OK, so first off, I am always fascinated with jet service information as it relates to the EIS airport that gets posted here.

For the folks on here that know your stuff can you indulge me?

1 - TERPS and GPS/RNP etc., et all....why is it that the 900 Hawker (V-GAL in particular) doesn't need to use these types of approaches...because it's private?

2 - Is EIS lighted at night, can it be, does it need to be?

3 - Aren't night landings at EIS subject to fines/fees?

4 - Are jet pilots (or all pilots) landing at night at EIS required to maintain any special certification for this?

5 - Though I am not a pilot, I'm assuming landing at night at EIS is Instrument approach...it looks like there are all sorts of instrument approach varieties...what is used for EIS?

Thanks in advance.
