737 Take off at 17 center

[johnathan]

Here is a shot from the other day. 737 taking off at DFW. I tried to apply some of the tips I have received here on pp. Funny you can see the pilot in the cockpit and several passengers through the windows.

Clipping a wee bit of the horizontal stab but otherwise, stunner...

Well Done!

[johnathan]

Thanks Jay.

[SheRidesABeemer]

love the vapor under the plane!

[johnathan]

Gail Thanks for your comment.Wish I could take credit for it but the camera does a great job of capturing it.They really put out a lot of hot air ha ha.
Funny thing is I love the smell of that jet-A burning.Takes me back to being 19years old and my first time on the ramp.Of corse that was three decades ago.

Nice shot thanks for sharing.

[gonças]

Spectacular!!!

[Field of 33]

Very nice shot. The best comment I can make is that it looks real, it doesn't looked PPed at all. Very well done!

Would you mind sharing your EXIF with us?

[PhotosGuy]

I like that SO much better than just seeing one in the sky!

[NicolasRubio]

I'd level it a bit more, like this:

PS: Try to get the missing piece of the horizontal stabilizer from another photo!

Thanks ya know I didn't know that I had cropped off the elevator I will get to work on that.

Namec Thanks for your comment.Glad you like it !

For those that notice the difference I should have saved the psd of the original then the last one would have bee the same but a different crop. Cheers ;)

Those shots look great. If you don't mind me asking, where at DFW are you shooting from? I'm very familiar with the area, very.

Thanks for the complement. It is amazing what you can get with a 400 mm lens and cropping. Cheers

Johnathan,
Really nice shot,
I'm glad that you called it an elevator, rather than a horizontal stabilizer! (Sorry Jay!) I'm an old fashioned type that was taught that it was rudder, elevators and ailerons.

BTW I agree with PhotosGuy re the background, it does make a difference.

Thank you for taking the time to post !

Ok, ok...

But since it's an all-moving surface then it's technically a "stabilator." :p :lol:

Thank you for you comment. Booth of you are right. I cropped a little of both surfaces the horizontal and the elevator.

FlyingPhotog Ok, ok...

FlyingPhotog I know where your coming from technically but we will leave it at that. I would hate to be in the situation flying with just the trim motors.:)

[johnathan]

Yet another version. I tried some settings in USM 30,60,1 to get rid of the haze in the background.

http://johnathan.smugmug.com/photos/478349155_qMj7M-O.jpg

[Field of 33]

I think I actually liked it better before. The hazing in the background helps the plane stand out. Now the stark, contrasty background becomes distracting, IMHO.

Thanks for your opinion. Cheers;)

If you like that background you might take a look at the 737 in this post. http://photography-on-the.net/forum/showthread.php?t=645088

I agree with Paul. The quality of the light is better (more natural?) in your original image.

[Peter Camyre]

I think the shot is a beauty!

Fantastic shot - I've been shooting landings at KMIA the last few weeks, and I can't get the crispness that you have on this take-off. Excellent work.

[tfaudree]

Ok, ok...

Beating a dead horse here, buuuuuut....
Technically it isn't. A stabilator is a flying surface that has no hinged parts. In the case of the Boeing and many other transport category aircraft, there are two parts to the horizontal tail plane, joined by a hinge; the fixed stabilizer and the movable elevator. The stabilizer just happens to move in pitch to act as a trim mechanism. The Piper line of aircraft, as well as most military aircraft, have the non-hinged tail planes that qualify as a stabilator.

The 737 has an elevator but the horizontal stab can be adjusted for trim as well...

If you look at the OPs image, there is a curved channel where the inboard end of the horizontal stab's leading edge meets the fuselage. That's where the stab ajustment travels.

It's a "hybrid" I guess because it's an adjustable stab with an elevator.

[NinetyEight]

Is it an 'Elevizor'... ? :rolleyes: :lol:

Nice shot :-)

I just spent some time on your website. You have a great representation of different carriers flying into MIA very nice.Love your photos.

