Q

What is the Class B Mode C Veil? What does it look like on a VFR sectional?

A

It’s a 30NM area that surrounds Class B airspace (from the surface to 10,000’ MSL) where all aircraft operating in this area must have a Mode-C transponder and ADS-B out.

It’s a solid magenta line around the Class B airport.

Q

Class C Dimensions

A

Generally that airspace from the surface to 4,000’ above the airport elevation (charted in MSL) surrounding airports that have an operational control tower and serviced by an radar approach control

  • 5NM radius core from the surface to 4,000’ AGL and 10NM shelf from 1,200’ AGL up to 4,000’ AGL

44
What is a special use airspace?
Airspace wherein activites must be confined because of their nature or limitations are placed on aircraft operations that are not apart of those activities
45
Which special use airspaces are depicted on aeronautical charts?
All special use airspaces are depicted **except for controlled firing areas**
46
What are the different types of special use airspaces?
* Military Operations Area (MOAs) * Controlled Firing Area (CFAs) * Prohibited Areas * Restricted Areas * Alert Areas * Warning Areas * National Security Area (NSAs) ## Footnote MCPRAWN
47
Military Operating Areas (MOAs)
Consists of an airspace with defined lateral and vertical limits **established for the purpose of separating certain military training activites** ## Footnote Magenta ticked outline with the MOA named
48
Is VFR flight allowed in MOAs?
VFR flight is permitted in a MOA but should exercise extreme caution
49
Controlled Firing Areas
Airspace that **contains activities that, if not conducted in a controlled environment, could be hazardous to nonparticipating aircraft** ## Footnote Not charted on VFR sectionals
50
Is VFR flight allowed through Controlled Firing Areas?
Yes; activities will be suspended immeadiately when a spotter aircraft, radar, or lookout indicate that an aircraft might be approaching the area
51
Prohibited Areas
Airspace with defined dimensions **where the flight of aircraft is prohibited** due to security or other reasons due to national welfare ## Footnote Blue ticked outline with the Prohibited Area name
52
Restricted Areas
Airspace in which the flight of aircraft, while not wholly prohibited, is subject to restrictions. **Restricted areas denote the existence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles**
53
Is VFR flight allowed in Restricted Areas?
VFR flights are allowed but pilots should check with the controlling agency to be aware if the airspace will be active or not
54
Alert Areas
Areas of airspace that may contain high volue of pilot training or an unusual type of aerial activity
55
Is VFR flight allowed through Alert Area?
Yes
56
Warning Areas
Airspace of defined dimensions that **extend 3NM outward from the coast of the US that contains activity that may be hazardous to nonparticipating aircraft** It's purpose is to warn nonparticipating pilots of potential danger ## Footnote Blue ticked outline with the Warning Area name
57
National Security Areas
Consists of an airspace with defined lateral and vertical limits **established at locations where there is a requirement for increased security and safety of ground facilities ** ## Footnote Depicted as dark magenta blocked lines
58
Is VFR flight allowed in National Security Areas?
Flight is permitted but pilots are requested to voluntarily avoid flying through the area
