Question

.... how long will the chart be valid?

And: Is the chart valid on March 13 because at this date, the new AIRAC cylce is valid, or does Jeppesen bring out a new chart every thursday (or every two thursdays)?

Answer 1

As I recall, en-route IFR charts in the U.S. are reissued every 60 days.

Answer 2

The standard chart interval is 56 days.

Answer 3

If you have a Jeppesen enroute chart, it is valid until a replacement is issued.  If you have a subscription, look at page US-901 for a list of current charts.  If you don't have a subscription, look here: http://www.jeppesen.com/wlcs/gcn/Documen...

If that link doesn't work, you can go to http://www.jeppesen.com and then click on "Online Publications" and then "US Enroute / Area Chart Currency List".

If you are looking to use the chart for navigation, check the currency list first and then look for updates in the Chart NOTAMs, which can be found online here: http://www.jeppesen.com/wlcs/index.jsp?s...
