Narrative:

Taxied out on taxiway a from the terminal to runway 11. I was temporarily confused because there is a well-marked taxiway H near the departure end of runway 11 that does not appear on my pwm jepps 11-1. After confirming with the other pilot that we were indeed correct by staying on a; all the way to the end and that H did not appear on our jepps chart; we took off safely using the full length (from taxiway a entrance) of runway 11; as we had been cleared to do.
