An airport is characterized as 'non-towered' when it operates without the presence of an air traffic control tower or any dedicated air traffic control (ATC) unit.
Answer: True
Explanation: This statement accurately defines a non-towered airport as one lacking an air traffic control tower or a dedicated ATC unit.
In the United States, the number of airports equipped with control towers is significantly less than the number of non-towered airports.
Answer: True
Explanation: The United States possesses a substantially larger quantity of non-towered airports compared to those equipped with control towers, with estimates indicating approximately 20,000 non-towered versus 500 towered facilities.
Airports that possess a control tower but do not offer 24/7 ATC service revert to non-towered operational procedures during the hours the tower is closed.
Answer: True
Explanation: When a control tower's operational hours conclude, the airport transitions to non-towered procedures, requiring pilots to manage operations independently.
Sedona Airport serves as an example of an airport that operates without a control tower.
Answer: True
Explanation: Sedona Airport is cited as an instance of an airport that functions without the presence of an air traffic control tower.
The fundamental characteristic defining a non-towered airport is the complete absence of an air traffic control tower or any active unit directing air traffic.
Answer: True
Explanation: The defining feature of a non-towered airport is the lack of an air traffic control tower or any operational unit responsible for managing air traffic.
What defines an airport as 'non-towered'?
Answer: It operates without an air traffic control tower or a dedicated ATC unit.
Explanation: An airport is defined as 'non-towered' by the absence of an air traffic control tower or any dedicated ATC unit responsible for managing air traffic.
How does the number of non-towered airports in the U.S. compare to those with control towers?
Answer: There are about 20,000 non-towered airports and only 500 with towers.
Explanation: The United States has a significantly higher number of non-towered airports, estimated at around 20,000, compared to the approximately 500 airports that have control towers.
What procedure applies to an airport that has a control tower but isn't open 24/7?
Answer: It follows non-towered airport procedures when the tower is closed.
Explanation: When a control tower is not operational, the airport reverts to non-towered procedures, requiring pilots to manage their own traffic separation and communication.
What is the fundamental difference in pilot responsibility at a non-towered versus a towered airport?
Answer: At towered airports, pilots receive direct instructions; at non-towered airports, they self-coordinate using procedures and radio.
Explanation: The fundamental difference lies in ATC's role: at towered airports, pilots receive direct instructions, whereas at non-towered airports, pilots must self-coordinate using established procedures and radio communication.
At non-towered airports, pilots are responsible for managing flight operations, rather than receiving direct instructions from air traffic controllers.
Answer: True
Explanation: Unlike towered airports where controllers issue directives, pilots at non-towered airports must assume responsibility for managing their operations through self-coordination and adherence to established procedures.
The operational procedures recommended for non-towered airports are not universally standardized and can differ internationally.
Answer: True
Explanation: There is no single global standard for non-towered airport procedures; specific recommendations and practices can vary significantly between countries.
The utilization of a Common Traffic Advisory Frequency (CTAF) is a principal communication method employed at non-towered airports.
Answer: True
Explanation: Common Traffic Advisory Frequency (CTAF) serves as a vital radio channel for pilots to communicate positions and intentions, facilitating self-coordination at non-towered airports.
At non-towered airports, pilots do not rely on controllers for traffic separation; instead, they manage separation through self-coordination.
Answer: True
Explanation: Pilots at non-towered airports are responsible for maintaining traffic separation through self-coordination, as there are no controllers to direct them.
CTAF is primarily used for pilots to announce positions and intentions for self-coordination, not for receiving direct ATC clearances.
Answer: True
Explanation: The primary function of CTAF is pilot self-announcement for coordination, not the issuance of ATC clearances.

UNICOM is a service primarily used for assisting aircraft with arrival, departure, and ground maneuvering information at non-towered airports, not for issuing flight plan clearances.
Answer: True
Explanation: UNICOM's primary purpose is to provide operational assistance to aircraft at non-towered airports, rather than to issue flight plan clearances.
UNICOM services are typically operated by radio personnel associated with fixed-base operators (FBOs), not by government-employed air traffic controllers.
Answer: True
Explanation: The operation of UNICOM services is commonly managed by personnel from fixed-base operators (FBOs) at the airport, distinguishing it from government-controlled air traffic control.
UNICOM operators do not possess the authority to issue instructions or clearances to pilots; their function is advisory.
Answer: True
Explanation: UNICOM operators are limited to providing advisories and lack the authority to issue binding instructions or clearances to pilots.
UNICOM advisories can provide pilots with valuable information regarding weather conditions, runway status, and other traffic in the vicinity.
Answer: True
