There is no App Ltg on the 09 end - and only puddle jumpers approach on 27.
09 has fairly standard runway lighting and from memory PAPI's on both sides. There is a VOR DME just to the right of the 09 Thr. - which is presumably calibrated to read 0 at the TDZ.
The airfield closes at 23:00L and re-opens at 07:00L (I think)
It's a fun place
But you can't hire anything from SXM, although it may be possible from the airfield on the french side.
