CTC Communication Protocols and Procedures 2 — Questions and Answers
Question 1: During a test countdown, the test conductor initiates a 'GO/NO-GO' poll. What is the correct response from a station that is ready to proceed?
- AFFIRM
- GO (Correct answer)
- READY
- CLEAR
Correct answer: GO
In a GO/NO-GO poll, each polled station responds with 'GO' to indicate readiness to proceed or 'NO-GO' to indicate they cannot support continuation of the countdown.
Question 2: What is the purpose of a Minimum Essential Communications List (MECL) for a test event?
- To list all frequencies and call signs assigned to the test event
- To identify the minimum communication links required to safely conduct the test (Correct answer)
- To document all communication failures recorded during previous test events
- To assign primary and backup communication roles to range personnel
Correct answer: To identify the minimum communication links required to safely conduct the test
The MECL defines the bare minimum communication links that must be operational for the test to proceed safely, serving as a go/no-go criterion for launch or test initiation.
Question 3: During a test event, the word 'HOLD' is transmitted on the countdown net. What must all range stations do?
- Cease all non-safety communications and await further instructions (Correct answer)
- Begin emergency shutdown procedures immediately
- Confirm their GO status and await the test conductor's direction
- Switch to backup frequencies and report their status
Correct answer: Cease all non-safety communications and await further instructions
A 'HOLD' command stops the countdown; all range stations must cease non-safety communications, maintain their positions, and await the test conductor's instructions.
Question 4: What does the proword 'ROGER' confirm in test range radio communications?
- The receiver has understood the message and will comply with instructions
- The receiver has received and understood the last transmission (Correct answer)
- The receiver acknowledges the message and is ready to transmit
- The receiver has copied the message and is logging it for the record
Correct answer: The receiver has received and understood the last transmission
'ROGER' means the receiver has received and understood the last transmission; unlike 'WILCO,' it does not imply the receiver will take action.
Question 5: What is a 'patch' in test range communications terminology?
- A software update applied to range command and control systems
- An electrical or electronic connection linking two separate communication systems or nets (Correct answer)
- A designated frequency reserved for emergency communications
- A written correction to a published communications plan
Correct answer: An electrical or electronic connection linking two separate communication systems or nets
A 'patch' is a connection that bridges two separate communication circuits or nets, allowing personnel on different systems to communicate directly during a test event.
Question 6: The phonetic alphabet representation for the letter 'K' in NATO/ICAO standard communications used on test ranges is:
- King
- Kilo (Correct answer)
- Key
- Kappa
Correct answer: Kilo
In the NATO/ICAO phonetic alphabet, 'K' is represented by 'Kilo,' ensuring clarity and preventing confusion with similar-sounding letters during radio communications.
Question 7: What is the standard protocol when a safety-critical communication system fails during an active test event?
- Continue the test while documenting the failure for post-event review
- Immediately initiate a hold or abort in accordance with the test plan's contingency procedures (Correct answer)
- Switch all communications to the primary net and continue the countdown
- Notify the range safety officer and await their direction before any action
Correct answer: Immediately initiate a hold or abort in accordance with the test plan's contingency procedures
Loss of a safety-critical communication link requires an immediate hold or abort per pre-planned contingency procedures, as the MECL threshold has been breached and the test cannot safely continue.
During a test countdown, the test conductor initiates a 'GO/NO-GO' poll.
