As said earlier, COD's used to fly at night, but not anymore.
No nights for the COD for several reasons.
1. Airframe is old. Flying night hits reduces the amount of time that maint has to fix any gripes on the planes. We need the time to fix the planes. We only have 2 planes in each detachment so it's not like we can rotate them out that much. Normal ops is having 2 planes to make 2 hits everyday. No other squadron on the ship needs to have 100% availability EVERY DAY. The overnight maint period is a neccessity.
2. Keeping current is too difficult. Night currency req is one night trap every 7 days. We would have to fly night hits just for currency requirements regardless of the need. This would also wreck crew rest. The ship normally wants their first hits of the day pretty early in the day. After that hit, the crew would have to sit around for hours just waiting for dark to make the second hit "just for currency". There are only 6 pilots in a det and mix in SDO, etc and it becomes a very difficult managment issue for Ops.
3. No pax at night. As per OPNAV, we have to be off the ship 1 hour prior to sunset (waiverable to 30 min). Night pax overwater is permitted by OPNAV (not permitted for Helo's), it's the ship part that rules it out for the COD. This wasn't that much of a big deal because night was when they would fly the pony and parts. It's not too hard to fill a COD with all the mail and parts that the boat needs.
4. No real need. The COD does a good job of supplying the ship during the daytime hours, just because we can deliver stuff at night doesn't mean that it's the smartest thing to do.
5. I've got 145 night traps, I don't need/want any more.
