Narrative:

Taxiway A2 is not depicted on mke jepp chart 10-9 18 may 18. This is confusing since the [information page] for kmke states: 'after landing runway 25L -- be aware; taxiway bravo intersects taxiway alpha abeam A2'. After landing on 25L; ATC routinely issues the instructions; 'use taxiway alpha to bravo to the ramp.' they expect you to join taxiway bravo where it intersects with taxiway alpha abeam A2. When briefing this for arrival it was difficult to determine what the [company information page] was referring to; since A2 isn't on the jeppfd-pro chart.
