DC-8-63 Performance Update?

[investdude]

Those of us who fly the DC-8-63 a lot are still hoping for a performance update which has been promised in the past. I realize there is a lot of work involved but it would be much appreciated by us DC-8-63 pilots. Any hope?

Actually .... it wasn´t "PROMISED" .... as such

I simply said I was working on it .... as I´ve been doing for the past almost 2 years now (and not for just the DC8-63´s either, but rather, it´s a general DC8 FDE upgrade) .... BUT wHICH .... subject to realwold issues (including a family breavement last year) I can only progress "as it is convenient for me to do so".

It´s a very big project and one that requires a lot of time and energy .... "if it´s to be done properly" .... BUT .... it "IS" still happening regardless .... and it "WILL" be delivered here .... however .... I´m simply not prepared to commit to any particular date or time frame

Hi friends:

As I have since Marks last post a little flown a DC-8 62 (Aeromexico what else?) I find that besides some FDE issues like coming down from the flight levels cannot be done by the book of the real DC-8 62 you must go much slower, Hermannkermes has written about that in another thread, but was is sorroly missing are the slats of the higher numbered versions as well in the visual outside model as well in the flightmodel. The behaviour of the panel was not a problem. Will be adressed this in your efforts Mark?

missing are the slats of the higher numbered versions

You may be confusing the DC8 wing with that of the B707 .... I think.

DC8's have a "SLOTTED" wing (leading edge) rather than a slatted one.

As for the current FDE shortcommings .... particularly in regard to the DC8-62 and -63 ....

We know about these (as I've commented a number of times in response to other recent postings) .... and these "ARE" being addressed .... both to the best of our ability and in accordance with "certain FS imposed limitations" too

as well in the visual outside model

There will be no alterations/changes to any of the current HJG DC8 3D/visual models though .... since that simply "IS NOT" possible.

Sorry for the confusion slats slots. In may post to Aharons Air Jamaica Flight this was correctly stated. What is my point: Having models of other airplanes which correctly represent the basic design features of their real counterparts correctly (also slotted wings like on the later DC-9s) seeing the DC-8 with that wing makes feel one realy sorry. Other shortcomings of the modelling like the behaviour in descents pale in comparison to that.

Kind regards

"WING SLOTS" were first introduced with the DC8-20 .... from C/N # 45291 L/N # 30 (delivered to UNITED AIR LINES as N8018U on February 28th 1960) .... and then retrofitted to earlier production DC8 aircraft and became a standard feature of all following/later production DC8 versions.

They remained of a standard size .... located under the wing leading edge and between engine pylons .... on all modified DC8-11/12 through DC8-61 aircraft, but, for the DC8-62 and -63, these Wing Slots were enlarged, somewhat, as part of the wing redesign which was applied to these particular later production DC8 aircraft versions.

Unfortunatelty .... the Source Code for all of the HJG DC8 models/flightline is no longer available, so regrettably, there's no way that these features can be added to any of the current visual/3D models (although the current DC8 panels "DO" feature a working Wing Slot anunnciator lamp .... which illuminates, briefly, when the wing flaps are extended/retracted through 7 degrees) .... and short of completely new DC8 models being designed/built, but which, simply "IS NOT" going to happen.

I have addressed the issue concerning the physical modeling of DC-8 wing LE-slots in the past.
In brief: It was not an overlooked detail. It was never going to happen because of their small size. If I were to build a completely new DC-8 model today, they still wouldn't be included. Static texture detail at best.

I hope that clears it up. Now, you are cleared to your assigned altitude. Precede as directed.

And remember: Fly the airplane FIRST!

Hi Mark! Hi Dee!

O.K. Even the world of FS is not perfect! So I report to "ATC" a change of equipment "inflight" (IL 62 e.g.) and go on as cleared!

Hi guys! I was a little confused as to why you are working on updates of the current models as the last I knew was that HJG was busy with Mr.Faos on an all new DC-8. Having done a Google search I see you are no longer involved but the project still exists but is hardly progressing at the moment. It was looking very promising a while ago ...

I was a little confused as to why you are working on updates of the current models

Allow me to clarify please .... just for the benefit of "some"

HJG "IS NOT" working on updates to the current models .... and by that I mean the current HJG visual/3D DC8 madels.

The "updating" recently discussed within this, and previous, threads relates to various "FDE/flight modellig improvenmentrs" only .... and .... when the time comes (for its release) .... these will be all that can be offered as improvements (and extentions) to the current HJG DC8 flightline.

It was also posted, on this forum, some weeks ago, that HJG had opted to withdraw from "the other" freeware DC8 project.

Sorry Mark, I'd not seen the post on HJG withdrawing from the DC8 project. I'm looking forward to the "FDE improvements" you're working on since I like flying these birds a lot. For me that is a sort of "update", but I know what you mean

Greetings,

Albert
