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
