On a sectional chart, a symbol showing 'MOA' with a defined boundary indicates:
Answer: A Military Operations Area where high-speed military training may occur
MOA stands for Military Operations Area, where military training activities such as air combat maneuvers and low-altitude tactics may occur, posing hazards to civilian aircraft and drones.
What does a group obstruction symbol (multiple towers clustered together) on a sectional chart depict?
Answer: A wind farm or multiple towers within a small area
A group obstruction symbol on a sectional chart represents multiple obstacles (commonly wind turbines or communication towers) located within a small geographic area.
A remote pilot consults a sectional chart and finds the notation 'SFC-4000' within a Class C airspace ring. What does this mean?
Answer: The inner ring extends from the surface to 4,000 feet MSL
In Class C airspace notation, SFC-4000 means the airspace begins at the surface and extends up to 4,000 feet MSL, typically found in the inner circle around the primary airport.
What are the two numbers shown next to an airport's ATIS or AWOS/ASOS frequency on a sectional chart?
Answer: The AWOS type number and its broadcast frequency
Sectional charts show the AWOS/ASOS type designation (e.g., AWOS-3) and the broadcast frequency so pilots can tune in for automated weather observations.
A remote pilot notes 'W' followed by a number (e.g., W-50) on a sectional chart over the open ocean area. What does this denote?
Answer: A Warning Area over international waters where foreign military or hazardous operations may occur
Warning Areas (W-XXX) are depicted on sectional charts over international waters and contain activities that may be hazardous to non-participating aircraft, but the FAA lacks authority to restrict access.
On a sectional chart, what does a shaded area with 'MTR' and a number below 1,500 feet AGL indicate?
Answer: A Military Training Route flown at low altitude and high speed
MTR designations on sectional charts mark Military Training Routes used by military aircraft at high speeds, and routes below 1,500 AGL are depicted with four-digit route numbers.
A remote pilot studying a sectional chart notes that a Victor Airway (e.g., V-105) is labeled with the number '5500' above a line and '3900' below it. What do these numbers represent?
Answer: MEA of 5,500 feet and MOCA of 3,900 feet for that airway segment
On a Victor Airway, the upper number is the Minimum Enroute Altitude (MEA) ensuring obstacle clearance and navigation signal reception, while the lower number is the Minimum Obstruction Clearance Altitude (MOCA).
