I have the Posky 777-200 and have noticed that I have to have a minimum speed of approx. 220

 

before the aircraft takes off by which time I am crashing into the airport surroundings like buildings.

 

Usually the take off speed for other models is approx. 180.

 

Is there some way I can resolve this issue, for example by changing something in the aircraft file.

 

Other Posky models which I have seem to be oke.

 

Any suggestions welcome.

Which flap and trim settings do you have?

And what is the take off weight of the aircraft? Even 180 knots is too high at max take off weight

Thanks for your replies

 

I am not an expert pilot so I do not set anything.

 

I just use  my joystick to start and take off.

 

I do this with all my aircraft without getting the issue with Posky.

Hi again Although the posky 777 is a simple representation it is likely whoever designed the flight dynamics put some effort into simulating the behaviour of the real aircraft.

 

It is important to understand some basics like weight and balance. Simply loading the aircraft up with a random amount of fuel and cargo will likely lead to frustration.

 

At the very least reduce the weight and fuel load and give it another try.

 

Regards

Found the solution as mentioned above in the Weight & Balance section in the Aircraft file.

 

There were cargo & passenger weights, disabled them using //.

 

I am now getting a take-off speed op approx. 175, and  before the end of the runway is reached.

 

Once again thanks for your advice.

Because with large commercial jets, you do not just jump in and take off. You need to set the flaps, as they're there to increase wing area and lift. On the 777, you can take off with flaps 5 or flaps 15. If you're not using flaps for take-off, that would explain why you're taking off at 200 knots since the wing isn't able to generate enough lift.

Even 175 knots is too high unless the plane is very heavily loaded, and commenting out the cargo and pax weights is not the way to go.  You should put those back.

 

You need to check how much fuel you have.  Typically, FS loads a plane with full tanks, which means that, in the case of a 777, it will be well over maximum takeoff weight.  You reduced the load by eliminating pax and cargo, but you need to focus instead on fuel.  If you figure about 15-16000 lbs of fuel per hour of flight, plus another 10,000 for climb to cruise altitude and an extra hour's fuel for contingencies, that should give you a reasonable fuel load.  Fill the wing tanks first, then the center.  Rarely will all three tanks be full.  In a real world United video, a 777-200 going from Chicago to London had @ 135,000 lbs of fuel -- way less than maximum capacity.  Opensky 777s are not very far off from real in fuel consumption.  In the FS Aircraft fuel and payload tab (where you can change the fuel amount), make sure the total weight isn't red, which would mean the aircraft is over maximum takeoff weight.

 

As Kevin said, you need to use at least 5o of flaps.  You also need to pay attention to trim.  On an Opensky 777, about 5 trim up for lightly loaded, about 7 for heavily loaded.  If you have a proper fuel load and are well under the maximum gross weight, it should rotate well below 175.

Hi, Christiaan,

 

I just loaded an Opensky 777-200, 16038 lbs over max takeoff weight due to full fuel, and a 777-200ER, 21667 lbs overweight for same reason. 

 

I also found tables for V speeds.  For a fully loaded (572,000 lbs total weight) 777-200 with PW 77000 lb thrust engines, V2 (takeoff speed) is 163 for flaps 5.  For a fully loaded (660,000 lbs) 777-200ER with PW 90,000 lbs thrust, V2 is 175 for flaps 5.

 

I have used a V Speed gauge with data derived from these tables and they take off when they should.  There is a V Speed gauge by Rob Barendregt. It shows V speeds for various flap settings and lights up red if the plane is overweight.  If you know how to install gauges and download it,  I can send you files customized for the various versions of the 777.  I've used them with Opensky panels, mostly merged with PSS panels.

 

Mike

Yeah, because the simulator by default loads maximum fuel, which if you're also carrying maximum payload, is going to make you overweight. It's a balance between payload and fuel, but you can't have maximum payload and maximum fuel at the same time.

1. buy fsx

2. buy pmdg 777

You forgot to add number 3. Spend at least 1500UKP (2200USD) on a new PC capable of running 1 and 2. :rolleyes:

 

Some people are happy with FS9 believe it or not.

Ray, how are you finding that 780? I have picked up a 780Ti but won't be able to test it for a month. My last card was the 670FTW.

Hi Rob,

 

Really pleased with it. My previous card (for FS9) was a 8800GTX but of course I've since migrated to FSX. You won't be disappointed with the Ti which is even more powerful.

Good to hear! Am looking forward to giving it a test run.
