Answer 1

Are you getting us to do your homework for you?  Are you cheating on a test?  You need to do some reading first.

Answer 2

1.  Due West assuming it's true and not mag

2. 21000ft with one's altimeter set to 2992

4. Instrument Landing System

5. South South East

6. Rwy 04

7. Approximately 1.15 mph or 1.85Km/h

8.  aReaNavigation allows one to fly point to point rather than station to station, basically.

9.  Headwind

10.  Route traffic SAFELY out of congested airspace.

Answer 3

1. depends on the wind, I have had to fly  a magnetic heading of  around 270° to fly a 240° course.

especially in slow flight (in the traffic pattern)

Answer 4

1) West

---> 270deg = west

---> 360deg/000deg= north

---> 090deg= east

---> 180deg= south

2) Means 21,000feet pressure altitude

---> Pronounced "Flight Level 210"

---> It's a number given in hundreds of feet

---> 210 x 100 = 21,000ft

---> Pressure altitude= Indicated altitude when altimeter is set to 29.92inHg

---> Used when above 18,000ft above sea level (MSL)

---> All aircraft above 18,000ft use 29.92 setting so they don't have to recalibrate so often

---> To increase accuracy in vertical aircraft separation

3) 250kts generally and in certain airspaces it's...

---> 200kt within 4nm and 2,500ft vertical of Class C or D airport

---> 200kt under Class B

---> 200kt through VFR corridor through Class B

---> Do not have to follow limits if aircrafts min safe speed is above the speed limit

---> All speeds are indicated airspeeds (IAS) (read from the airspeed indicator)

4) Instrument Landing System= A precision approach that provides horizontal and vertical guidance for a properly equipped aircraft down to 200ft (usually) above touchdown for a category 1 ILS

---> Uses LOC (Localizer) for horizontal guidance

--------> LOC uses marker beacons for giving position on LOC course (Outer marker, Middle marker, Inner marker) (OM, MM, IM)

---> Uses GS (glide slope) for vertical guidance

5) South

6) Rwy 04

---> 220deg - 180deg = 040deg

---> ATC won't always do this at large airports because it can be troublesome and costly to re-route all the traffic to a different route to a different runway

7) Covering 1 nautical mile in 1 hour

---> 1kt = ~1.15mph

8) Area Navigation

---> Navigation systems which provide RNAV capability include VOR/DME, DME/DME, LORAN C, GPS, OMEGA and self contained Inertial Navigation Systems (INS) or Inertial Reference Systems (IRS).

---> RNAV was developed to provide more lateral freedom and thus more complete use of available airspace. This method of navigation does not require a track directly to or from any specific radio navigation aid, and has three principal applications:

   1-A route structure can be organized between any given departure and arrival point to reduce flight distance and traffic separation

   2-Aircraft can be flown into terminal areas on varied pre-programmed arrival and departure paths to expedite traffic flow

   3-Instrument approaches can be developed and certified at certain airports, without local instrument landing aids at that airport.

9) Headwind

--->meaning you fly against the wind, head-on, to lower ground speed and reduce takeoff and landing distances

--->usually headwind unless you have a significant runway slope to deal with

10) To route traffic in a orderly manner out of a congested airspace.

--->Standard Instrument Departure = SID

--->Departure Procedure = DP

--->Purposes:

1-Simplify clearance delivery procedures

2-Reduce frequency congestion

3-Ensure obstacle clearance

4-Control flow of traffic

Trying to get into an flight sim ATC group huh? I hope they don't ask you additional questions :)

I added additional but incomplete info for those who are curious and in training.

Answer 5

All of Comair's answers are correct.

I would be a bit more precise about what FL210 means. It is short for 'flight level 210'. It means to fly at an altitude such that pressure is what the pressure would be at 21,000 feet if it were an International Standard Atmosphere day.

It would take a page or two to explain why it's quite this way, but the short version is this: When you're close to the ground, it's very important that your altitude correspond to the actual height over terrain. If you're flying at 10,000 feet, you should be able to get over a 9,500 foot obstacle. Since the altitudes are measured by an altimeter, which is a pressure gauge, they corrected for variations in pressure due to highs and lows. So at low altitudes, we adjust our altimeters based on readings of ambient pressure, usually taken at airports and weather stations. This keeps our actual terrain clearances constant even if the pressure changes due to storms, high pressure systems, and so on.

However, if you're flying at 21,000 feet, you're not concerned about obstacle clearance. Having to keep adjusting for variations in pressure (when there are no good ways to measure it up there anyway) would cause accidents as planes constantly had to juggle around to keep their altitudes correct due to changing pressures (or two planes crash into each other because they flew at the same actual altitude even with different assignments because they adjusted their altimeters based on different pressure readings).

So above 18,000 feet, we use flight levels, which means to fly so that the pressure stays constant, even if that means moving up and down a bit in actual height over terrain.

An amusing issue is that if the pressure is just right, FL180 can actually be *below* 17,000 feet. Under unusual pressure conditions, some flight levels become unusable.

To route traffic in a orderly manner into congested airspace (i think)

Area Navigation (RNAV) is a method of air navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigating directly to and from the beacons.
