i guess i have already answered it with the reference
You have, but the reason I ask is because the link states 'sole manipulator of controls'.
Above what height the flight levels are to be used in India
a. 4,000 feet
b. 5,500 feet
I have read 5,000 feet. I have also read 5,500 feet. But then, isn't 4,000 the lowest transition altitude in India?
What is the correct answer?
