Listening to the approach tapes at LiveATC.net, it sounds like BISCAYNE 293 originally was going to plan on the RNAV 28. Approach says he just talked to Navy Jax tower and that both runways look pretty bad, socked in with moderate to heavy precipitation both east and west of the airport. Approach says Navy Jax tower is closed so he can have either runway he (LL293) wants.
Approach asks if LL293 wants to try runway 10, says it might be best. LL293 says yeah, go ahead, let's do it.
They get vectors for the RNAV Runway 10 and are told to contact Navy Jax GCA on 127.7.
