I found this wonderful Italion airliner that almost resembled the Lockheed Constellation, I had to put in fuel tank gauges for it. My attemps to flyit at high or low altitude I am afraid met with disappointment as the airplane liked to porpose up and down...how can I stop this from happing?


Cheers

Breda Zappata BZ308

Pete,

Here it is..Breda Zappata Bz308 Airliner for FS9 on Fltsim.com propliners, E-mail of author is Capt I D'Attmo at mdattom [at] tiscali.it.

Thank You For Your Help

Casey
 
Thanks Casey.

I've found it and installed the beast.

Took it for a very quick flight without any problems, but tonight if I have time I'll try it out some more.

If this porpoising happens at high indicated airspeed you would need to first look at what ever data you can find of the real airplanes capabilities. It may just be going too fast in the sim...at which point you have either manually reduce speed or mod the engine power.

If it happens when you have AP ALT hold engaged you could possibly play with the elevator trim effectiveness number in the aircraft.cfg. It may be a bit too slow making changes and created the "hunting" you experience.

For an airplane like the 308 there is usually very little real data available so a developer might just use a best guess based on what ever is known such as the engine type, size and weight of the aircraft.

Lovely air Plane,Installed it in FSX,flys nicely...but its a Flight of fancy,as it seems none ever make it to the ticket buyers!


Called the italian Constellation, the B.Z.308 was a large low-wing monoplane of all-metal construction, the fuselage had an oval cross-section. It had a large tailplane with endplate fins and rudders, retractable landing gear. Powered by four Bristol Centaurus radial engines driving five-bladded propellers, it was designed for a flightcrew of five, and 55 passengers in two cabins, a high-density model was planned with seats for 80. Although flight testing went well, financial problems and the realization that competition from American-built airliners would take a major share of the post-war airliner market, along with the pressures to close down the Aeronautical section of the Breda, led to the project being abandoned. Breda stopped producing airplanes subsequently!

I aliased the sound to the 4 engine Bristol Hercules Soundpack as I don't have a 4 engine Bristol Centaurus set available
 
A common problem upon landing

Is this a FS issue or a piloting issue:
often times upon landing an aircraft will balloon i.e., jump up an down for apparently no reason, eventually leading to landing gear collapse.

Examples: new PAD-CASA turboprop.

I have tried to reduce speed to almost stall at the point of touchdown and applying brakes gently. Sometimes it works, sometimes it does not.

Any solutions?

Thanks,
Sid
 
Something wrong with the contact points (effects related)
Touchdown effects (smoke and sounds) shown before main landing gear touch effectively the runway !

No, just something wrong with the contact points, period! Just had a look in ACM and everything is way off; I'll see if I can find time to look at it later, if I do I'll put the revised values up here.

Thank you for take care ...
I have a problem with ACM .. as he give me a error message
I think I have too many planes :) and the ACM software must have a limit about the number of planes ...

OK, bigger project than I thought, but I have some free time tomorrow so I'll look it over properly. When I opened it up in ACM and had a proper look it is not just the contact points that are off; the datum & CoG points looks suspect, the fuel tanks are behind the wings (and the CoG), the engines are in the wrong place .........

Well, you get the idea. All of that could easily explain the porpoising, it certainly explains the effects issues. This may be beyond me, I am a dabbler, not a guru, but I'll give it a stab.
 
I can be wrong on this one (not possible to check with ACM) but maybe effect showing before wheels touch can came from wheels diameter .....
