What does NOTAMs stand for?
Notices to Air Missions
What does Notices to Air Missions (NOTAMs) mean?
A written notification issued to pilots before a flight, advising them of circumstances relating to the state of flying
NOTAM info is classified into 5 categories:
- NOTAM (D) or distant
- Flight Data Center (FDC) NOTAMs
- Pointer NOTAMs
- Special Activity Airspace (SAA) NOTAMs
- Military NOTAMs
FDC NOTAMs are issued by the ________ and contain ________ info such as temp flight restrictions or an amendment to instrument approach procedures
National Flight Data Center (NFDC); regulatory
Pointer NOTAMs highlight or point out another NOTAMs such as the issuance of an __________ or ______
FDC or NOTAM (D); it helps to cross reference info
Military NOTAMs pertain to _______ NAVAIDs/airports that are part of the NAS
U.S. Air Force, Army, Navy, and Marine
What is NAVAID?
A navigational device in an aircraft, ship, or other vehicle
SAA NOTAMs are issued when _______ will be active outside the published schedule time and when required by the published schedule
Special Activity Airspace
What does TFR mean?
Temporary Flight Restriction
Common TFRs that relate to sUAS operations include:
- Presidential
- Emergency response - forest fires etc
- Standing TFRs - go in and out of effect
What is AIM?
Aeronautical Information Manual
The _______ is the official guide to basic flight information and ATC procedures, which is issued yearly with ongoing revisions
AIM

No fought under VFR is authorized in ____________
Class A airspace
________ airspace consists of controlled airspace extending upward from the surface or higher up to specified altitudes
Class B
_______ is outlined in blue in the Sectional Chart, is labeled with its delimiting arcs, radials, and altitudes
Class B
Class ______ is depicted by solid magenta lines
Class C
Class C
The inner surface area has a radius of 5 NM and extends from the surface up to 4,000 ft above the airport.
The outer shelf area has a radius of 10 NM and extends vertically from 1,200 AGL up to 4,000 ft above the primary airport
_______ airspace extends upward from the surface to approx. 2,500ft AGL
Class D
Class D airspace may include one or more airports and is normally _________ in radius centered around a designated airport.

1,200
All airspace from _____ to ______ is Class ___
14,500 ft to 17,999 ft; Class E
Class ____ typically extends from the surface to the base of overlying controlled (class E) airspace
Class G
Class G airspace is normally _____ or ______ ft AGL

Prohibited Areas
Are blocks of airspace within which the flight of aircraft is prohibited. White House and US Capitol Building
Restricted Areas
Denote the presence of unusual, often invisible, hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles.
Warning Areas
Similar to restricted areas but located in international airspace
Alert Areas
May contain high volume of pilot training activities or an unusual type of aerial activity
Military Operations Areas (MOAs)
Consist of airspace established for the purpose of separating certain military training activities from IFR traffic.
Military Training Routes (MTRs)
Conducted at low-altitude, high speed training. Generally below 10,000 ft at speeds in excess of 250 knots
The lines running east and west, parallel to the equator are called parallels of
Latitude
Lines called meridians of _________ are drawn from pole to pole
Longitude
What type of flights are being conducted as indicated by IR678
IFR military training route above 1,500 feet AGL
