Final answer:
Caution and advisory messages are usually inhibited during landing to minimize distractions to pilots. These messages are typically inhibited below a certain altitude, allowing pilots to focus on critical tasks.
Step-by-step explanation:
During landing, caution and advisory messages are usually inhibited when the aircraft is below a certain altitude, typically around 2500 feet above ground level. This is done to prevent unnecessary distractions to the pilots during critical phases of the flight.
By inhibiting caution and advisory messages during landing, the pilots can focus on crucial tasks such as maintaining the attitude, speed, and glide path of the aircraft. It also helps to minimize the risk of misinterpretation or distraction caused by non-relevant messages.
However, it is important to note that critical messages, such as those related to safety or system failures, are not inhibited and will still be displayed to the pilots regardless of the phase of flight.
