'd like to know if there is any way that I can find out at a glance when any of the aerodrome data charts have been updated so that I don't have to open each of them up.
In the AIP you can look at the upcoming AIRAC changes valid for 28 days from issue. Goto AIP, AIP Changes, AIRAC. Alternatively keep an eye each month on changes to AIC Green 58 via the AIC Cover Sheet.
