Revisions

[coa787]

Hello. Does anyone know what it means when you have to do revisions on things such as your aviation charts, SID/STAR charts....etc? How would you revise them anyway? How important is it to make revisions, couldn't you just get new charts? Thanks in advance!

Revisions are new charts. Normally every two weeks you will get an envelope with all the plates that have changed in the last printing cycle. Then you have to go through your plates and throw out everything that has changed and replace it with the updates. Sometimes stuff gets tossed and not replaced (NDB approach a lot of times) and sometimes stuff gets added like new approaches or new airports.

It's mostly a pain but it has to be done. In theory you could just get a complete new set of plates every time, but that wouldn't be very cost effective.

Isn't every printing cycle about a month instead of two weeks?

They send out revisions every 2 weeks at my company.

I think when you order several thousand sets of charts at a time they're willing to print updates more often.

So, in order to revise your charts, you have to order them? What about when you're flying for an airline, does each airline pilot have their own set? Aren't the charts given to you by your company?

I go to the airport and down to the crew room.

Inside the crew room there are filing cabinets and each pilot has their own little hanging folder.

Every 2 weeks an envelope appears (for free) with the jepp revisions in it. Maybe 50-100 pages will be updated normally. So we go through our jepp binders, remove the old page, and put in the new page.

The jepps are customized for my airline, with special pages added which include specific information (operation frequencies, telephone numbers, what gates we park at, etc). 99.9% of the charts however are the exact same you'd get if you ordered them yourself from jeppesen.

The jepps charts (which fill 3 2" binders) are given to us by the company (for free) during training. Each pilot is required to have their own set, which makes up the majority of what we carry inside our cases.
