Question 7

Which airspace requires prior authorization from ATC for Part 107 operations?

Accepted Answer

14 CFR § 107.41 requires remote pilots to obtain prior authorization before operating in Class B, Class C, Class D, or within the lateral boundaries of the surface area of Class E airspace designated for an airport.

Question 8

You see a magenta shaded vignette (faded band) on the sectional chart. This indicates that Class E airspace begins at:

Accepted Answer

A magenta vignette (shaded band) indicates that controlled Class E airspace begins at 700 feet AGL inside the band. Outside the band, it typically begins at 1,200 feet AGL.

Question 9

A dashed magenta line on a sectional chart indicates:

Accepted Answer

A dashed magenta line indicates Class E airspace designated for an airport that begins at the surface.

Question 10

What is the standard vertical limit of Class D airspace?

Accepted Answer

Class D airspace typically extends upward from the surface to 2,500 feet above the airport elevation (AGL).

Question 11

You are looking at a sectional chart and see '110/SFC' inside a solid blue area. What does this mean?

Accepted Answer

In airspace notations on charts, altitudes are given in hundreds of feet MSL. '110' means 11,000 feet MSL. 'SFC' means Surface. Thus, Class B is from Surface to 11,000 MSL.

Question 12

A Military Operations Area (MOA) is depicted on a sectional chart by:

Accepted Answer

MOAs are depicted with magenta hashed lines (comb-like teeth pointing inward) and are identified by name.

Question 13

Can you fly a drone in a Restricted Area (e.g., R-2501)?

Accepted Answer

Restricted areas denote the existence of unusual, often invisible hazards (like artillery firing). Operations are prohibited unless authorized by the using/controlling agency or if the area is 'cold' (not active).

Question 14

Prohibited Areas (e.g., P-40 over Camp David) indicate:

Accepted Answer

Prohibited areas are established for security or other reasons associated with the national welfare. Flight of aircraft (including UAS) is prohibited.

Question 15

Question 17

Alert Areas (e.g., A-211) are depicted to inform pilots of:

Accepted Answer

Alert Areas advise pilots that a high volume of pilot training or unusual activity is taking place. Pilots are responsible for collision avoidance.

Question 18

Warning Areas (e.g., W-50) are similar to Restricted Areas but are located:

Accepted Answer

Warning areas extend from 3 nautical miles outward from the coast of the U.S. The US government does not have sole jurisdiction over international waters, so it 'warns' rather than 'restricts'.

Question 19

You see a grey line labeled 'IR15' on a sectional chart. This represents:

Accepted Answer

IR and VR routes are Military Training Routes. IR indicates Instrument Flight Rules. The number '15' (2 digits) means one or more segments are above 1,500 feet AGL. (Note: 4 digits means at or below 1,500 AGL).

Question 20

In a Military Operations Area (MOA), if the area is active, you:

Accepted Answer

VFR aircraft (including drones) are not restricted from flying through an active MOA, but it is advised to exercise extreme caution due to high-speed military activity. Contacting the controlling agency for status is best practice.

Question 21

Class C airspace generally consists of a surface area with a 5 NM radius, and an outer shelf with a _____ radius.

Accepted Answer

The standard Class C shape is an upside-down wedding cake. The inner core is 5 NM radius. The outer shelf is a 10 NM radius.

Question 22

Accepted Answer

The outer shelf of Class C typically starts at 1,200 ft AGL. If you are at 100 ft AGL beneath it, you are in the uncontrolled Class G airspace below the shelf (assuming no other overlays). Authorization is not required for Class G.

Question 24

What does a flag symbol indicate on a sectional chart?

Accepted Answer

A flag symbol marks a visual checkpoint used by manned aircraft pilots to report their position to ATC. Drones should exercise caution near these points due to higher traffic.

Question 25

On a sectional chart, airport elevation is given in:

Accepted Answer

Chart elevations, including airport elevations and obstruction heights, are given in Mean Sea Level (MSL). Obstructions typically list AGL in parentheses below the MSL height.

Question 26

You see an airport symbol with 'RP 23' near it. What does this mean?

Accepted Answer

RP stands for Right Pattern. Standard traffic patterns are left turns. 'RP 23' indicates that for runway 23, pilots should make right turns.

Question 27

The numbers '45' over 'SFC' inside a magenta dashed circle indicate:

Accepted Answer

A magenta dashed line indicates Class E surface area. The notation '45/SFC' indicates the vertical limits are from the surface up to, but not including, 4,500 feet MSL. (Note: Dashed magenta is Class E Surface; dashed blue is Class D. If the circle is dashed magenta, it's E).

Question 28

A small blue circle with a star on top inside indicates:

What does the notation 'CT 118.5' near an airport symbol mean?

Accepted Answer

CT stands for Control Tower. The frequency listed is the primary frequency for contacting the tower.

Question 31

You see a symbol 'C' inside a circle following a frequency (e.g., 122.8 C). This indicates:

Accepted Answer

The 'C' in a circle symbol denotes the Common Traffic Advisory Frequency (CTAF), used for self-announcement at non-towered airports.

Question 32

A parachute symbol on a chart indicates:

Accepted Answer

A parachute icon indicates a parachute jumping area. Remote pilots should exercise extreme caution.

Question 33

You wish to fly 100 feet above a grain elevator that is 200 feet tall. The grain elevator is in Class G airspace. What is the maximum altitude allowed?

