Chart Or Publication; Human Factors
Upon landing my IPad jepp FD Pro defaults to the AMM (Aircraft Moving Map) taxi chart. It appears on rollout and pops up too small and taxiway markings are not readable and not even portrayed until you blow up the map. So if I am on a rollout and get a clearance to clear at a certain taxiway; I might not be able to find it especially at night in the rain. Most of the time I do not have a free hand to let go of the tiller and throttles and reach over to blow the chart up so that I could see it. I have tried turning it off to no avail. It is set as a default and will not change. I am finding this to be a dangerous distraction on the landing roll and runway exit.
B737 Captain reported iPad Jeppesen FD Pro taxi chart defaults to small scale; difficult to read; moving map on landing resulting in a dangerous situation.
