How far down does Class D airspace extend?

A

To the ground.

33
Q

What happens to Class D airspace when the control tower is no longer in operation?

A

That the Class D airspace extends up to, but does not include, that elevation.

Q

What happens if the extensions to Class D airspace extend beyond 2 nautical miles from the core area?

A

It becomes Class E airspace, and is shown with dashed magenta lines.

A

If the control tower is operating, and you are below the ceiling of Class D airspace, you must establish communications before you cross the blue dashed line.

41

A

You must have a comm radio, and you must establish communications with ATC.

42
Q

What must you do if you are landing at the non-primary airport in Class D airspace?

A

You must establish communications with the primary airport, before entering Class D airspace.

Q

What is provided in Class C airspace, that is not provided in Class D?

A

Radar separation.

48
Q

What is the standard shape and size of Class C airspace?

A

An inner circle of 5 NM, normally from the surface to 4,000’ AGL, unless it says otherwise. And, an outer circle from 5 NM to 10 NM, normally from 1200’ AGL to 4,000’ AGL, or as shown on the chart. Then, an outer area, which is not shown on the chart, of 20 NM radius, in which you should call ATC.

A

Contact approach control.

50
Q

How is Class B airspace shown on a chart?

A

Solid blue lines.

51
Q

What do you need to enter Class B airspace?

52
Q

What is the standard size and shape of Class B airspace?

A

It differs; you have to look on the chart.

53
Q

Near the airport, how far down does Class B airspace descend?

A

All the way down to the surface.

54
Q

What happens to the floor of Class B airspace as you leave the airport?

A

Logbook endorsement within past 90 days, ground and flight instruction in specific Class B airspace and at specific Class B airport.

57
Q

Where is Class A airspace?

A

48 contiguous states, and parts of Alaska. 18,000’ MSL, up to and including FL600. This includes the airspace overlying the waters within 12NM of the coast of the contiguous 48 states and Alaska.

58
Q

What are the requirements for flying in Class A airspace?

A

IFR rating, IFR equipped, IFR clearance at altitude assigned by ATC, mode C transponder.

59
Q

What is provided in Class A airspace?

A

Separation from all aircraft.

60
Q

How is a restricted area shown on a chart?

A

An R, a dash, and a number, with hash marks going around the sides.

61
Q

What is a restricted area?

A

Airspace that contains unusual and often invisible hazards such as aerial gunnery or guided missiles.

62
Q

How can you fly through a restricted area?

A

Look on the chart legend, and see when it is restricted, and from where you can get permission, if you want to enter during a restricted time.

63
Q

What is a warning area?

A

Same as a restricted area, but it is out to sea, in international territory.

64
Q

How is a warning area shown on a chart?

A

Same as a restricted area, but with a W instead of an R.

65
Q

What is an MOA?

A

A military operations area. They do military training, such as acrobatics and abrupt flight maneuvers.

66

How is an alert area shown in a chart?

A

In blue, with A and a number, surrounded by blue hash marks.

70
Q

What is a military training route?

A

A route along which the military can fly at any speed.

71
Q

How is a military training route depicted on a chart?

A

IR or VR, followed by a three or four digit number. VR = visual conditions, IR = could be instrument training flights. If it’s a four-digit number, the activity is 1,500’ AGL or below. If it’s a three-digit number, the activity could be either above or below 1,500’ AGL.

72
Q

How is a wildlife refuge shown on a chart?

A

Blue solid lines, with dotted area inside.

73
Q

What should you do when flying above a wildlife refuge?

A

It’s requested that you fly at least 2,000’ AGL above it.

Q

What does the distinct side of the blue mean on a chart?

A

Class G airspace from surface to 14,500’.

75
Q

What does the distinct side of the magenta mean on a chart?

A

Floor of Class E airspace 1200’.

76
Q

What’s a federal airway?

A

A VOR radial designated as controlled airspace, to provide traffic separation for IFR flights.

77
Q

How wide are federal airways?

A

8 NM wide.

78
Q

What is the airspace for an airway? What is the floor and ceiling?
