Excellent catch!! SNA is my local airport that gets jets ,as well as CNO. N42FL comes in to SNA very often according to live tracking on flightaware ,and I've caught it taking off back in December (which was also my first time catching a GIII). But what I hate the most is those QS3 hush kits because the ejector (trash cans) are larger then the ones on the QTA hush kit ,which means the QS3s absorb more sound then the QTAs ,which means their quieter. But what I wish the most is if they just don't have the ejector ,but just have the mixer. With just a mixer and no trash can ,It will be louder for sure as the sound isn't absorbed by the acoustic liner in the ejector. So for example ,a 727 ,732 ,DC-9 ,etc have just a mixer for the hush kit which really doesn't quiet it down that much ,probably about 2 decibels quieter then the original Stage II noise levels from the engines. But if they were to add the ejector as well (which hopefully wont happen to them in the future) ,they will become A lot more quieter ,Id say probably about 5 decibels quieter then just a mixer (which is bad). But the good news is ,is that on March 9th ,the ZeroG 727 will be at long beach ,and will take off at around 11:30. I'm going to make it out there to catch that loud beast. Hopefully the pilot doesn't do a reduced power take off though. I hope I taught you something new about the fact that the ejectors are bad news ,and will kill all the sound completely. Ill take just the mixers any day over hush kits that have the ejector. But still ,un hushed Is the best option for all of us.
Duderocks5539 Yeah I didn’t know much about the different types of hushkits such as the ejectors, but the noise restrictions really do take the life out of aviation. That’s awesome that ZeroG is visiting Long Beach. Sadly I think I will be out of town on 3/9. Always cool to see 727’s active.
+LoveJT8D That sucks you’ll be out of town when that good ol 3 holer will be at KLGB. But yeah like I was saying ,all hush kits are a mixer ,but if you add that ejector or trash can ,it will be even quieter since it absorbs the sound. It will honestly sound like a typical high bypass engine which sucks ass. But if the GIIs and GIIIs had Stage III hush kits that are just a 10 lobe mixer ,they would only be about 2 decibels quieter then un hushed. But as soon as you add that trash can ,it becomes 5-6 decibels quieter then noise levels with just a mixer. And what’s also unfortunate is the two hush kits made for the GII and GIIIs both have the ejectors ,but the ones on the QTA are smaller and don’t absorb as much sound. If they only just were a mixer they would be definitely louder ,unlike the mixer and ejector combined.
Duderocks5539 The good thing is those hush kits can never suppress the whine coming from the front of the engines. One of the coolest things about the SPEY.
+LoveJT8D True. The whine definitely seems quieter with the hush kits though ,and you don’t hear the roar while it’s coming towards you like the sound of a fighter jet approaching you on afterburner on takeoff if you know what I mean.
+mymousemalinu Exactly. Blame it on the bullshit FAA for requiring Stage II aircraft to be Stage III hushed. The thing I hate most are the QS3 hush kits (Which this GIII has equipped with) ,they really quiet the Speys alot more then the QTA hush kits. I really just wish the hush kits didn't have that ugly ejector (aka as trash can) which absorbs the sound. With just a mixer ,It will still be pretty damn loud. I'm hoping aircraft like the 727 ,732 and DC-9 don't get fitted with ejectors in the future ,even though they already have Stage III mixers in the tail pipes of the JT8D-1 through -17s. But If they were to add an ejector in as well ,It will sound like a damn high bypass engine now since the sound is absorbed. But with just a mixer ,It only will eliminate about 85% of the crackle you hear (which indicates a supersonic exhaust) ,but still a little of the crackle will bleed through ,but its not going to be full on crackle like with out the mixer. But if you add the ejector while keeping the existing mixer. It wont have any crackle anymore ,and the rumble will be quieted a shit ton now. I just wish the hush kits for the GII and GIIIs were just the stranded 10 lobe mixer without the ugly ass ejector (trash can) which will take the sound away completely ,unlike a little bit with just a mixer.
