MAYDAY spoken 3x is a distress signal used in emergency situations, particularly in maritime and aviation contexts. It indicates that the person or vessel is in immediate danger and requires immediate assistance. The repetition of the word "MAYDAY" three times is done to ensure that the distress signal is clearly understood and to grab the attention of anyone monitoring the communication. This signal is universally recognized and should only be used in genuine emergencies.Rate this question:

When operations are different time zone, how should the date and the time of the day be expressed if it is 4:20pm(EST) of the 16th day of the month?
- A.
161620E
- B.

When the condition concerning the safety of the aircraft/vehicle/person on-board but does not require immediate assistance is?
- A.
Blind Transmission
- B.
Urgency
- C.
Distress
- D.
All other aeronautical message
Correct Answer
B. UrgencyExplanation
The correct answer is "Urgency." Urgency refers to a condition concerning the safety of the aircraft/vehicle/person on-board that does not require immediate assistance. It signifies a situation that may develop into a distress condition if no action is taken. Unlike distress, urgency does not involve an immediate threat to life or property, but it still requires prompt attention to prevent the situation from worsening. Blind transmission, distress, and all other aeronautical messages are not the correct answers as they do not accurately describe a condition that requires immediate assistance or the safety of the aircraft/vehicle/person on-board.Rate this question:

- B.
At the Office
- C.
At the aircraft
- D.
Carried along by radio operator at all times
Correct Answer
D. Carried along by radio operator at all timesExplanation
An operator certificate should be carried along by the radio operator at all times. This is because the certificate is an important document that verifies the operator's qualifications and authorization to operate the radio equipment. By carrying it at all times, the operator can easily present it when required, such as during inspections or when requested by authorities. Placing it at the hangar, office, or aircraft may not be sufficient as it may not be readily accessible when needed.Rate this question:

What is the normally used for ATIS broadcasts?
- A.
Discrete VHF frequency and/or VOR
- B.
DME Voice Channel
- C.
NDB frequencies
- D.
VOR Channel
Correct Answer
A. Discrete VHF frequency and/or VORExplanation
ATIS broadcasts are typically transmitted on a discrete VHF frequency and/or VOR. VHF frequencies are commonly used for communication between aircraft and air traffic control, making them suitable for broadcasting ATIS information. VOR (VHF Omnidirectional Range) is a navigational aid that provides aircraft with information about their position and heading. Since VOR stations are already equipped with transmitters, they can also be used to transmit ATIS broadcasts. Therefore, both discrete VHF frequencies and VOR can be used for ATIS broadcasts.Rate this question:

BLIND TRANSMISSION means?
- A.
Transmission of Information relating to air navigation that is not addressed to a specific station
- B.
Transmission from one station in another station in circumstances where two-way communication cannot be established but it is believed that the called station is able to receive the information
- C.
A transmission of messages relating to in-route weather information which may affect the safety of aircraft stations that is not addressed to a specific station
- D.
Transmission where no reply is required from the receiving station
Correct Answer
B. Transmission from one station in another station in circumstances where two-way communication cannot be established but it is believed that the called station is able to receive the informationExplanation
BLIND TRANSMISSION refers to the act of transmitting information from one station to another in situations where two-way communication cannot be established. This means that the transmitting station believes that the receiving station is capable of receiving the information, even though there is no confirmation or reply from the receiving station. It is a way of sending important messages when direct communication is not possible.Rate this question:

- A.
Roger
- B.
Verify
- C.
Wilco
- D.
Affirmative
Correct Answer
C. WilcoExplanation
The phrase "Wilco" is the correct answer because it is a combination of the words "will" and "comply." In aviation and military communication, "Wilco" is used as an acknowledgment to indicate that a message has been received, understood, and will be complied with. It is a concise and efficient way to convey this information. "Roger" is used to indicate that a message has been received and understood, but it does not imply that the message will be complied with. "Verify" is used to request confirmation or clarification, and "Affirmative" is used to indicate agreement or a positive response, but neither of these phrases conveys the specific meaning of "Your last message received, understood and will be complied with."Rate this question:
