If they approve LIDO, hopefully never. Electronic Jepps would be a dream com true compared to LIDO. LIDO's are garbage IMO. Other airlines have tried them, and dropped them. All for the same reason. They just are not quality. Typos, missprints, important info either not on the chart or burried in the textuals. With jepps all the info you need is right in the chart. With lido, you HAVE to read the textual to make sure you are not missing anything important (because its not on the graphical).
