Uncontrolled airspace
The airspace system designations used throughout the United States
standardizes airspace classifications with other countries.
Controlled airspace
A B C D E
Uncontrolled airspace
G
Class E airspace with a floor of 1200 feet AGL on chart is marked by
Fuzzy side of blue (floor of controlled airspace 1200 feet)
Class E airspace with a floor of 700 feet AGL on chart is marked by
Fuzzy side of magenta (floor of controlled airspace 700 feet)
Class E airspace all the way to ground on chart is marked by
Magenta segmented line
G airspace is from the surface up to
14500 feet MSL
A airspace starts at
18000 feet MSL
The VFR pilot flying in Class G airspace
has reduced cloud and visibility restrictions because it’s unlikely that IFR traffic will be operating in Class G airspace.
You know when looking at a chart that the floor of Class E airspace is 700 feet AGL when it’s within
the fuzzy side of the magenta vignette.
Class D airspace is marked on a chart by
- Blue segmented circle.
- To fly in you must have a dialogue.
- Has control tower.
- Core area = 5 statute miles(4.4 Nautical miles)
- Controlled airspace all the way to the ground.
D airspace vertical limits
Normally surface to 2500 feet above airport elevation
The lateral dimensions of Class D airspace are based on
the instrument procedures for which the controlled airspace is established.
Class D requirement for communication
VHF transmitter and receiver.
What is considered clearance into class D airspace
Control tower acknowledges aircraft’s call sign. (N number) unless told to stay clear.
Airspace at an airport with a part-time control tower is classified as Class D airspace only
when the associated control tower is in operation.
Unless otherwise authorized, two-way radio communications with Air Traffic Control are required for landings or takeoffs at all towered airports
regardless of weather conditions.
A non-tower satellite airport, within the same Class D airspace as that designated for the primary airport, requires radio communications be established and maintained with the
primary airport’s control tower.
When a control tower, located on an airport within Class D airspace, ceases operation for the day, what happens to the airspace designation?
The airspace reverts to Class E or a combination of Class E and G airspace during the hours the tower is not in operation.
Class C airspace on a chart is marked by
A solid magenta line.
Inner circle or surface area for Class C is normally
4000 feet AGL
Outer circle or shelf area for Class C is normally
1200 to 4000 feet AGL
The normal radius of the procedural Outer Area of Class C airspace is normally
20 nautical miles.
Required equipment for Class C
- Two-way radio.
- Mode C transponder.
- Altitude encoding.
Two-way radio communication must be established with the Air Traffic Control facility having jurisdiction over the area prior to entering which class airspace?
Class C.
All operations within Class C airspace must be in
an aircraft equipped with a 4096-code transponder with Mode C encoding capability.
Under what condition may an aircraft operate from a satellite airport within Class C airspace?
The pilot must contact ATC as soon as practicable after takeoff.
Which initial action should a pilot take prior to entering Class C airspace?
Contact approach control on the appropriate frequency.
Class B airspace is marked with what on a chart?
Dark blue solid lines. Must have clearance to enter. "Cleared into class B airspace"
Class B requirements
- Private Pilot.
- Student with endorsement.
- Communications radio
- Able to navigate
- 4096 transponder with Mode c.(within 30 NM up to 10000ft MSL)
- An encoding altimeter
Class A requirements
- IFR rated & current
- IFR equipped
- IFR clearance at altitude assigned by ATC
- Transponder w/Mode C
In which type of airspace are VFR flights prohibited?
Class A.
Federal Airway width, airspace type, elevation
8 Nautical Miles, controlled airspace, class E floor 1200 AGL up to and including 17999’ MSL
What on a chart divides Floor of controlled airspace
Blue zipper line.
Restricted areas marked
with inward blue hashes.
Military Operations Area MOA is marked
with inward magenta hashes. (Flight Maneuvers)
What hazards to aircraft may exist in areas such as Devils Lake East MOA?
Military training activities that necessitate acrobatic or abrupt flight maneuvers.
What action should a pilot take when operating under VFR in a Military Operations Area (MOA)?
Exercise extreme caution when military activity is being conducted.
Responsibility for collision avoidance in an alert area rests with
all pilots.
4 digit Military Training route(MTR)
Below 1500’ AGL
3 digit Military Training route(MTR)
Above or below 1500’ AGL
IR MTR
instrument conditions allowed
VR MTR
Visual conditions only
What type of military flight operations should a pilot expect along IR 644?
IFR training flights above or below 1500’ AGL at speeds in excess of 250 knots.
Blue border with blue dots
protected wildlife area; fly no lower than 2000’ AGL
Special Flight Rules Area: one around D.C.
jagged line circle tinted red
D.C. SFRA requirements
- File IFR or SFRA flight plan for VFR
- Mode C transponder with assigned code
- Two-way radio communications
No speed limit
10000’ and above MSL
The basic VFR minimum visibility at night for Class G, E, D, and C airspace below 10000’ MSL is 3 statute miles. An exception to that minimum is when below 1200’ above the surface and the visibility is at least 1 but less than 3 statute miles
in Class G airspace clear of clouds when operating in an airport traffic pattern within 1/2 mile of the runway.
Normal VFR operations in Class D airspace with an operating control tower require the ceiling and visibility to be at least
1000’ AGL and 3 miles.
No person may take off or land an aircraft under basic VFR at an airport that lies within Class D airspace unless the
ground visibility at that airport is at least 3 miles.
The basic VFR weather minimums for operating an aircraft within Class D airspace are
1000-foot ceiling and 3 miles visibility.
An airport’s rotating beacon operated during daylight hours indicates
that weather at the airport located in Class D airspace is below basic VFR weather minimums.
SVFR
Special VFR 1 mile viz
A special VFR clearance authorizes the pilot of an aircraft to operate VFR while within Class D airspace when the visibility is
at least 1 mile and the aircraft can remain clear of clouds.
What is the minimum weather condition required for airplanes operating under special VFR in Class D airspace?
1 mile flight visibility.
What are the minimum requirements for airplane operations under special VFR in Class D airspace at night?
The pilot must be instrument rated, and the airplane must be IFR equipped.
No person may operate an airplane within Class D airspace at night under special VFR unless the
airplane is equipped for instrument flight.
What ATC facility should the pilot contact to receive a special VFR departure clearance in Class D airspace?
Air Traffic Control Tower.
