Are 707 And 727 Shaky In Climb?

Tue Jan 12, 2010 3:59 am

I was told, that even when they were new, 707s and 727s, was very shaky during their climb. Is this true?

I fly 707's and if there's turbulence, yes its shaky.

The absolute shakiest takeoff I have ever experienced was SQ1...a fully laden 747-400 (max. takeoff weight) out of SFO...the tail wags a lot on a fully loaded pretty good, for some reason  Wink

Ive flown on a good few 727's and can only say good about them.

OK so they're noisier than your 'modern jet' but in terms of smooth flying, I can't say I ever noticed them being more or less so that anything we fly in regularly today.

Sorry - what the heck is "shaky" mean. Vibration. Buffet? I'm confused by it.

The 727 can be very shaky up front on takeoff depending on how much weight is on the nose
gear and the airplane. My first flight flying the airplane I was surprised how bumpy it was, now's it's just normal.

Climb out is fine, unless like said above, there is some turbulence. Then most of the time there is a side to side movement. It feels cool.

I'm just wondering: How a 727 vs. a 737-800 would be any shakier given the same circumstances?

Shaky? Do you mean a pronounced yaw moment, or what? I have flown hundreds of flights, in both types, and I have never experienced that sort of thing. In fact, there was no better ride in turbulence than in the 707 and the 727.

If you find the 707/727 shaky,Check out the takeoff of this A346...
Keep flying, because the sky is no limit!

Shakey?

Well, it depends.

Circa 1979, after takeoff from Madras India, passing through about 6000 feet....B707-320B (advanced cowl).
Extreme turbulence.
I can't read the instruments..
The First Officer can't read the instruments, either....and he's flying the airplane.
Like a cork in the ocean...lucky to keep the blue side up.
The First Officer does well, keeping the proper attitude on the ADI.
I look out at the left wing...and note it is flexing waaaay up and down, and the engine pods are doing the typical pod-nod, that you notice in turbulence.

I recall thinking...good thing Boeing bolted the wings on REALLY tight in Seattle, long ago.

Then, just as suddenly as it started, the turbulence stopped.

Another day...another dollar.
And, keep the shoulder harness firmly fastened after takeoff...as you never know what might be in store at lower levels.

I wouldn't call a B727 shaky on climb out, certainly no more so that a B73G or 8 or A320, under normal circumstances. Now on the runway, that's a very different matter, particularly on a max performance take off, when the pilot has the engines to full power with the breaks jammed on. Now that's SHAKY! Every thing shakes, the walls, the seats, the pax, the overheads and if you look out the window at that amazing wing with all the slats, flaps etc deployed, they all shake too! Now combine that with a short field take off where he gets it off the ground asap, pulls in the gear and accelerates in ground effect, now that's shaky too.

Ha, yeah, if we are talking about the "shaky" where you are at takeoff thrust with brakes applied, try sitting in the last row of a 777. I was nearly bounced out of my seat!

You're talking about a normal departure from SNA, then, right?  Smile

One of the things I miss about my previous-1 job is taking off out of SNA. It was always amusing to hear how different pilots would explain what was going to happen, for the sake of the infrequent flyer pax. Once I sat next to some poor guy who was an uneasy flyer at best, and he nearly had a coronary. I spent a good 15 minutes explaining how the plane wasn't really going to shake itself to bits.

Interesting question, would a 707 or 727 be OK with SNA's puny little runway? Would they be weight limited at all? (Let's agree to ignore the noise factor, the thought of a JT3C-equipped 707 thrashing Newport Beach is pleasing but it would use up the noise quota for a year...)

Weight limited most certainly.
Example.
B707-320, JT4A-17 engines.
MTOW, 317,000 pounds, standard day, sea level, no wind, requires....11,300 feet of runway.
SNA would be just a tad short.

Actually POM in the 60s.  Smile

Slightly under 7,000' runway, sea level, but very hot 38C+, light to no wind, B721 at near if not at MTOW (every seat full) for a 1500 nm sector non stop to SYD. Talk about shake! And it kept up while he kept it in ground effect, once established in climb, very smooth.

Shaky? Try the back row of a stretch 8 or 753.
