When a controller issues the instruction, "Standby," what does it mean?
Answer: The controller is busy and will call you back shortly.
When Air Traffic Control (ATC) issues the instruction "Standby," it means the controller is currently busy and unable to respond immediately to your transmission. It is an acknowledgment that they heard you, but you should wait for them to call you back when they are available. You should not transmit again until the controller contacts you.
What does the Class B airspace clearance requirement “Cleared into the Bravo” mean?
Answer: You are authorized to enter Class B airspace and must follow ATC instructions.
The phrase "Cleared into the Bravo" is a specific and mandatory clearance from Air Traffic Control (ATC) that authorizes an aircraft to enter Class B airspace. This clearance is crucial because pilots *must* receive explicit permission to enter Class B airspace. Once cleared, the pilot is expected to comply with all subsequent ATC instructions for safe operation within that complex airspace.
What is the meaning of a steady green light signal from the tower while you are on the ground?
Answer: Cleared to taxi.
A steady green light signal from the control tower to an aircraft on the ground means "Cleared to taxi." This signal is used when radio communication is unavailable or impractical. It authorizes the pilot to move the aircraft on the airport surface, typically to a runway or parking area, but not to take off.
Which airspace requires the use of a Mode C transponder?
Answer: Within 30 nautical miles of Class B primary airports.
A Mode C transponder is required within 30 nautical miles of Class B primary airports, often referred to as the "Mode C Veil." This requirement ensures that Air Traffic Control (ATC) can identify and track aircraft with altitude reporting capabilities in busy terminal areas. It applies to all aircraft operating from the surface up to 10,000 feet MSL within this specific airspace.
When should the phrase "Mayday" be used?
Answer: To communicate a grave and imminent danger requiring immediate assistance.
The phrase "Mayday" is an internationally recognized distress signal used to communicate a grave and imminent danger that requires immediate assistance. It signifies a life-threatening situation for the aircraft or its occupants, such as an engine failure, fire, or severe medical emergency. This call takes precedence over all other communications and should be repeated three times to ensure clarity.
