Mark,
Anything to excess would be a sin, excepting aircraft ownership. :)

When measuring dBs, is dBA or dBZ more relevant? dBZ is always highest IME.

I’m not a Conquest guy, what kind of cabin does it have at FL350?

I love flying... but I’m not spending 7 hours in any airplane!

Been to Maui twice. Big difference when you can get up and walk around the airplane. But... I still hated the flight and though I love Maui I go to Costa Rica about once a year and Maui once a decade. Three hours sure is nice.

Charles, for some reason that Mustang you’re referencing is a heck of a lot louder than mine, at least in cruise. I haven’t measured sound pressure during takeoff or climb, but my cruise levels are reasonably low.

Does an Aerostar with diesel engines count fer a T-prop?
I can dream....right?
Adding two 380hp EPS diesel engines in 3-4 years :cross:
280 KTAS on 32GPH of Jet-A...MY DREAM REMEMBER
Almost 2000 mile range so Iceland, Greenland, Baffin Islands, Alaska here I come.

Once I confirm diesels are a go then time for Paint, interior and avionics upgrades.

I hear GWX70 radar is sweet, Bendix King 130, not so much
Dual G600's (can you say RSVM!?) MY DREAM REMEMBER

My Unicorn might barely top $1M when all is done.

Ok, Pipe dream is somewhere between maybe and highly unlikely so realistic 3-4 year dream
is a TBM 700C.....saving so maybe TBM850 :drool:

That is the only one I have been in. Who knows with different sound meters may get slightly different results. I use my app more for relative differences than absolute Db numbers. Those levels are time limited, and hearing loss occurs over time. For the occasional passenger, those levels are nothing to worry about. For frequent flyers I would say a different story. even with My kids will have hundreds of hours flight time before they hit high school, so I think more about the cumulative risk. Even professional automobile drivers suffer a high rate of hearing loss. That is mostly bus and truck drivers but noise levels that we accept as normal can be damaging long term.

What altitude were you cruising at?

Adam, I know you have you flown a -10 Commander. I have had one to FL390 in the experimental category. There’s no struggling involved at 310!


You had a A/B to FL390?? Didn't even think they could get up there!


No it was a 980 or an 840 -10 as I recall. But I suspect a 690A/B would get right up there too.

Reminds me of meeting Bob Mays over at Van Nuys a few years ago to demonstrate an 840 to a prospective buyer. Everyone looked at the plane and seemed satisfied. Then they wanted to go flight check it for some validation of the deck angle as it was to be a special mission photo plane. Of course, the plane was full of fuel for some reason, there was a whole plane load of people, it was ISA+30 degrees out and, they wanted to go to FL 310. Did I mention this was a -5 powered plane with original engines which were 5000 hour never overhauled 35 year old engines? Anyway, Bob and I looked at each other, unsure as to what we were going to get and off we went. We climbed straight to FL310, it did book speeds, and when the protractor was laid down on the seat tracks, the deck angle was 1.5 degrees nose up. :thumbup:

With -10’s, the AI in cruise looks just like it does on the ground. Steve B can verify :peace:

That could be part of it. Only a short demo flight, so we stayed low, this was at FL220.

Yeah that could be although you did have power level pulled back going 198kias so that should offset some of the altitude driven wind noise.

I’ve tried a couple free noise meter apps in the house. Tried with a quiet house and a normal conversation. One registered 60dB in a quiet house while the other registered 35dB. Normal conversation had one of them 75 while the other was 55-60.

Given “normal” levels of those two environments I’d say the lower one was spot on and the higher one was reading significantly too high.

I’ll try the apparent more accurate one in the Mustang next time I fly.

You can get a great Cessna 441 (Conquest II) for 1.3 Million. If I had that much to throw at a plane that’s what I would be flying.

310 knots
2000 nm range
FL350
miserly fuel flow

What a machine

Every machine has its weaknesses, and the 441 is no different. It lacks adequate pressurization for FL350 (cabin altitude 11,000 ft) and FL350 is exactly what you want to use on long flights. It is somewhat lightly built (maybe that's everything out there relative to an MU2). It is punished by Cessna's inspection program.

But, even so, it is one heck of a machine, I think the best turboprop out there overall. Speed, range, looks, cabin, etc.

Can someone give me a ride in one? I really need it. I'm recovering from a dream crushing demo ride in a Citation SII and have started looking at 441s as my next airplane.

M-USHY flew through here the other day....I didn't see it in person but that paint scheme is simply stunning.

I would take dBA or dB(A) if bellow 100 dBA. dBA includes A-weighting that takes into account the relative loudness perceived by the human ear at different frequencies. This changes a little with the noise level. dBZ or dB(Z) doesn't include any weighting in the frequency range between 10Hz and 20kHz (with a 1.5 dB tolerance). Because A-weighting discounts noise levels at frequencies (roughly) below 1 kHz and above 8 kHz, dBZ generally shows higher readings, except for the noise with the pronounced spectral content between 1 kHz and 8 kHz where A-weighting gives even slight emphasis.

But, when comparing readings, they should be taken with the same weighting filter.

Also, low cost noise meters, as well as most smartphone applications, give only approximate values of real noise levels. Such devices probably can be used just for the comparison (measured by the same device), not for exact values.

Professional device are used with acoustic calibrators to calibrate the meter before measurement.

Anyway, stay below 85 dBA for prolonged periods.
