visibility greater than 5 miles; 
			includes sky clear.

13.  7-1-7(b): No, it is not intended to substitute for a specialist provided briefing.  
	It is recommended for use as a preliminary briefing, and can help you make a go or 
	no go decision.

14.  7-1-11(d): ASOS
     7-1-11(b)(4): A discrete VHF radio frequency, or via telephone.

15.  7-1-15(a): METARS and TAFs are AGL, FA's are MSL unless prefixed with "CIG" then it 
	is AGL.  The "CIG" stands for ceiling, whenever you hear ceiling, think AGL.

16.  7-1-17(a)(1): Individual drops are not clearly identifiable; spray is observable just 
	above pavements and other hard surfaces.

17.  TBL 7-1-5: Moderate Chop.  Anytime you hear rhythmic, think Chop.  If there are 
	definite strains against the seat belt, it is moderate.

18.  7-1-24(c): 5 minutes

19.  7-1-24(d)(3): They may be embedded in heavy rain associated with a thunderstorm, or 
	in light rain appearing as virga.  If there is no precipitation present, a ring of 
	blowing dust/dirt is a go indication.

20.  7-1-26(b): Up to 20 miles.

21.  7-1-27(b)(6): Turn the lights to the highest intensity to lessen temporary blindness 
	from lightning.

22.  TBL 7-2-3: 360 feet MSL.

23.  7-2-3(b): It will be lower (go down).  So you will have less terrain clearance.  Just 
	remember "low to high, clear the sky" and "high to low, lookout below." It works 
	for both temp and pressure.

24.  7-3-3(b)(2): The shorter wingspan means that the vortex can be envelope the entire 
	aircraft.  With a larger wingspan, part of the wing will be outside the vortex and 
	will help to lessen the effect of the encounter.

25.  7-3-4(b): A light quartering tailwind.  The quartering (crosswind), will hold the 
	upwind vortex on the runway.  The Tailwind will move the vortex into the touchdown 
	zone.

26.  7-3-6(b)(8): 2 minutes

27.  7-3-7: Similar to vorticies of larger fixed wing aircraft.

28.  7-3-9(b)(1): 3 minutes, no this one you can waive. 

29.  7-4-2(d): Climb.  The lead birds are up top so once you get above them you are 
	clear.  But mainly, birds tuck their wings and dive to avoid you so if you get 
	above them you should miss them.

30.  7-4-3: FAA Form 5200-7

31.  7-5-3(b): 2,000 feet horizontal. The guy wires can extend out to 1,500 feet 
	horizontally.

32.  7-5-4(a): Many have, extended below them, either a suspension device to which the 
	payload or instrument is attached, or a trailing wire antenna, or both.

33.  7-5-5(c): When winds at your altitude exceed 35mph.  Downdrafts of 1,500 to 2,500fpm 
	are not uncommon.

34.  7-5-5(g): The same.  With the same IAS will give you a higher TAS and groundspeed, 
	but the same performance.

35.  7-5-5(h): The engine and propeller.  The engine gets less air, thus less HP.  The 
	propeller pushes less air per revolution. The wing is not affect as much because 
	with the sam IAS the wing should perform relatively the same.

36.  7-5-5(h)(1): Airports with elevations of 2,000 feet or higher.

37.  7-5-5(i)(1): Wind at 15kts or better blowing across the range at not less than 30 
	degrees.

38.  7-5-5(i)(3): Approximately 45 degrees.

39.  7-5-6: It provides pilots at unimproved airports with a reference point to judge 
	acceleration.  The aircraft should be at least 70 percent of takeoff speed by 
	that point, otherwise the takeoff should be aborted.

40.  7-5-8(c): Reduce thrust to idle and reverse course.

41.  7-6-1(d): Ten (10) days to ensure waiver of disciplinary actions.

42.  7-6-4: The National Institute for Discovery Sciences (NIDS).
