What does AOG mean?
 

In the airline I work for the term AOG is always used. 'AOG aircraft', AOG parts .. and so on.. It all has to do with either techproblems or maintenance. What does this AOG mean?

This has probably been discussed here a million times, but I really did my best in trying to search for it, but the forum will not allow searches for words containing only 3 letters and so on...

cheers

Aircraft On Ground. Puts high priority on a spares order, basically.

I had a roll of those stickers once. I tried it on my suitcase to ensure that it got there when I did.


it didn't help

Any part that keeps the aircraft from being released to service is considered AOG.
Since an aircraft sitting on the ground unserviceable does not generate money, the term AOG justifies higher purchase costs etc.

For normal on the shelf spares the company has the luxury to shop around.
When an aircraft goes AOG it is costing them money thus they will be prepared to go to greater lentgh to obtain the required part.

That is where loanparts come into view, companies will loan each other parts at high fares.
Availlabilty costs can start at 30% of the value of the part, even if only used for one flight!

The term also comes into play, and those stickers previously mentioned, when consigning spares and/or tooling etc.

Any IATA Airline is required by regulations to uplift these on their next flight, even if it is for a competitor and they don't really want to.

An Aircraft declared AOG [Aircraft on Ground].is in need of spares to get it airworthy again.Spares ordered on AOG basis is a <24hrs delivery but three times the cost from the nearest vendor.

AOG items get priority on carriage by other airlines too.

AOG spares
 

Pitot Tube. Just so you understand, AOG applies to military aircraft as well as civil. The civvies may loose money with their aircraft sitting on the ground but the military can't operate their aircraft with AOG spares outstanding either. The difference when AOG is the civvies loose money, the military saves it.

AOG
 

Aircraft On Ground due to technical problem(s) outside limits of the Minimum Equipment List/DDPG or pertaining to awaiting part(s) being shipped for the purpose. Sometimes, AOG situation is being raised by Flt Ops due to crew requirement.

I once worked for a company who had as a client a major Americain oil company. This oil company knows all there is to know about flying, and has produced a lengthy tome describing exactly how its air operations are to be carried out. It calls this book the Air Operations Guide. They abbreviate the title, and on the front cover, it says - AOG. It was confusing, to say the least, whenever AOG was mentioned.

The book is rubbish.

Act of God:O

and AOG is also the usuall excuse you get from crew control when they are in panic mode, total chaos, overloaded and forgot their own names...:}

In the '60s there were two RAF categories above AOG.
VOG. V Bomber on Ground.
LOG. Lightning on Ground.

Probably something similar today. All stops out.

A Lightning with tech problems? Surely not....

Actually, the highest priority in the 60's was "AOG Trans". This was awarded to Transport aircraft parts which, we were told in Transport Command, took priority over everyone elses bits and pieces.
