bin801 0 Posted May 10, 2009 Share Posted May 10, 2009 I can hardly to accelerate it and climb, so I think maybe that is due to the full loaded fuel, then I turn the fuel dump switch. then I cry... my Catalina only dump fuel from left tankand I did search in cockpit and manu, can I dump from right tank? or first choice, can I dump fuel from both tanks simutaniously? and is there any fuel cross feed swith can balance the Cat?thanksand BTW, with full power used, the highest speed I can reached during climb is 11, lower than the data show in manu,how come?and many times, even I use stage method to climb, but I still can not reach the ceiling 15,000 ft, even 11,000is that because the fuel load is too heavy?thanks Link to comment Share on other sites More sharing options...

vgbaron 2 Posted May 11, 2009 Share Posted May 11, 2009 Check hat You have 2700 RPM and 42 inHg MAP.FinnThis brings up another question - I am at work and don't have the manual handy to look there but - I use a CH yoke and throttle quadrant and have the throttle/Props/Mix mapped accordingly. Following your guidelines I leave the props and mixture at full 'high' or 'rich'.How then am I to adjust the RPM? The throttle will adjust manifold which will slightly affect the RPM but is there no manual adjust for prop pitch, ie RPM? Or are you using the throttle to adjust the MAP and RPM simultaneously?I promise I'll reread the manual when I get home! EDIT: Couldn't wait so I do/l the manual. Seems I misread something, the mixture controls stay full forward but the prop controls work as expected.Vic Link to comment Share on other sites More sharing options...

sparrows 7 Posted May 12, 2009 Share Posted May 12, 2009 hmm, i use ch yoke, and with my prop axis i can reduce rpm very well. Link to comment Share on other sites More sharing options...

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted May 12, 2009 Aerosoft Share Posted May 12, 2009 Yes - thats what I´m trying to tell in my former post.Propeller levers can be assigned and used just like on all other aircraft.FinTo enhance on this, if you flatten the prop they get less 'bite' and RPM will rise. When you pitch the blades so they 'bite' more they will have much more drag and this will reduce the RPM. So in that sense the prop pitch lever does control RPM.If you change the pop setting in level flight you rpm will always change. Link to comment Share on other sites More sharing options...

VulcanB2 5 Posted June 2, 2009 Share Posted June 2, 2009 Ive got loads of power!! (sorry for small screenshot)Is it an edit or for an update? On the subject of fuel dumping - is it OK to fly with such an asymmetric loading, or is this an abnormal procedure? Best regards,Robin. Link to comment Share on other sites More sharing options...

Best regards,Robin.I guess the purpose of the fueldump on the Cat, was if it was battle damaged during WW2. Only one of the fueltanks whas seflfsealing on most of the Cat's.If the non sealed tank was hit, balance could be kept by dumping fuel.Finn Link to comment Share on other sites More sharing options...
horst18519 231 Posted June 3, 2009 Share Posted June 3, 2009 The fuel dump is a pretty cumb thing in fsx. First you cannot choose which tank should be emptied, then the aircraft balance is 100% weird whily dumping. Try it by parking your aircraft on ground. Start dumping. Although the aircraft would be expected to lean more and more to the right (because left tank is emptied first), it starts to lean right, then suddenly raises again, leans again,...From that you can see that the fuel weight calculations are all messed up in FSX. There's nothing an aircraft developer could do about this, not even those genius aliens ( ) that made the Cat. Link to comment Share on other sites More sharing options...
