Interview Question Help!!
 

Q. Explain the NCP and explain the difference between the green and white announcements ?

Is this something to do with the auto pilot ?

Q. Why do we have different segments for take off ?

any help will be good thanks.

Is there some context to this?

Interview with whom, for what, and what do the questions relate to?

no idea what a NCP is, did you mean MCP?

You probably mean MCP (Mode Control Panel). The "green and white announcements" are the FMA (Flight Mode Annunciators) with respect to what has been selected on the MCP. The white annunciator means that the mode in question is armed and 'waiting' to be captured. The green annunciator means that the mode is captured.
