Having flown commercial jets in and out of Orange County Airport for many years, I can tell you that there IS NO MORE higher and sooner! That airport already requires ridiculous noise abatement procedures that already stretch most airplanes limitations! ...and if an airline sets off one of the many noise sensors on the departure path there, the airline will get fined! ...and usually pretty heavily at that!!
The procedure back when I was actively flying these OC trips was to run up full takeoff power on the end of the runway, then brake release. After this "catapult" style takeoff roll, the pilot then has to fairly aggressively rotate the nose (BUT DON'T SCRAPE THE TAIL!!!), and climb out at a very steep angle with V2 speed only to 800'! At that point the power gets reduced to a substantially less setting than normal climb power, and then you "tip toe" out past the shoreline before resuming a normal climb profile. All the while, when the power comes back that far, you have to again fairly aggressively pitch the nose over so you don't stall!! At the same time all this is going on, you also have to very precisely fly the lateral profile on the way out so as not to set off the noise monitors!!
That place can kiss my @$$!!
Ironically, one of the biggest opponents in the past to the noise from aircraft there, has a way bigger than life statue of him right there in the terminal... Mr. John Wayne himself!!
