Airspace & Weather Minimums Flashcards
A Airspace
Altitude
18000 ft and above (Flight Level 60000ft MSL
B Airspace
Big
Big airports/airplanes
C Airspace
Crowded
Radar help to and from airport
D Airspace
Dialogue
First encounter Airport with control tower
E Airspace
Elsewhere
Airway and space between airway
G Airspace
Go for it
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.
