Airspace Flashcards
Class A Airspace
Above 18,000 MSL; covers the whole nation; above everything else
PG allowed airspace
Nearly all of E and all of G
Class B Airspace
Big, busy airports. Not usually standardized alt/geo; can tell by concentric circles with altitudes in FLIGHT LEVELS appearing in fractions
Mussel Rock: it’s in Class B airspace. Why can we fly there?
There’s a subsection in the Class B airspace around SFO - called a keyhole - which amends the floor of the Class B airspace to 1500’
Class C Airspace
Commercial airports, not as big as Big Busy Bs; similar situation but not as big of a deal. Above and around generally okay.
Blue lines
Class B
Magenta lines
Class C
Consequence of violation: Class B
Big, Bad, Better not
Class D Airspace
Dinky, dime-sized, small city airports sometimes. Same as B and C - don’t fly without permission; customary/good idea to contact ATC at a class D if you’re near or especially above
Blue field with dashed blue lines around
Class D
Class E Airspace
Everywhere, “everything else” (not really); stuff that isn’t other airspace. We can fly in most of E, except Surface Class E
Surface Class E
This one is stupid - it’s basically Class D within a Class E area. Goes to surface and extends up upside-down cake style
Magenta dashed lines
Surface Class E
Class G Airspace
Ground airspace; contour layer above the ground, upper level is usually floor of overriding class E
Restricted Area
Clearly marked, hazardous for some reason, may be an on/off situation, check
