Lines of latitude on an aeronautical chart run in which direction and measure distance from where?
Answer: East-West, measuring angular distance north or south of the equator
Lines of latitude (parallels) run east-west and measure angular distance north or south of the equator, ranging from 0° at the equator to 90° at the poles.
On a sectional chart, one degree of latitude equals approximately how many nautical miles?
Answer: 60 nautical miles
One degree of latitude equals approximately 60 nautical miles, which is the basis for defining the nautical mile (one minute of latitude = one nautical mile).
A remote pilot wants to determine if their planned sUAS flight location requires airspace authorization. Which tool used alongside a sectional chart provides the most current authorization requirements?
Answer: The FAA's B4UFLY app or LAANC system
The FAA's B4UFLY app and LAANC (Low Altitude Authorization and Notification Capability) system provide current, dynamic airspace authorization data and can process instant authorizations for sUAS operations in controlled airspace.
Understanding the "floor" value of Class B airspace sections on a sectional chart is important for remote pilots because:
Answer: Below the floor, different airspace (often Class E or G) applies with different authorization requirements
Class B airspace floors indicate where Class B begins; below that floor, other airspace classes (Class E or G) apply, which may have different or no authorization requirements for sUAS operations.
A remote pilot planning operations near a non-towered airport should know that the standard traffic pattern altitude for propeller-driven aircraft is:
Answer: 1,000 feet AGL
Standard traffic pattern altitude is 1,000 feet AGL for propeller-driven aircraft, meaning sUAS operating near airports must be aware of this altitude to avoid conflicts with arriving and departing aircraft.
On a sectional chart, the compass rose printed around a VOR station symbol is useful to remote pilots primarily because:
Answer: Its alignment to magnetic north displays local magnetic variation at that location
VOR compass roses are aligned to magnetic north, displaying the local magnetic variation and helping pilots understand the offset between true north (shown on charts) and magnetic north (used in aviation).
When reading a sectional chart to plan a flight near an area marked with "MOA" and the associated hours of operation shown, a remote pilot should understand that a Military Operations Area (MOA):
Answer: Contains military flight activity that may pose a collision hazard, but sUAS are not legally excluded
MOAs are special use airspace where military activities occur, but unlike Prohibited or Restricted areas, sUAS are not legally barred from MOAs — however, the collision hazard requires caution and situational awareness.
