707 incremental speed brakes(spoilers)

[johnyrebbaron]

I was wondering if incremental speed brakes were modeled on the 707 panel, because mine does not work it is either all or nothing?

Thanks,

What you're observing is correct .... the way things are currently modelled and intended to work.

TBH .... I'm not sure if the the Spoliers/Speedbrakes on B707/720 aircraft were actually incremental or not.

I know they are on later types.

Thanks for the reply i have a few more question about your aircraft I just have to remember them I tried to get on your forum a few days ago when i first downloaded the dc9 and 707 but never got an activation key.
I tried again tonight and got it within two min. But overall I love the 707. i haven't flown the DC-9 yet, but it looks nice. I did work for Mesaba airlines at KALB, and ground handled Dc-9's for NWA. I got certified for pushback and towing so I know the start procedure for the -9 and from what i saw it seemed pretty accurate.

Thanks,

Gary

"SPIT'em OUT" .... whenever ya ready !

"IF" you (or anyone else out there too) is new to the HJG B707 and DC9 series aircraft and panels .... then (in respect of these aircraft) may I suggest you take time to study my following online/forum manuals for each ....

DC9 PANEL INSTALLATION & HANDLING NOTES
tonymadgehjg.proboards.com/index.cgi?board=chat&action=display&thread=3435


Similar PANEL INSTALLATION & HANDLING NOTES aids have also been compiled, by me, for each of the other aircraft types we currently host too ....with the exception of the BAe146 SERIES. These are usuallay available as "locked threads" on the various aircraft type SUPPORT forum pages .... or .... on the ABOUT HJG AIRCRAFT forum page in cases where I've not, yet, had time to transfer everything across to its appropriate aircraft SUPPORT forum pages. These aids are constantly updated and explain "most of" everythinhg that must be understood/practiced in order to be able to enjoy our aircraft/panels to the maximum.

Thanks again

I've looked at some of your documentation on-line already, I read some of it before I installed 07 -9. I usually try to read the install procedures especially when aircraft come in multiple files. Your on-line docs are good. I did not have any problems installing. My questions, when I can remember them are more general than technical. The technical part was pretty straight forward.

Below is an image of a 707-320B pedestal. The speed brake lever quadrent does show a few graduations.

How the speed brakes were actually used on the 707 I am not sure, but as Mark states on the HJG 707's its either "nothing or all".

For some inexplicable reason on my CH throttle control I have a lever on the left side which I think is used for propeller speed control on prop aircraft, and when I move it, it does deploy the speed brakes to about 15% deflection. I guess its some kind of programming error?

Thank You for the nice picture that is very clear,

I have been looking around trying to find an answer hadn't chked airliners .net. i dont know where you got that but it is a good picture.

I'm starting to learn how to make gauges, maybe someday I will try to make one for the seven- oh. I might need some help with the art im horrible at art.

I have the CHProd yoke with thr mix, and prop single engine, and the rudder pedals I would love to have the multengine thrott but I got laid off during the NWA and DAL merger still looking for a decent job. Short on cash. You should be able to remap it in flightsim or set up a profile in the ch software 1 for jets the other props.

I did check this earlier on today .... because it's been a while since I last fiddled with any of the B707's.

Increments do appear to be featured along the side of the Spoiler Lever track, but, the Spoiler Lever is, indeed, an "all or nothing" animation.

SORRY !

Hi Marc,

Don't worry the incremental speed brakes, I got looking and I couldn't find but one or two birds in the hangar that did have them. i thing my PMDG's have them but I'm not sure since I haven't reinstalled them after reloading my system awhile back.

I guess the reason I thought of them was that the seven-oh is awfully slippery if you want to bring her down quick, she don't want to slow down to easily. I might need to reread your operationg procedures again on descents.

I probably will not post back on this thread except for a reply to me personally, or unless something earth shattering pops up on it.

Thanks,

Gary

It's easy to go "down" .... but .... maybe not so easy to "slow down" whilst "going down" .... at least not for the uninitiated ;D

Forward planning .... and good planning in particular .... are essential when flying the B707's .... and even more critical too when flying the DC8's since the spoilers on those aircraft (DC8's only) can't be used inflight at all (and that's a realworld limitation as well as an FS one) without getting one into "SERIOUS TROUBLE". In order to increase descent rate DC8's were certified to use inflight reverse thrust on their inboard #2 and #3 engines only.

With the B707's .... spoilers can be used inflight, but, I generally like to start down early (from 150 DME from my destination airport assuming it's elevation is around SL) .... reducing power just prior to starting my descent (which also helps keep the speed under control throughout the descent) .... adjusting my ROD at various stages on the way down .... and aiming to be at/around FL100 and 250 KIAS by around 30 DME from my destination airport.

It all takes a bit of practice to master .... BUT .... once mastered .... it really becomes "A BREEZE" !

I was always taught/advised (by a senior B767 instructor for a major South Pacific based airline) that if everything goes "to plan" during descents, then one shouldn't need to use the spoilers to assist their getting down more quickly .... unless ATC bugger everything up (which they apparently can do) by wanting one below a certain FL within a particular time frame or distance from any destination/position.

Just "FLY THE CRAP OUT OF THE SIMULATION" .... and you'll soon get the hang of it !

Hi Guys...

I just looked at the 707 manual and it says the speed brake levers has a 10-degree increment scale, from 0 to 60. It has a feel detent at 30 degrees.

So it can be positioned at different angles as required, although its real position is also determined by air speed.

When landing, the speed brake must be fully deployed and that's the way FS simulates.

BTW, that picture above shows a 707 with auto throttles!

[aerofoto - HJG Admin]

"GOOD" to se you around Harerton !

BTW .... some B707's and DC8's were equipped with a form of AT, but, according to John DETRICK, whom flew the DC8-61/62/63/71/72/73 for ATI, as a PFE .... and for quite a number of years too .... the AT system on those DC8's equipped with it (and we have to assume this applies to those B707's equipped with it also) never worked particularly well .... hence a the majority of airlines/operators either never relied upon it, or, simply never used it at all.

Yes, I'm still alive... but due to my PHD studies I'm grounded!
