If you are unable to contact a station on a designated frequency you should:
-
Try another appropriate frequency
-
Start transmitting blind
-
Land at the nearest suitable aerodrome
-
Transmit words twice
Correct Answer
A. Try another appropriate frequencyExplanation
If you are unable to contact a station on a designated frequency, the best course of action is to try another appropriate frequency.

Your reply to the message “REPORT FLIGHT CONDITIONS” should be:
-
VFR/IFR
-
SMOOTH/TURBULENT
-
NOT BAD/SO SO
-
VMC/IMC
Correct Answer
A. VMC/IMCExplanation
The correct answer is VMC/IMC. VMC stands for Visual Meteorological Conditions, which refers to weather conditions that allow for visual flight rules (VFR) operations, meaning the pilot can navigate and control the aircraft by visual references outside the cockpit. IMC stands for Instrument Meteorological Conditions, which refers to weather conditions that require instrument flight rules (IFR) operations, meaning the pilot must rely on instruments to navigate and control the aircraft. Therefore, the reply to "REPORT FLIGHT CONDITIONS" should indicate whether the conditions are suitable for VFR or IFR flight, hence VMC/IMC.Rate this question:

-
Poor
-
Medium to poor
-
Medium
-
Slippery
Correct Answer
A. PoorExplanation
The phrase "BRAKING CO-EFFICIENT 20" from ATC indicates that the braking action is poor. A braking coefficient of 20 suggests that the surface has low friction, making it difficult for vehicles to stop effectively. This could be due to various factors such as wet or icy conditions, loose gravel, or oil on the road. Drivers should exercise caution and expect longer stopping distances when encountering this braking coefficient.Rate this question:
