Timothy, you purchase a roll of sticky back cellophane (you know, the stuff that you protect kids schoolbooks with). Mark your chart and then stick a square of cellophane on top.

MQ.

Use a normal ink pen on the paper chart. No worries.

Slightly off topic but has anyone used the digitalised CAA charts?

Thanks

I use paper charts, nearly never draw on them so they are good for years (until they start cracking at the folds).
Frequencies are already supplied on them, so the only info I write on a piece of paper are the headings (if it is a long flight with twists and turns)and calculate the flight times between points while flying.
In Italy ATC always wants your estimated time over the VRPs so you are always calculating time to next point.

Ciao,

Agree with FFF, 6 min marks work well as a starter - in fact it does not really matter WHAT timing marks you use as long as they are at a sensible interval and all the same, 6 mins based on calculated groundspeed is just convenient and fills the bill, otherwise just use a "thumb" and whatever it works out at is your time marker.:ok: (personally I just draw on a track line and "thumb" distance for whatever I am doing - but that is NOT what I would teach a student).:ok:
