The John Wayne Airport has recently implemented a new noise sensitive departure procedure. Here's how it works.

1. Planes spool engines up, and set takeoff thrust (usually maximum, no derate), as usual
2. Takeoff and climb at a steeper than usual pitch, as usual
3. Power is cutback at 800 feet, as usual
4. Pitch of the nose is lowered if necessary (which is most of the time), as usual
5. Proceed to BIKKL, turn left to HEFAY. At HEFAY, turn right PAPAU. At PAPAU, turn left LRREN, and continue HTCHR and proceed on the STAYY1.
6. At 3000 feet, restore thrust and clean up (flaps up). Flaps are kept down until 3000 feet when thrust is restored.

It's basically a left, right, left takeoff opposed to the left turn takeoff.

This is a new NextGen RNAV takeoff procedure. It is the first one in the country, and is still the only one. This SID is currently only used by Southwest. It will eventually expand to other airlines, but while Southwest does this CaptainOnly departure that you need to be qualified to fly, the other airlines fly the standard NADP1 and NADP2 departures.

NADP1: Climb steep
Cutback power at 800 feet
Turn left and follow the SID (no left, right, left)
Restore thrust and clean up at 3000 feet

NADP2: Climb at lower initial pitch
Set climb thrust at 1000 feet
Turn left and follow SID (no left, right, left)
Restore thrust at either the coast or 3000 feet
