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...

Re: ICAO Annexes for Aircraft Automation in Certification

Thanks for replying me and your guidance helped me a lot. I will look in to ICAO Annex 8. I want to write about automation regulation under ICAO, FAA and EASA.

ICAO Annexes for Aircraft Automation in Certification

Hello all, I'm in a big rush for finding some links to collect some information for this question "Which ICAO Annexes are regulating aircraft system automation during the certification of an Aircraft?" If you could show your helping hand with some links or some data, that will be a huge he...

Re: Aircraft mechanic vs Aircraft maintenance planner

Get your A&P and a business degree which will enable you to become a planner. Twist wrenches for a while, even if its on little airplanes. Become an expert at job cards, AD compliance and all the maintenance manuals. Having that skill set will help open doors in planning should you wish to purs...

Re: Aircraft mechanic vs Aircraft maintenance planner

Is that the main difference?

Aircraft mechanic vs Aircraft maintenance planner

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.

Re: Tackling the Commercial Pilot

Big thanks for mmo and Woodreau!. I figured out for what should I pay attention to.

Re: Tackling the Commercial Pilot

Thanks woodreau. This will help me a lot. What kind of technical questions will be useful to get familiarize with?

Tackling the Commercial Pilot

Hello avgeeks,
Hope we got lot of experienced commercial pilots on board
My question is what will be the most important and challenging questions that will be raised in an interview for a commercial pilot? Any kind of explanations are highly appreciated!

Re: Who should leave the aircraft first during a hijack?

Re: Loose, Leaking or Missing Engine Oil Filler Cap

Re: Who should leave the aircraft first during a hijack?

Well.... you haven't said whether the hijackers were discovered before departure. that wouldn't make them very good hijackers would it. I imagine hijackers would be very compliant, courteous, nice, and accommodating until they didn't need to be. Anyways, based on your prior postings, I believe you ...

What is new in CFM LEAP-1A

Hello guys, Recently I got a chance to work with few brand new A320neo and A321neo aircraft and they were fitted with CFM LEAP-1A engines. I noticed some differences in the LEAP engine when compared to other A320 family engines(mainly CFM 56-5B and V2500). What I noticed is, 1. It has a flag to indi...

Re: A350 Flap? extension at cruise during turbulence

I was not arguing with you Starlionblue, I'm not that much genius
Thanks for the crystal clear explanation and I thought that Trim tanks are solely to cater the CG shifts and never thought about improving efficiency.

Re: A350 Flap? extension at cruise during turbulence

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. I think it is some thing like Aileron droop that happens during the flap extension and this small droop is not indicated in the displays. IIRC aileron droop du...

Re: Loose, Leaking or Missing Engine Oil Filler Cap

This should give you an idea. http://flytristar.tripod.com/article/art10.html It helped a lot mmo. Gave me an idea how worse it can be! Every time I've seen this, and I've seen more times than I should of, it has resulted in an air turn back. Apparently, the oil does not begin to leak out the fille...

Loose, Leaking or Missing Engine Oil Filler Cap

Hello Avgeeks, I just wanted to know what will happen if some one install the oil filler cap in a wrong manner or with a damaged O ring( that allows fluid leakage ) or in the worst case, if the person forgets to install the cap and then the aircraft is released :shock: . For sure oil will leak out d...

Re: Maintenance Bus in A320

I’m sure the AMM has a basic description somewhere, but I would look in the wiring diagram and see who (system-wise) are the users.

Do you guys have any document related to this?

Maintenance Bus in A320

Hello avgeeks, I got a question about the Maintenance mode on Airbus aircraft. We turn it on if we no longer need the power for cockpit instruments and other main functions. If any cleaning process is carried out in the cabin by cleaners, we turn Maintenance mode ON for them to keep the cabin lights...

Engine driven fuel pumps

Hello avgeeks, I got a problem when going through some articles about aircraft fuel systems and how fuel is fed to the engine. Already I know that there are booster pumps in wing fuel tanks and center tanks to supply fuel to the engine driven fuel pump with a head pressure. My question is what will ...

Re: About APU start up / Shut down

The APU is fed from the trim tank if there is fuel in it by using the aft APU fuel pump, and from the wing tanks otherwise using the forward APU fuel pump. If the standpipe should be empty for some reason (well, not so much empty filled with air) you can't start the APU as the fuel won't be sucked ...

Re: About APU start up / Shut down

We always start the left engine first on the 330. Operator specific? yes you are correct Starlionblue. It should be the other way around . A320 right engine and A330 left engine. On the 777 we start both at the same time on the -200 and -300; the -300ER's huge engines demand too much air so it's on...

In our airport APU is started before the push-back and after landing the aircraft. We disconnect the GPU before commencing the push-back and aircraft PACS are supplied by the APU bleed.
