Final answer:
The use of speed brakes can be inhibited in certain landing configurations, such as when landing with a tailwind or on a contaminated runway.
Step-by-step explanation:
In landing configuration, the speed brake is an important tool for controlling the aircraft's speed during descent and approach. However, there are certain scenarios where speed brake extension can be inhibited or restricted.
One example is when the aircraft is landing with a tailwind. In this situation, the use of speed brakes can result in instability and reduced control, so they may be inhibited to maintain the stability of the aircraft.
Another scenario is when the runway is contaminated with ice or snow. In such conditions, the use of speed brakes can lead to a loss of control due to reduced friction between the landing gear and the runway. Therefore, speed brake extension may be inhibited to ensure safer landing.