For some reason I have the feeling I just read a technical bulletin.You must be an aerospace engineer . Thanks for the post and looking at the photo.

I am very familiar with the design of the Boeing pitch trim system.

Keep in mind that pitch and trim are primary and secondary flight controls, respectively. Speaking from an engineering standpoint, I don't think it is appropriate to make a relation between the two systems.

Now, aerodynamically speaking, we both know that one can't work without the other.

All true of course...

So is the "fixed" portion of the horizontal empanage mearly considered a horizontal stabilizer then (in spite of the fact that the AoA can be adjusted for trim)?

I guess what confuses me is that (generally speaking) you usually don't see a moveable tailplane and an elevator. Granted though that the "fixed" portion doesn't have the travel or primary pitch/roll authority that you find on a military jet.

Airplane Nerd Alert: My favorite part of "Top Gun" is actually the shot behind the credits. When the two Tomcats are headed off into the sunset. You see that big ol' left tail feather move and that jet is rolling right now! Very cool...

[FatAlbert]

Ok, ok...

Yeah, but all of it doesn't move as often as the "elevator" part of it, but then again, what would I know, I'm only an avionics engineer:)

Yes, the fixed portion is simply called the horizontal stabilizer. The fact that it moves up and down is merely incidental as it is the function of the trim system. It has no direct connection to the primary flight control system (elevator, aileron and rudder)

You'd be surprised how many airplanes have adjustable horizontal stabilizers. Remember the Alaskan Airlines flight that crashed in the ocean near LAX; the jackscrew that moves the horizontal stabilizer broke and caused an uncommanded pitch deviation. The Learjet that I fly has a checklist item that requires you move the horizontal stabilizer through its entire trim range at least once a month to ensure proper lubrication of the system. Due to the high speed of jet aircraft, it is advantageous to trim the entire horizontal tailplane as opposed to just the elevator portion as is common in smaller piston airplanes. A trimmable horizontal stab ensures a streamline shape of the horizontal tail plane. A rare exception is the Hawker that I fly; it has a trim tab on the trailing edge of the elevator. When the trim is adjusted on an aircraft with a trim tab, the elevator is deflected opposite the movement of the trim tab. In jet aircraft, there is actually a variable speed trim system for high and low speed flight. Typically, regular trim is accomplished through one motor and "mach trim" is accomplished through another motor operating at much slower speed.

Speaking of the Alaska MD-80; the MD-80 "elevator" does not operate directly from the pilot's inputs to a yoke. Instead, the aircraft has "servo tabs" which are essentially trim tabs. The servo tabs move in one direction as a result of the inputs to the yoke, and the elevator reacts in the opposite direction, thus causing the change in aircraft pitch. Trim is still accomplished through an adjustable horizontal stab. Take note of the elevator position of an MD-80 next time you see one parked at the gate. No two MD-80 tails will look the same, and the two sides of the elevator will be positioned differently on the same airplane.

I'll take your word for it. As I say - I'm only an avionics engineer who learned to fly in a light aircraft with an "all moving" tailplane (no separate elevator/fixed stabilizer). The Hawker that you fly may be a throwback to the traditional way I learned about aircraft control surfaces - elevators, ailerons and rudder - with their associated trim tabs - seems that things have moved on!:lol:

Thanks you all for the general aviation fundamentals refresher course. Damn now I have two engineers to listen too ha ha.:lol:

The C172SP I learned in was a fixed stab + elevator (Vs the Piper all moving tailplane design...)

As do I. I'm mearly a Private Pilot. I wish I'd have persued an A&P "back in the day" but no such luck.

I'm just another one who's greatful to those who "keep 'em flying." Be they current GA "bug smashers" or hoary WWII types, it's always the "wrench benders" that get it done!

Jay not only are you a Private Pilot your a darn good flyingphotog also !
I have always loved aircraft growing up a military brat it was in my blood early on. Four years of naval aviation got me my start at 19. Now looking back some 30 years later I am very grateful to have been involved with something I love.

Still amazes me to watch the heavy metal seem to hang in the air on landing.:cool:
