AVOP Airside Zones and Communications 2 — Questions and Answers
Question 1: What is the difference between ground control and tower frequencies?
- No difference
- Ground handles taxiway movements, tower controls runway operations (Correct answer)
- Ground is aircraft only
- Tower handles everything
Correct answer: Ground handles taxiway movements, tower controls runway operations
Ground control manages taxiway traffic; tower manages runway operations.
Ground control handles all taxiway and non-runway movement area traffic. Tower manages runway operations. Vehicle operators typically use ground control but may be handed off to tower for runway crossings.
Question 2: What communication requirements apply in the non-movement area?
- ATC clearance required
- ATC not required but must follow ramp control procedures (Correct answer)
- No communication needed
- Text messaging only
Correct answer: ATC not required but must follow ramp control procedures
The non-movement area does not require ATC but does require following ramp control procedures.
ATC communication is not required in the non-movement area. However, operators must follow ramp control or management procedures and company protocols. When transitioning to the movement area, ATC communication must be established before crossing the boundary.
Question 3: What is ATIS?
- Automatic Toll System
- Automatic Terminal Information Service with weather and operational info (Correct answer)
- Air Traffic Intelligence
- Airport Intercom
Correct answer: Automatic Terminal Information Service with weather and operational info
ATIS provides continuously updated weather, active runways, and NOTAMs.
ATIS is a continuous broadcast of current weather, active runways, NOTAMs, and operational information. Each update has a letter identifier. Vehicle operators should monitor ATIS for current conditions and include the letter when contacting ATC.
Question 4: Which zone requires continuous two-way radio communication with ATC?
- Non-movement area
- Sterile area
- Movement area (Correct answer)
- Public area
Correct answer: Movement area
The movement area requires continuous radio communication.
The movement area requires continuous two-way radio communication. Operators must monitor the frequency, respond to calls, read back clearances, and report position when requested. Radio failure is an emergency requiring immediate stop and visual signal monitoring.
Question 5: What is the proper procedure for switching from ground to tower frequency?
- Switch immediately
- Acknowledge, read back frequency, switch, and contact new controller (Correct answer)
- Wait 5 minutes
- Ask three times
Correct answer: Acknowledge, read back frequency, switch, and contact new controller
Acknowledge the handoff, read back the frequency, switch, then make initial contact.
(1) Receive instruction, (2) read back the new frequency, (3) switch to the frequency, (4) make initial contact with call sign and position. If you miss the frequency, ask for it to be repeated—do not guess.
Question 6: What is the significance of the movement/non-movement boundary for communications?
- Just a visual reference
- Marks where ATC communication becomes mandatory (Correct answer)
- Where radios must be turned off
- Only relevant for aircraft
Correct answer: Marks where ATC communication becomes mandatory
The boundary is where ATC communication becomes mandatory for vehicle operations.
Before crossing into the movement area, a vehicle operator must have a functioning radio, be on the correct frequency, and have obtained ATC clearance. Crossing without communication is equivalent to entering a controlled area without permission.
