    $\begingroup$ I think this is used mostly by SAR or other military pilots when running grid work. $\endgroup$

    $\begingroup$ @RonBeyer: that makes sense, since the picture is about the search for the missing Malasia flight. So, normal commercial pilots would not do this? $\endgroup$

    $\begingroup$ @PierreB so what? You should always post it. ML knows how to (or at least give a (bad) approximation of a translation). Moreover, I am Greek, I can help if someone wants. iEfimerida stands for electronic newspaper. $\endgroup$

If you use a grease pencil, it rubs off easily from glass

So you can save paper, not have to look down or hunt for the info, it won't fall on the floor, and if it's written in the center of the windshield, both pilots can see it
