Study Notes

Airspace Classification and Operating Requirements

When a Class D control tower ceases operations, the airspace designation reverts to Class E or a combination of Class E and G.
Class D airspace is in effect only when the associated control tower is operational, regardless of weather conditions.
The lateral dimensions of Class D airspace are determined by the instrument procedures established for the area.
A blue segmented circle on a sectional chart represents Class D airspace.
Airports with control towers (underlying Class B, C, D, E, or G airspace) are depicted in blue on sectional charts; those without control towers are shown in magenta.
Information about parachute jump sites is available in the Chart Supplement.

NOTAMs and Preflight Planning

Remote pilots check NOTAMs online or via phone for official briefings before flights.
The Fentress NALF Airport is classified as Class E airspace from the surface.
Restricted areas indicate unusual hazards, such as military gunnery or missiles.
Chart supplements provide information on parachute and glider operations at specific airports.

Airspace Specifications and Hazards

The base of Class B airspace at Lakeview Airport is 3,000 feet MSL, with its top at 11,000 feet MSL.
Airspace over Fort Worth Meacham is Class D, extending from the surface to 3,200 feet MSL.
Class E airspace exists from the surface to 700 feet AGL around Barnes County Airport, with Class G airspace below it.
Gila Bend Airport (GXF) is surrounded by Class D airspace, indicated by a dashed blue line.

Military Operations and Training Routes

Military Operations Areas (MOAs) facilitate military training, often involving acrobatic maneuvers; vigilance is required from VFR traffic.
Military training routes (MTRs) can present hazards to small unmanned aircraft, especially if they operate below 1,500 feet AGL.
Restricted areas are indicated on charts with an "R" followed by a number, denoting specific restrictions.

Flight Visibility and Operational Information

The required visibility for remote pilots operating near designated airports must be at least 3 statute miles.
The Savannah Class C airspace shelf area has a floor at 1,300 feet MSL.
Flight operations within designated areas may require checking with legends on sectional charts for additional information on airspace.

General Flight Operations

For flights through various airspaces, ATC authorization may not be necessary if operating in Class G airspace away from airports.
The NTAP includes current NOTAMs that are relevant for an extended period, available if specifically requested during weather briefings.
