hi,
i just wondering, i made a flight from Kuala Lumpur Malaysia to Los Angeles CA USA direct flight. i flew with a380, and in real life, B747 can reach there directly without stopping anywhere. and the fuel for 747 is more efficient and not run out. when i fly with a380, if im not mistaken, after 8-10 hrs, i ran out of fuel? how can that happen? a380 designed for long distance flight. anyway im using Abacus airbus a380. so, i have to tick box on "Unlimited Fuel". is there's anyway or tutorial about fuel management about how to save fuel and stuff? when i look at the fuel meter, it drain out the fuel like water, the digits going down so quick, do i have to reduce my speed to certain amount at 30,000 feet?

another question is, everytime i have my long distance flight, when i touch down, and taxi to the gate, i dont understand my plane become bumpy, and lots of smoke came out from wheels while taxiing, as long as i move my aircraft, and the sound effect sounds like boom.. boom.. why is that? while taxiing, my speed is just 5-10 knots.

and other question, after land, how come i only got option taxi to parking etc.. but not taxi to gate? but i did sometime asked to park at the gate. can i ask ATC to park me at the gate instead of them deciding me to park at parking wherever they want. because when you contact with ground control, we just rely on 'em to guide us where to park. know i mean?

thanks in advance..

Are you flying with your throttle wide open? If so, back it off a bit to conserve fuel... Wink

lets see here

The bumping is due to the contact points for the plane. I am not sure how to fix that but it can be done

The Airport might not have a gate to fit the size plane you are flying. This also can be fixed with FSXPlanner by either adding a gate or making a current one bigger

As far a fuel mileage, I cant help there

THe fuel issue could be an issue with the model.  Which one are you using?

ok, if i back off my throttle at 30,000 ft, isnt it making my plane stall at that altitude? can you guys help me, at 30,000ft, what is the recommended speed?

FSX planner? where can i get it? can i manage it with me own option? can you please explain more detail (if you dont mind) what is it do?

like i said i flew Abacus A380.....

I didn't say back it off to 40%... Grin

I dont fly big birds but this is what I know:

Flying is not about climbing to your desired altitude full throttle then leave it at full throttle eg.

I fly props, and things like manifold preasure, RPM's, mixture controll and prop controll is very important to be tuned.

You can set the above to facilitate econo cruise, long distance cruise, the way you set em determine how long your fuel last. Help me if I am wrong here.

Donno how the big turbine jets work but im sure you have to also adjust the turbines to econo to enjoy long flights.

I strongly suggest you try and get a copy of the real life manual. That would give all the details.

Goodluck  Wink

That would be a contact point thing.  The key components are; static compression, compression-ratio and damping-ratio.

Static-compression is how much the suspension "gives" when the plane is sitting still.

Compression-ratio decides what percentage the static-compression is, of the suspension's total travel.

Damping-ratio is like the shock-absorber strength.

It's a tricky thing to get it right for all conditions.. I'd suspect that the designer of the plane you're flying, never tested it for near-empty taxiing (as in all your fuel is gone after a long flight).

Here is a sample line in the contact-point paragraph from a 737.. just so you can see what it looks like.





       //0  Class                        <0=none,1=wheel, 2=scrape, 3=float>
       //1  Longitudinal Position        (feet)
       //2  Lateral Position             (feet)
       //3  Vertical Position            (feet)
       //4  Impact Damage Threshold      (Feet Per Minute)
       //5  Brake Map                    (0=None, 1=Left, 2=Right)
       //6  Wheel Radius                 (feet)
       //7  Steer Angle                  (degrees)
       //8  Static Compression           (feet)  (0 if rigid)
       //9  Max/Static Compression Ratio
       //10 Damping Ratio                (0=Undamped, 1=Critically Damped)
       //11 Extension Time               (seconds)
       //12 Retraction Time              (seconds)
       //13 Sound Type
       //14 Airspeed limit for retraction     (KIAS)
       //15 Airspeed that gear gets damage at (KIAS)
       
[contact_points]
point.0=1,  40.85,   0.00, -10.20,  1600, 0, 1.442, 55.92,
0.6, 2.5, 0.9
, 4.0, 4.0, 0, 220.0, 250.0

What is your current setting for the target FPS limit ?

You need to look up the recommended cruising speed for that plane. For example the 737-800's is Mach .78, I usually fly somewhere between 35,000 and 40,000 feet. You can see your Fuel Flow on the control panel as well. At a higher altitude you FF drops (but only so high).

In answer to the fuel problem... I wouldn't know about the big jets as I am a fighter jet flyer mainly, but I have found that backing off the throttle definately helps with the econoy rate.. For instance I tried to fly an F15 across England from one side to the other and ran out half way because I was using full throttle. I then tried it again being economical with the fuel, and had loads left at the end!! Hope that helps
