Re: ICAO Annexes for Aircraft Automation in Certification

Well, yes ICAO doesn't have any regulations as you described. I referred to to the CS-25 of EASA and it doesn't say anything much about the regulations (or soft laws) on automation of aircraft systems. But I find some info in the FAA CFR 14. 25 about some regulations governing automation. Is there a...

Hello guys,
If some got a chance to join an airline as an aircraft mechanic or aircraft maintenance planeer what will be the beat to choose? Any pros and cons in two careers. Salary will be same for both during first few years. Any kind of comments are highly appreciated.

You are correct Starlionblue! As A350 is not fitted with Trim tanks so it deploys flap to maintain the Center of Gravity within the limits.
