I can't see unusual on the screen. The KIAS is ok for this rate of climb. What is your GW on this screen?

It would be helpful to show also screens from the overhead panel and the engineers panel.

I also recommend the excellent addon "V-One" for the 707.

EDIT: One thing on the screen seems to be not correct: The fuelflow is to low. When you have the throttles near maximum, the fuelflow on this alt should be over 4000 PPH (near 6000 I guess) at each engine.

Thanks for that re:fuel.

I loaded with 30% each tank, 100% wingtip tanks.

Using ACE I loaded 174 pax and GW was 14766 kgs

Just downloading that V-One.

The problem is not the amount of fuel but I guess there could be a problem with the Thrust-Lever. Check your Thrust-Axis if you have 100 % range.

What Controller do you use? A Joystick?

For first Testflights I recommend very few payload, only 2 or 3 stewardesses or so  Grin

Just installed the very latest V-One and followed all the instructions to the letter, yet under the 2nd SimIcon, the one that looks like a T, when I click it, I see zilch.

What could I have possibly done wrong here?

Mark, can you kindly PM me your aircraft.cfg for the -300C?

Thanks.

Download it from here: https://www.dropbox.com/s/ewm2jspg03td6al/aircraft.ORIGINAL.cfg?dl=0

I'll leave this there for a while, then I'll remove it. Wink

Don't you want to solve the "Thrust-Problem" first? Anyway, make sure you have a subfolder in your \panel Folder called "V-One" with all files in here.

And don't forget the entry in [Window Titles] with the corresponding number. Mine look like this:

[Window Titles]
Window00=Simicons
...
Window09=V-One

.
.
.

//--------------------------------------------------------
[Window09]
Background_color=0,0,0
size_mm=480,60
window_pos= 0.0, 0.055
position=0
visible=1
ident=130

gauge00=..\..\CS_B707-300\panel\V-One!V-One, 0,0,480,60

One think about your "Thrust Problem" you can test:

Open the aircraft.cfg an go to this section:

[TurbineEngineData]

search for this entry:

inlet_area=10.0          //15.0

The Originalvalue is 10.0. I've tested higher values, but I was not satisfied with the performance. Maybe that solves your problem. But keep in mind that there could also be a problem with your joystick/thrust axis.

Hi Mustang1972.

Thanks for your input.

Got all those entries in the aircraft.cfg and in the panel.cfg.

That is what is baffling me. I have edited panel.cfgs and aircraft.cfgs several times before, and I have followed the latter version of the V-One file I found on Avsim, to the letter.

Made all the changes to aircraft.cfg and the panel.cfg using the first version of V-One and this time I got to see all the data on that scratchpad by pressing that 'T' icon.

However, I was no further down the road in getting this plane to climb to the 35000 shown on that V-One scratchpad as can be seen from the image.

The speed is falling off, the climb is no better, and all that despite a 50% fuel load. I am at my wits end with this plane.

There is something else going on here, your pic shows that you are doing nearly Mach .7 which is way out and the barber poll on the ASI is way too low. Do you have FSX set up to display IAS or TAS? Also, are your settings in metres or feet? What weather program, if any, do you use? It just doesn't seem to add up. The climb is probably correct for doing Mach .7 at 12,500 metres.

Cheers Nathan.

His speed may be MACH 0.7, but the airspeed indicator shows about 190 knots and that is way too slow, even at 12,500 metres. Shocked

Attention, 12.500 metres are near 41.000 feet - 190 KIAS for that alt would be alright.

@Colvale: Once again, on your new screen, your fuelflow is too low! Only 3000 PPH with (i guess max throttles) on that alt is incorrect! It should be around 5000 PPH. There have to be a problem with the Throttles/fuelsystem.

What show the Tooltip when you hover over the throttles at full throttle? It have to be 100%.

It would be helpful to make a screen of the engineers panel. Maybe you haven't activate all fuel boost pumps?

No weather program, other than FSX's set to fair weather. As I wanted to load fuel and pax in kg, opted for metres as I could not figure any way to load in kgs.

Thanks, Mustang1972, I now realise the gaffe of 12000m=41000ft. I tried to copy your aircraft.cfg and and immediately lost all 707 aircraft in FSX, i.e. no 707Captain displayed, so reverted to the saved .cfg.

Will check that tooltip hover next flight.

Will do Engr's Panel, but I can confirm ALL fuel pumps and Boost Pumps are on. The only ones not switched in-line are the Reserve Tanks fuel switches.

Whooppee! At last, today I managed a 900-mile flight, without a hitch. Cruised to 31k as smooth as silk, and the the entire flight envelope was all that I had hoped for.

That was in FSX-MS. Next try, in FSX-SE.

Many Thanks to to you two, Mustang1977(apols for calling you 1972) and Markoz.
