7.0 Radio Communications and Airport Operations Part 107 Practice Quiz

• A. The CTAF is a dedicated frequency for remote pilots to notify manned aircraft of sUAS operations within 5 miles of the airport
• B. The CTAF is used exclusively by IFR aircraft to obtain clearances from the ARTCC before descending below the transition altitude
• C. The CTAF allows pilots to self-announce their positions and intentions so that other aircraft in the area can maintain situational awareness without ATC services
• D. The CTAF is used to request the automated weather observation broadcast from the airport's AWOS or ASOS system

The CTAF provides a common frequency where pilots at non-towered airports self-announce their position, altitude, and intentions (such as downwind, base, or final) so that other aircraft in the area can build situational awareness and sequence themselves safely without a controller.

• A. Cleared to land immediately; the flashing red signal replaces the standard green landing clearance during radio failures
• B. Taxi clear of the runway in use; the aircraft on the ground must exit the runway area immediately
• C. Stop; the aircraft on the ground must halt immediately and hold position
• D. Return to starting point on the airport; the aircraft on the ground must return to the ramp or last cleared position

A flashing red light gun signal directed at an aircraft on the ground means 'return to starting point on airport'; the aircraft must taxi back to its starting position and hold.

• A. UNICOM is an FAA-operated automated system that replaces the CTAF when the airport manager certifies the station is unmanned
• B. UNICOM is a military frequency that coordinates airspace reservations for sUAS operators conducting commercial operations near airports
• C. UNICOM is operated by a private entity such as an FBO and may provide advisory services including wind and runway information, fuel availability, and other non-ATC services
• D. UNICOM provides the same IFR clearance delivery service as a control tower during the hours when the control tower is closed

UNICOM is operated by a fixed-base operator (FBO) or other airport authority and provides non-regulatory advisory services including wind reports, favored runway information, and operational services such as fuel requests; it is not an official ATC service but is a practical source of airport information.

• A. The steady green signal in flight means cleared to land; the pilot may continue the approach and land
• B. The steady green signal in flight means cleared for takeoff; the aircraft should increase power and depart the airport traffic area immediately
• C. The steady green signal in flight means exercise extreme caution; other aircraft or ground hazards are present near the runway
• D. The steady green signal in flight means return to starting point; the aircraft must abort the approach and re-enter the traffic pattern

A steady green light directed at an aircraft in flight is the FAA standard signal meaning 'cleared to land'; the pilot may proceed with the approach and landing.

• A. The numbers indicate magnetic heading in tens of degrees; runway 27 is oriented toward approximately 270 degrees (west) and runway 09 toward approximately 090 degrees (east)
• B. The numbers indicate runway length in hundreds of feet; runway 27/09 is 2,700 feet long in one direction and 900 feet long in the other
• C. The numbers indicate the runway's position on the airport diagram grid; all runways are numbered sequentially in order of construction
• D. The numbers indicate the maximum allowable crosswind component in knots for operations on that runway surface type

Runway designators represent the runway's magnetic heading rounded to the nearest ten degrees and then divided by ten; runway 27 is oriented toward 270 degrees (west) and runway 09 toward 090 degrees (east); opposite ends of the same runway always differ by 18 (180 degrees).

• A. The pilot must contact the FAA command center by telephone to log the runway crossing before executing the movement
• B. The pilot must visually confirm the runway is clear, then cross without reading back the clearance because crossing clearances are self-executing under ATC rules
• C. The pilot must read back the runway crossing clearance including the runway number and taxiway, then cross after receiving confirmation from the controller
• D. The pilot must flash the aircraft's landing light three times as a visual confirmation signal before crossing any active runway

FAA regulations and ATC procedures require pilots to read back all runway crossing clearances in full, including the runway designator; the controller must hear the correct readback before the crossing is confirmed, and the pilot may cross only after the controller has acknowledged the readback.

• A. The displaced threshold indicates that the landing threshold is 600 feet from the runway end; aircraft must touch down at or beyond the solid white bar and may not land on the arrowed area, though departing aircraft may use the full pavement for takeoff
• B. The arrows indicate a stopway available only for rejected takeoff deceleration; aircraft may not land on or use the stopway for any other purpose
• C. The area with arrows is a blast pad; no aircraft may operate there under any circumstances, including takeoff rolls and landing overruns
• D. The displaced threshold marks the location of an ILS glideslope touchdown zone; aircraft must land within 200 feet of the arrows to remain on the ILS path

A displaced threshold, marked with white arrows leading to the solid white threshold bar, indicates that the landing threshold is moved from the physical end of the pavement; arriving aircraft must not touch down before the solid bar but may overfly the arrowed area on approach; departing aircraft and aircraft taxiing may use the full pavement.

• A. Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for landing and takeoff of aircraft
• B. Any unauthorized entry onto an active runway by a ground vehicle, animal, or person that requires an aircraft to execute a go-around
• C. Any aircraft that lands without ATC clearance on a runway that is not in use, regardless of whether other traffic is present
• D. Any ground vehicle that crosses a taxiway hold short line without a radio equipped with the appropriate airport frequency loaded

The FAA defines a runway incursion as any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft; this encompasses a wide range of events from potential conflicts to actual collisions.
