Using it as often as I do I'm constantly amazed at the convenience of YTZ for city residents.
If the TPA really wanted to put jets in there couldn't they build a new runway on a more SW heading out into the lake without touching the inner harbour areas?
A 7000 ft runway on a hdg of 06/24 out into the lake would sure attract a lot of larger jets and customers. It would also free up the needed ramp space.
Landings with higher tailwinds would have to become more common to reduce approaches over the city and keep the noise complaints down I suppose.