Accepted Answer

While Part 107 allows flying 400 feet above a structure, you only asked to fly 100 feet above it. The max *allowed* by regulation would be 600 ft AGL (200 structure + 400 allowance). However, the specific flight plan is 300 AGL. The question asks 'maximum altitude allowed' by regulation in this scenario? 14 CFR 107.51(b) allows 400 feet above the structure. 200 + 400 = 600 feet AGL. BUT if the answer options don't have 600... wait. Let's re-read carefully. 'What is the maximum altitude allowed?' Options: 300, 400, 1200, Not permitted. The *absolute* regulatory max is 600. If 600 isn't an option, this might be a trick question or I should provide better options. Let's adjust options to be clear. New options: 400 AGL, 600 AGL, 200 AGL, 1200 AGL. Correct is 600 AGL.

Question 34

You are 4 miles from a Class D airport but your drone flight will remain below 200 feet AGL. The Class D airspace extends from the surface to 2,500 AGL. Do you need authorization?

Accepted Answer

Class D airspace typically extends from the surface. If you are within the 4 NM radius (lateral boundary), you are in controlled airspace regardless of altitude (until the ceiling). Authorization is required.

Question 35

Controlled airspace generally requires:

Accepted Answer

The defining characteristic of controlled airspace (B, C, D, E Surface) for remote pilots is the requirement for ATC authorization prior to operation.

Question 36

What is the floor of Class E airspace when depicted by a blue shaded vignette (faded band) on a sectional chart?

Accepted Answer

A blue shaded vignette indicates Class E airspace begins at 1,200 feet AGL. (Note: Blue vignette is rare in many parts of the US now, often defaulting to 1200 everywhere outside magenta, but if depicted, blue vignette usually differentiates from 14,500 or other floors. Wait. Actually, standard Soft Blue Vignette indicates Class E starts at 1,200 AGL *inside* the band? No. Standard convention: Magenta Vignette = 700 AGL. Blue Vignette = 1,200 AGL (where it differs from surrounding). In much of the US, 1,200 is default. Blue vignette is used to show E starting at 1,200 where it might otherwise be higher (like 14,500).)

Question 37

A 'TFR' stands for:

Accepted Answer

TFR stands for Temporary Flight Restriction. Drones are prohibited from flying in TFRs (e.g., VIP movement, wildfires, stadium events).

Question 38

Where can you check for active TFRs?

Accepted Answer

Official sources for TFRs include the FAA's TFR website and Flight Service (Leidos).

Question 39

The floor of Class E airspace above a Federal Airway (Victor Airway) is typically:

Accepted Answer

Federal Airways (Victor Airways) are Class E airspace that typically extend from 1,200 feet AGL up to, but not including, 18,000 feet MSL.

Question 40

An airport beacon showing White and Green flashes indicates:

Accepted Answer

Civilian land airports are identified by a rotating beacon emitting alternating white and green flashes.

Question 41

An airport beacon showing Two White flashes followed by a Green flash indicates:

Accepted Answer

Dual peaked (two quick) white flashes between green flashes identifies a military airport.

Question 42

You need to fly in Class B airspace. How can you get authorization?

Accepted Answer

Part 107 authorization for controlled airspace must be obtained via LAANC (Low Altitude Authorization and Notification Capability) or the FAA DroneZone web portal. Direct phone calls or radio contact are not permitted methods for standard authorization.

Question 43

What does a number like '345' (in italics) indicate next to an obstruction symbol?

Accepted Answer

Numbers next to obstructions indicate elevation. The top (bold) number is MSL. The number in parentheses (often italics or smaller) is AGL. Wait. Standard chart: Bold is MSL. Parentheses is AGL. The question says '345' (in italics). Usually, the AGL number is in parentheses. Let's clarify the question to match the standard format: 'The number in parentheses below the bold elevation figure indicates...'. But if sticking to the prompt: '345' in parentheses represents height AGL.

Question 44

A National Security Area (NSA) is depicted with a broken magenta line. Pilots are:

Accepted Answer

Pilots are requested to voluntarily avoid flying through NSAs to increase security and safety of ground facilities. (Though sometimes they can be made Prohibited by NOTAM, the standard NSA is voluntary).

Question 45

You are flying near an airport with a Class E surface area (dashed magenta). The weather is 2 SM visibility. Can you fly without a waiver?

Accepted Answer

Regardless of airspace class, 14 CFR § 107.51(c) requires a minimum of 3 statute miles flight visibility for all operations.

Question 46

If a Military Training Route (MTR) has four digits (e.g., VR1234), it generally means:

Accepted Answer

MTRs with four digits are flown at or below 1,500 feet AGL. (Routes with 3 or fewer digits have at least one segment above 1,500 feet AGL).

Question 47

The vertical limit of Class C airspace is usually:

Accepted Answer

Class C airspace typically extends to 4,000 feet above the airport elevation.

Question 48

Class G airspace is:

Accepted Answer

Class G is the portion of the airspace that has not been designated as Class A, B, C, D, or E. It is uncontrolled.

Question 49

Which chart is most appropriate for a remote pilot operating a small UAS?

Accepted Answer

VFR Sectional Charts provide the necessary visual landmarks, airspace boundaries, and obstacle data required for VFR (Visual Flight Rules) navigation used by drones.

Question 50

You see a symbol on the chart that looks like a rocket. This indicates:

Accepted Answer

A rocket symbol indicates a Space Launch Activity Area. Pilots should avoid these areas when active.

Question 51

Refer to a Sectional Chart. You are flying at 1,500 feet MSL in an area where the terrain elevation is 1,200 feet MSL. You are crossing a magenta vignette. What airspace are you in?

Accepted Answer

You are at 300 feet AGL (1500 MSL - 1200 Terrain). The magenta vignette indicates Class E starts at 700 feet AGL. Since you are below 700 feet AGL, you are in Class G airspace.

Question 52

What is the floor of Class E airspace at an airport with a dashed magenta line surround?

Accepted Answer

A dashed magenta line indicates Class E airspace designated for an airport starting at the Surface. Authorization is required here.
