CONTROL TOWER CLOSES- reverts to E or G or combo
Class E
Control tower not in operation, extension to surface area, transition area, enroute domestic, federal airways, offshore, above FL 600
Student pilot min
Radar beacon and ADS-b out if above 10K
Transition areas- for ifr approach either 700 or 1200 and up
2-way communication with a tower is required

Spécial VFR
If flight can remain clear of clouds with 1SM ground visibility
Can be requested with tower if won’t disrupt IFR OPERATIONS only during daytime
Class G
Uncontrolled airspace
Surface to base of E
2-way radio comm still required
Does not exceed 14500 ft MSL
Traffic pattern at night allowed if vis above 1SM and clear of clouds if within one half mile of runway
Prohibited areas
Established for security and national welfare, no flying allowed
Restricted area
Subject to restrictions, unusual sometimes invisible hazards such as artillery, cannot enter without permission from controlling agency
Warning area
3NM outward from the coast
May be hazardous
MOA
Military Operating Area
Exercise extreme caution
Contact FSS within 100NM FOR HOURS OF OPERATION
Alert Area
High volume of pilot training or aerial activity
Be alert
Controlled Firing Area
CFA
NOT DEPICTED
Could be hazardous
Firing stops when planes spottrd
National Security Area
NSA
Pilots asked to voluntarily avoid flying
“Other airspace”
Local airport advisory
Military training route
Temporary flight restrictions
Parachute jump aircraft operations
Published VFR
Terminal radar service area
Special air traffic rules
Military Training Routes
Below 1500 VFR 4-digit
Above 1500 IFR 3-digit
Parachute jump
Info in chart supp and on sectional charts

To avoid, fly through, under complex airspace
VFR Terminal Area Planning Charts
TRSA
Solid black line
Not part 71 or 91
Participation voluntary but urged
Primary Airports become class D
Special Air Traffic Rules
Rules for operations in specific areas designated in code of federal regulations
Special Flight Rules Area
Flight subject to rules set forth in Part 93
ADIZ
Air Defense Identification Zone
Airspace where identification, location, and control of aircraft is required in interest to national security
Need flight plan, two way radio, transponder, position reports,
Land based could be intercepted by fighter jets
