Pertaining to VMCG, what is true? A) It decreases with increasing temperature for the same pressure altitude B) It increases with decreasing ambient temperature for the same pressure altitude C) It decreases with increasing aircraft weight
Understand the Problem
The question is asking for the accurate statement regarding the behavior of VMCG under different conditions, which relates to aviation performance. It is necessary to understand how factors like temperature and aircraft weight affect VMCG.
Answer
It increases with decreasing ambient temperature for the same pressure altitude.
VMCG increases with decreasing ambient temperature for the same pressure altitude.
Answer for screen readers
VMCG increases with decreasing ambient temperature for the same pressure altitude.
More Information
VMCG is affected by the amount of thrust available, which is influenced by ambient temperature. Lower temperatures result in more engine thrust, thus increasing VMCG.
Tips
A common mistake is assuming VMCG decreases with a decrease in ambient temperature without considering the impact of engine thrust.