mytmousemalibu Same here! Was really surprised to see a GIII in general at SNA. Much more noise restrictive there than VNY. Seems like GIIIs are almost nonexistent at VNY now. Even though hushkits suck, I still see it as some borrowed time for these classic birds.
@@Duderocks5539 Yup, we have a G-III on the ramp next to ours with the QTA kits. My repair station works on mostly the Hawker 4000, it has PW-308A's which make some nice noise & smoke! I wish I could yank out the mixer and put a straight nozzle in it! I used to work for Bombardier/Learjet in experimental flight test. For the 50 year anniversary we had customers fly in with most of the older Learjets for the show. Clay Lacy Aviation brought a minty clean Lear 23 that made some low passes over the facility. It was music to my ears when they firewall'd the throttles on the little CJ610's!
+mytmousemalibu I’m pretty sure the engines in the 4000 are mid bypass turbofans, but you are correct on the mixer ,it’s bolted to the core section of the engine. Mid bypass turbofans are the most common powerplant on modern business jets. And those little CJ610 turbojets are very very loud ,it’s hard to believe an engine only 45 inches long and 17 inches in diameter makes all that noise. But trying to hush a pure turbojet engine isn’t effective really as there isn’t any bypass air to mix. And plus back in October 2017 I saw an un hushed Lear 24 takeoff from KLGB which tells me the FAA allows a handful of Stage II business jets to fly without Stage III hush kits.
I'm VERY surprised that a noisy bird like a Gulfstream III would be allowed to land or takeoff from Orange County Airport, even with hush kits installed on the engines. I thought their noise abatement's were too strict for even that. Shows you how little I know...
R. L. Smith I thought the same as you actually. Even about 4-5 years ago, There were G3’s regularly flying into Van Nuys. As I mentioned in a previous comment those old Gulfstreams pretty much seem nonexistent at Van Nuys and Burbank for that matter. I think SNA is much stricter on noise then other SoCal airports that I know. I definitely did a double take when I heard those SPEY engines powering up.
+R. L. Smith I always thought that too. Until one day I came across a video by IFLYSNA94 of him plane spotting at John Wayne in 2014 ,and he caught an un hushed GIII taking off ,which I believe was N18ZL. That surprises me ,since John Wayne does infact have way more noise restrictions then VNY and BUR and basically any other SoCal airport. I also always thought SNA banned Stage II aircraft from operations there since the 1980s or so. I thought they only just allowed Stage III ,and obviously now Stage IV as well. But he filmed that video before the Stage II business jet Stage III hush kit requirement deadline was that had to be done by the end of 2015 ,(Stage II airliners had to be Stage III hushed by the end of 1999) So I’m pretty sure after 2015 ,the airports will only allow Stage II aircraft that are Stage III hushed like the GIIs and GIIIs ,etc. The only Stage II business jets and airliners that will be able to not have Stage III hush kits installed are civilian operated ones that got special permission to do so after the late 2015 deadline ,or if its military/government operated.
@@LoveJT8D ah thats a bit disappointing haha. Ive heard speys are notoriously loud. maybe only when they're unhushkitted. have you heard a unhushed 737-200 takeoff?
The spey and the JT8D-1 sound AWESOME outside!
They absolutely do! Lots of thunder and smoke.
The only aircraft in the Sky headed to Hawaii from SNA - Love it !!
Scott Campbell That’s cool! SNA is definitely lucky to have classics like these still operating out of there.
Music to my ears. Great footage. THUMBS UP :)
Glad you enjoyed. Those SPEY engines really do sing :)

Too bad she's required to wear hushkits. I want to hear the Spey's thundering away!

Are these still fairly noisey even with the hushkits, is the noise equal to a 737-200?
I'd say not as much bass in the sound comparied to a 732 but still louder than most modern biz jets.

That Virgin America plane is actually Alaska Airlines now. It just hasn't been painted yet.
