-
Describe class A airspace. What must you do to enter it?
18,000 MSL and up. ATC keeps track of everyone. You must be IFR rated with an IFR plane.
-
Describe class B airspace. What must you do to enter it?
- Class B solid blue lines on the charts.
- You must establish 2 way communications with ATC to enter, and must also have a transponder with Mode-C, and you must receive ACTUAL CLEARANCE to enter. Listen for "cleared into the Class Bravo airspace".
- You must also have a transponder with Mode-C within 30 nm of the airport, or above it, even if you aren't within Class B airspace itself.
- Some class B airports have corridors - where you don't need a clearance to go through. You must read the Terminal Area Chart and follow the instructions.
-
Describe class C airspace. What must you do to enter it?
- ATC provides radar service in class C.
- Class C is a solid magenta line on the charts.
- You must establish 2 way communications with ATC to enter, and must also have a transponder with Mode-C.
- Class C looks like an upside down birthday cake.
- Class C is normally 4,000 feet AGL.
- ATC provides radar service, and some separation service.
-
Describe class D airspace. What must you do to enter it?
- Class D you must establish 2 way communications with ATC to enter it. If they also say something like "Cessna 574SP, stand by and remain clear of Class D airspace" you may not enter.
- Class D is shown with a blue dotted line, airspace extending to the ground.
- Class D usually extends to 2,500 feet AGL. A box with a number shows the MSL ceiling of the airspace.
- If the tower quits for the evening, class D turns into class E airspace.
- Standard is 4.4 nm, or 5 statute miles around an airport.
- You need a comm radio for equipment.
-
Describe class E airspace. What must you do to enter it?
- Class E with a floor of 1,200 ft AGL is shown with the fuzzy side of the blue. Class E with a floor of 700 ft AGL is shown as the fuzzy side of magenta.
- Magenta dashed lines shows the class E extends all the way to the surface.
- Class E has no equipment and comm requirements, but does have increased weather minimumns.
-
Describe class F airspace:
In the US, there is no class F. Foreign countries may have it.
-
Describe class G airspace:
Uncontrolled airspace. All airspace is class G unless otherwise designated.
-
airspace marked color deligniations - 8-4
see chapter 8-4
-
2 way communications occurs when?
- ATC references you by name: eg "Cessna 574 SP".
- If they say "Aircraft calling", that is not 2 way communications.
-
A transponder with Mode-C means?
It is equipped with altitude reporting. This is so ATC can give you radar service.
-
List speeds for 10,000+ feet, or below 10,000 feet.
- above 10,000 = no speed limit
- below 10,000 = 250 kts (KIAS)
-
List speed limit under class B, or in VFR corridors, or around class C + D airspace.
200 KIAS
-
Class G below 1,200 feet, above 1,200 feet, and above 10,000 ft. List minimum distance to clouds and visibility:
- below 1,200 ft: Keep clear of clouds and have 1 sm visibility.
- above 1,200 ft: 500 ft below clouds, 1000 ft above clouds, 2000 ft horizontally from clouds, and have 1 sm visibility.
- Night: same as above 1,200 ft for all altitudes, 3 sm visibility, unless you are at an airport, then it's normal.
- above 10,000: 1,000 feet above and below, 1 mile horizontal from clounds, and 5 m visibility
-
Class E cloud clearances to 10,000 ft:
- 500 feet below, 1000 feet above, 2000 ft horizontal, and 3 sm visibility
- above 10,000: 1,000 feet above and below, 1 mile horizontal from clounds, and 5 m visibility
-
Class C and D cloud clearances:
500 feet below, 1000 feet above, 2000 ft horizontal, and 3 sm visibility
-
Class B clould clearances:
Simply remain clear of clouds because ATC provides separation. 3 sm visibility
-
Cloud ceiling for VFR below B, C, D or E surface area has to be how high?
1000 ft
-
Describe SVFR
Special VFR- When minimums aren't good enough for VFR. You must request this, and it must be granted. Readback required. Cancel the clearance when no long required. SVFR is only legal under B, C, D or E airspace.
