A108 Airspace Flashcards
What is a Transponder?
Beacon (squawk), 4 digit code
Mode C, “Squawk Altitude”
broadcasts pressure altitude
to Air Traffic Control (ATC)
ADS-B integrated into the
transponder
In general, airspace that requires a transponder also requires ADS-B out at a minimum
What is ADS-B?
A surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked.
Below 10000 MSL is restricted to what speed?
250 KIAS or below
At or above 10000 MSL is restricted to what speed?
Mach 1
VFR visibility below 10k MSL
3 SM visibility
3, 5, 1, 2 refers to what restrictions for VFR?
Below 10,000’ MSL
* VFR Visibility: Three statute miles
* VFR Cloud Clearance:
500 feet below
1,000 feet above clouds
2,000 feet horizontal of clouds
Controlled airspace consists of?
- Class A

Who flies is class A airspace?
IFR flights ONLY
Where is class A airspace?
Above All!
18000 MSL to FL600
Who flies is class B airspace?
IFR and VFR
Big BUSY airports
Is a clearance required for Class B?
YES
What are the minimum pilot qualifications for class B?
Private Pilot, Restricted Student
How many Class B airspaces are there in the US?
37
Class B is generally from the surface to ________ MSL
with tiered layers.
10,000’
What is Mode C Veil?
- Usually, the airspace within 30 nm of the primary airport within the Class B airspace
- Extends from the surface to 10,000’ MSL
- Must have an operating Transponder with Mode C (altitude encoding) to fly inside this veil
- Automatic Dependent Surveillance-broadcast (ADS-B)
Where is Class C Airspace?
Crowded City Airport
Is clearance required for Class C Airspace?
Two-way dialogue is required
What is the current number of Class C airspaces in the US?
122
Is a clearance required for Class D?
Two-way dialogue
Where is Class D airspace?
“Dwarf” Cities
Class D altitudes?
Surface to 2500 AGL
Class D airspace at airports with a part-time control tower may revert to _________ when the tower is not in operation.
Class E
Where is Class E Airspace?
“Everywhere else”
Is clearance required for Class E?
No
What Class of airspace fills in all the gaps between all other types of airspace?
Class E
What is above Class A airspace?
Class E
Is class E controlled airspace?
Yes
Hard side of fading blue lines would depict Class E airspace starting at _________
14,500’ MSL
Slide 34 A108
Where is Class G?
On the ground, beneath Class E
Is Class G a controlled airspace?
NO
What are prohibited airspaces used for?
Are established for security or other reasons associated with the national welfare. Aircraft are forbidden to enter Prohibited Areas.
What does a Restricted Airspace depict?
Denote the existence of unusual, often invisible hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles.
What are Military Operating Areas (MOA)?
Military Operations Area (MOA) consists of airspace of defined vertical and lateral limits established for the purpose of separating
military training activity from IFR traffic.
Are VFR aircraft allowed in a MOA?
Yes, however, pilots should be alert since training activities may include
acrobatic flight and abrupt maneuvers.
What is an Alert Area?
Established in areas with a high volume of pilot training or unusual type of aerial activity.
What are the two types of Military Training Routes? (MTR)
‘IR’ are for IFR flights
‘VR’ are for VFR flights
What are National Security Area (NSA)?
- Established around areas requiring special security precautions
- Pilots are requested to avoid flight below a specified altitude within the NSA
