Well, there you have the answer then:
You should never touch the trim with autopilot engaged...its fighting one against the other.
If autopilot is engaged, IT controls-adjusts trim.
I can imagine strange thing would happen if you touch the trim with AP engaged, (Ive never even tried it), nor thought someone would, so the bouncing could well be because of that.

Another example: Its like switching autopilot altitude hold, and then try and climb or descend..."why would you do that ???" its common sense, (no need for a pilot licence on this one) either its autopilot or manual, if its autopilot..DONT TOUCH stabilizers.



Ok, I am now confused. My understanding of the 707 is that it will not do the equivalent of an ALT SEL and that you need to adjust pitch to climb to the appropriate altitude. Now if I am flying a flightplan entered either via the INS or through the FS flightplan load then I need to have the AP on. Have I misunderstood something?

BTW I just tried another flight with the same result - this aircraft unfortunately is becoming unflyable for me - back to the A300, which doesn't exhibit this sort of behaviour.

Hi balus.

Are you using the Pitch Trim Wheels (enclosed green squares in the image) on the Autopilot (2D and/or 3D VC gauge) to adjust the climb/descent attitude? That's what they are there for. I use them all the time for controlling the 707 during the climb and descent phase.

yes Mark that is what I am using - sometimes they are animated, sometimes they are not.

BTW my A300 flight was a complete success Smiley

perhaps my dumbest post of the day, but have you tried disconnecting the ap elevator control? It's to the left of the autopilot control window.

I assume you have, but that's my best guess as I can't reproduce the issue.

So there I was on climb out of Singapore and the 70 starting bouncing, the yoke in the VC was oscillating backwards and forwards - spot view showed the elevator up and down in full deflection. Now I know I was flying a Qantas livery but I didn't order a kangaroo!

I pulled back on my yoke but there was no change - removed mappings in FSUIPC but still no change - ended up having to abort the flight, which is always disappointing. Any ideas as to what caused it?

For those who experience problems!
You should never play around with the flight controls, when the autopilot is engaged. If you do that you will disturb the system and it can result in errors.
I have experience in the real world 707, and I fly the Captain Sim 707 just like I did with the real thing. And I have no problems what so ever!
It is working perfectly fine... Maybe its something you guys are doing wrong, I don't know. But I don't have any problems at all. It works absolutely perfect for me.

I had this happen on my last flight in the 707.  I was climbing through FL280 for FL300, and was adjusting the A/P pitch controls downwards, in preparation for the top of my climb.  The plane suddenly started porpoising through the air, with the elevators deflecting full up and down, rapidly.  I immediately disconnected the elevators from the A/P, and stabilized the aircraft manually.  When I attempted to reconnect the A/P for altitude hold, the plane suddenly and violently pitched upwards, (we're talking 6000fpm of upward pitch) and stalled.

I know I saw a thread somewhere that addressed this problem, but my 707 seems to do alot of bouncing when you switch views, any ideas or point me to that thread I can't find?

Couple of notes, FSX has always been a performance killer and I have been out of the loop for about 3 years...my new I7 2600K with my GTX 580 seems to do the trick (and I have not overclocked it yet).  I bought the 727 and 707 and the expansion packs for FSX (had the 2004 version years ago) and I cannot get over how great they both look and fly...even if I am only using the keyboard at this point!  The install and verification system Captain Sim is using is heads and shoulders above what it was years ago as well.  I can't wait to eventually see these babies in 3d and down the road have full immersion 180 wrap around goggles or the Jdome...  I can put the 727 down in a parking lot, but the 707...two words to describe her....NEED ROOM   Grin

boeing727223,

Get a joystick! Then you will really see how nice both these planes fly.
Your I7 and GTX make a good system to run FSX.
The 707 will take a few more feet than the 727 in rollout, but you ain't seen nothing 'til you try to stop the Whale (747).

I'll let Mark or CoolP advise you on you jumping jacks.

Thanks Lou!  I have a Jetliner yoke, pedals, and quadrant with the 2, 3, and 4 engines..but I bought them 10 years ago so I need to get a seriel PCI card since PFC said they can't be converted to USB. 

Yup, the 727 is solid, but if ever not getting behind the power curve applied to any aircraft...the 707 is Queen (behind the 747).  I ended up dumping a 321B into San Francisco bay last night.....keyboard has got to go!!   Wink

I'm not gonna complain because a buddy of mine flew the DC-8 sim at UPS in Kentucky and the 707 is a Cadillac (keep it in trim), but the DC-8 is a Mack truck with no powersteering!  You have to be miles and sunshine ahead of that bird!!

It it doesn't work out with your hardware, I recommend the Saitek Pro Flight yoke, throttle quadrants, and their rudder pedals.  You comments on the 707 and DC-8 handling remind of a conversation with my father-in-law.  In his experience, he says the 757 flies like a truck, while the 767 is like a Cadillac, and is much lighter on the controls.

Hi.

I think this is the thread (Topic) here: http://www.captainsim.org/yabb2/YaBB.pl?num=1294399965.
I'm sure I saw that the fix for this problem was something to do with changing the contact points in the aircraft.cfg. I can't remember if it was for the 707 or for another Captain Sim aircraft.

Yeah audiohavoc, I will go that way if I can't get my old rig up and running...

Thanks Markoz, I notice that the problem seems to be when I change views and sometimes airport vehicles do the same....727 seems to be no problem....I hope I didn't just jinx myself!   Wink

I still can't get them to stop hopping up and down, and i can't do much as sit on the tarmac with them without this!  Any more suggestions? I already tried teh reinstall of teh E-3 and VC-137.
