Class A

FL180 up to but not including FL600, 29.92

Instrument rated PPL or higher

IFR flight plan and ATC clx

4096 Mode C or S, 2-way radio, DME FL240 and above

No WX restrictions

No airspeed restriction

ATC traffic and routing


Class B

Busy, big, Boeing

Solid blue borders Typically up to 10,000 MSL and shaped and layered for arrival corridors

Have a 30 nm mode c veil

PPL or higher, sport and student with endorsement at some airports

ATC clx

4096 mode c or s, 2-way radio, VOR receiver if IFR

VFR wx mins: 3 s.m. and clear of clouds (3 classic cubs)

250 kias, 200 kias under bravo shelf

ATC separation and routing for all a/c


Class C

Think Callsign

Solid magenta line typically up to 4000 agl (charted in MSL) with inner core diameter of 5 NM and outer of 10 NM and outer boundary of 20 nm (not charted and not regulated)

PPL or higher unless sport or student has endorsement

ATC clx with callsign or tail#. For example, if ATC says "aircraft calling standby" you are not cleared in. If ATC says "Tail # or C/S standby" then you may continue unless directed to remain outside airspace.

Vfr WX mins: 3 sm, 1000 ft above, 500 below, 2000 laterally

200 kts within 4nm of airport

ATC IFR traffic separation and VFR traffic advisories as able

Caution, may be VFR traffic without transponder under shelf and surrounding


Class D

Think Dialogue

Blue segmented line typically 2500 agl and 4nm diameter or can be shaped to correspond with IAP if available

PPL or higher or sport/student pilot with endorsement

2 way communications with intentions required to enter even if the say "aircraft calling standby" unless specifically directed to stay out

2 way radio only


200 kias within 4nm

IFR to IFR separation and VFR if able


Class G

Think Go for it (ultralights and LSA that don't have req equipment for controlled airspace excluding E and bush plane operations 1200 and below in mtns)

This is uncontrolled airspace but VFR WX mins still apply

Daytime 1200 agl and below=1 sm and clear of clouds (1 classic cub)

Daytime and above 1200 agl =1 sm 1000 above 500 below 2000 laterally (1-152s)

Nighttime no above and below 1200 agl =3-152s

Above 10,000 MSL is 5-f111s unless within 1200 agl then above applies


Class E

Think Everyone

Starts at 1200 agl unless depicted otherwise goes up to 17,999 MSL

At and above14,500 to 17,999 is class E unless within 1,500 ft AGL (Tall mountains such as in AK)

Depicted with blue shading. Dark side abuts to class G and light side is towards an airway or controlled airspace

If magenta shading then E starts at 700 agl (transition area next to Class D airports with IAP)

Magenta segmented line depicts class E to surface

No specific pilot certificate required

No entry req such as ATC clx

Plane needs 4096 transponder if above 10,000 MSL unless within 2,500 agl


VFR WX mins: Above 10,000 msl = 5 f-111s ( 5sm, 1000ft above, 1000 below and 1 sm laterally)

IFR routing and separation, VFR traffic advisories if able
