FAA 107 Sectional Chart Reading & Navigation 5

Question 1

On a sectional chart, a symbol showing 'MOA' with a defined boundary indicates:

Accepted Answer

A Military Operations Area where high-speed military training may occur

Answer

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.

Question 2

What does a group obstruction symbol (multiple towers clustered together) on a sectional chart depict?

Accepted Answer

A wind farm or multiple towers within a small area

Answer

A group obstruction symbol on a sectional chart represents multiple obstacles (commonly wind turbines or communication towers) located within a small geographic area.

Question 3

A remote pilot consults a sectional chart and finds the notation 'SFC-4000' within a Class C airspace ring. What does this mean?

Accepted Answer

The inner ring extends from the surface to 4,000 feet MSL

Answer

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.

Question 4

What are the two numbers shown next to an airport's ATIS or AWOS/ASOS frequency on a sectional chart?

Accepted Answer

The AWOS type number and its broadcast frequency

Answer

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.

Question 5

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?

Accepted Answer

A Warning Area over international waters where foreign military or hazardous operations may occur

Answer

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.
