In a article at Prepar3d 'Fueling and Loading Aircraft' it discusses the importance of understanding the centre of gravity.

having said that I'm having a problem in achieving the correct c.o.g when adjusting fuel or payload, just can't get it to be inside the limits, its always appears forward of the limits shown . Have zero'ed fuel and payload but it doesn't seem to have much affect.
Just wondering if any one else is having the same issue.

What aircraft is this with? Some aircraft show the incorrect C of G regardless of fuel/weight distribution. I don't think "out of CofG" dynamics are modelled in P3D anyway. Anyone know?

Its both default and addons, (Turbine Duke and Alabeo P32 Saratogo)

at the moment the c.o.g is shown as being right in the nose. but in flying they don't appear to be elevator heavy.

ps this in P3D ver 2.5 hotfix ????45

Don't own anything by Alabeo. I've not had  a problem setting CofG in the Turbine Duke. Maybe Rob Young from RealAir will see this thread and pop in to help.

 

I'm not sure why some aircraft show an out of trim CofG regardless of what we input. Maybe it needs to be modelled in the aircraft.cfg for it to show correctly in the fuel and weight section.

 

Lockheed Martin really need to address issues like this if they want to be taken seriously with P3D. Weight and Balance is something we teach early on in BASIC pilot training due to the dangers posed by out of balance aircraft. The 747 crash at Bagram airbase a few years back show how dangerous an incorrect CofG can be (due to shifting cargo - no fault of the flight crew).

That dialog is never... and I really do mean never used in training. Zero value.

Are you posting in the correct thread? No idea what you're talking about!

He is correct. As the pilot, how do you know what the centre of balance is?

Are you asking me this question? If so more info (for example) here.

Weight and Balance calculations are one of the most important pre-flight actions. Working this out will determine the CofG for that particular weight/distribution.

 

In P3D you add/subtract fuel and passengers/cargo to keep it within the simplified diagram available in the settings menu.

Well, that's scary.

 

The OP is discussing the "Fuel and Payload" dialog built into Prepar3D. They are talking about how all of their aircraft appear to be nose heavy whenever they set the fuel and payload, based on the position of the CG graphic in the "Fuel and Payload" dialog image.

 

I stated that the dialog is never, ever used for training. When training someone to do weight and balance... it's always done on paper using actual weight and balance worksheets for the aircraft as well as the weight and balance certificate that provides the empty CG value(s).

 

You as a pilot would never, ever know visually where the CG is at all. You can only do math on a piece of paper.

 

Thus... the dialog being discussed (which may or may not be displaying correct CG information)... is never used in training.

 

Now do you have an idea of what I'm talking about?

On my  basic flying training we never checked that as a pre-flight action.

WarpD Yes you're correct that "dialog" in P3D is not used in real-world training. Hence why I think LM should change the way it is displayed/changed if they wish to provide a professional flight simulator.

You were never shown how to complete a weight and balance sheet before each flight?

No - what would be the point?

For just pattern/circuit work by yourself or with your CFI, it's not important but if you ever flew to Aspen Colorado or some other high altitude airport with some friends, you would really want to know how your weight and balance in the a/c profile. One of the major causes of GA accidents is overloaded a/c.

 

Other than for practice, I don't recall doing it for my general flying around but there were plenty of times when I felt it necessary to insure safety. Hot summer days and high altitude facilities are a killer for the unwary.

I flew in the UK where we don't have high/hot airfields. That's why I never needed to complete a weight and balance sheet before each flight

I fly in the UK and do a W&B check before every flight. I won't fly with a pilot who doesn't as they aren't a pilot, they're a gambler.

Hot and high has very little to do with weight and balance.
