Helicopters are extra special with all the gearboxes, servos and even rotor blades having life limits between 1500 hrs and 2500 hrs for most components. Back in the 90s it would cost us $250,000 to overhaul a turbomecca engine that would have a TBO of 2500 hours, then you still had the transmission, drive shafts, gearboxes, rotor blades and so on. I believe our TBO cost was close to $500 an hour for a 7pax+pilot Astar.
I had a friend who was a copter pilot and he described a helicopter as "several thousand unrelated parts flying together in close formation." LOL

Don't know much about Orange County and the area around John Wayne Airport (especially west thereof), do ya?

John Wayne has the wildest ride on its noise abatement procedure. Here's a video that shows the aggressive angle on the initial climb to altitude, then a reduction of power at a level intermediate altitude until reaching the coastline. It's all about containing the noise footprint.

The best part is from 7:30-10:00. As they reach the coastline, you'll hear them power up and, as the speed increases, the flaps retract for a more normal climb.

When done 'properly', you can give the passengers a reduced G experience at the intermediate level off. It can be fun or nauseating....depending on your preference.

When done properly the passengers don't notice a thing, nor do they need to. It's a tight but by no means "abnormal" procedure.

We used to slip the LJ-60...even in flight demos. It was quite a hoot.

When done properly, you work for a company that has a fleet that is quiet enough not to have to all of that stuff. Yes, the United 737 fleet no longer has to do all of those shennanigans!!! I am pretty sure the Airbus fleet still does. Not sure if SWA still has to do that stuff. THe craziest thing is we bring -800s in there now and we use every inch of that runway. I feel like we are doing a total buzz job when taking off out of there in an -800.

You're not looking for logic or common sense in this business are you?

It's amazing how many pilots gravitate to boating and visa versa and how many do both.

As a retired airline guy, the posts by Baker and FlyWright at pretty accurate.

I've declared an emergency many times, and min fuel many times over the year and it's never been an issue, both in the airline business and general aviation. The company reports were dirt simple, and what ever agency wanted a report, was pretty simple, too. Like the fire department wanted a report on why they had to roll the trucks, and often it would be filled out before I signed it.

Not once was there any issue. Now, for me, it there's ANY doubt that the flight can continue safely for any reason, I'll declare. I can always cancel the emergency.

I did that Sydney run out of San Francisco many times. One does have to be careful with fuel on that one because there's not a lot of alternates once you get close.... actually none. So careful fuel monitoring was not just a nice idea, it was mandatory. Fortunately, for me, never had an issue and found the Aussies were great to work with.

Now, in the mentioned flight above, I'd be nervous with flying that light twin from LA to Sydney. They call that an ETOPS operation, "Extended Twin engine Operation Over Sea". It should be Engines Turn Or People Swim.

I much prefer four engines where an engine failure is a minor inconvenience not a catastrophic emergency.

Seevee, apart from the A380 and some remaining B747s we see mostly twin engine longhaul planes coming here. Lauda was an early adopter,with a B767(later777) service between Sydney and Vienna. Fastest service to Europe,quick refuel stop, and even faster when Lauda himself was flying the plane.

Bruce,

Ya, times are changing. The old trusty 747 is pretty much retired. She was a great plane, and pretty efficient. Never had to off load pax or cargo to make it and no ETOPS rules. Miss that plane......

Qantas still actively flies them while gradually replacing them with 787s. Qantas missed the B777 generation altogether. They now fly the 787 from Perth to London nonstop and I think are planning Sydney - New York, with them or maybe an A350. After a near death financial experience Qantas is again generating strong profits, and dividends.
I can`t/won`t pay for Qantas longhaul,now it`s a 787 or A350 with an Asian carrier. The new planes are good but upstairs on a 747 was so quiet...

Snip
In 34 years of airline flying I've declared min fuel one time. Taking off out of PHX (Phoenix) during the summer when the OAT restricted Takeoff weight that limited the amount of fuel we could carry. Aircraft was a Airbus 321 and we knew before takeoff that we would be min fuel. There are no forms to fill out and ATC does not give you priority but the designation of min fuel makes ATC aware that your fuel situation does not allow off course routing or holding. Emergency fuel is a different issue and different rules are followed. I'm glad I never had to go down that path.

Good to see you back in these waters, Timjet. I hope this means you're buying another boat.

Thanks for the kind words Al. We have no plans for a boat. My wife is not a boater and she was very kind to follow me on our 7 years of power boat ownership. We have a motor home and have been using it pretty much like we used the boat - a lot. She loves it. For me I wouldn't hesitate to consider a boat again but as they say, happy wife happy life.

Socialist? Don't like it there? Don't live there just like you can choose not to live near an airport. If California is such a bad place to live, why is is that California continues, as it has for decades, experienced a net in migration? I wouldn't choose to live there but lots of folks seem to like it, more and more every day.
