Overpowered?

Print Post  
Is anybody getting the impression that the 737 is overpowered? I took it up with a gross weight of about 85,000 lbs and ended up with a climb rate well above the range of the VSI. I was climbing a thousand feet in just a few seconds--it was like flying a fighter jet. Is there a flight dynamics mod to correct this?

Yes. They're like a rocket ships!

I have changed (decreased) the static_thrust settings for all of the 737's. These:

737-100 - 14500
737-200 - 16000
737-200C - 16000
737-200F - 16000
737-200 ADV - 17400

Even with those settings, they still feel overpowered, but not as much as they are with the original settings. Grin

Thanks for the numbers. This actually makes the EPR settings in the PDCS usable.

The FDE needs to be done properly. There are some user tweeks but the plane needs CS to finish it and fix the bugs. I thought it would have been done by now. No such luck. I haven't given up on CS, just want the plane finished.

I just finished a flight in the 737-100 (Continental) from KSEA - KSFO as a part of my checking out Captain Sim FSX products in Windows 8. I was 81,400 ZFW with 20,400 pounds of fuel (101,800 GW) and it took a while to reach FL300.

It certainly did not feel like a rocket ship using the 14500 for the static_thrust. It may not be perfect or realistic, but it "feels" better to me. Same applies to the rest of them, although by the time you get 737-200ADV, it feels quite zappy.

I am noticing the "zippy-ness" but it doesn't bother me too much. I will give the new thrust values a shot.

Thanks for the new values, Mark! Are there any other variables that should be adjusted? (e.g. drag variables)

And as a side note, the door coordinates seem to be off. Does anybody have fixed coordinates so the jetways properly lines up with the door? The jetways seem to want to line up right between the front entrance and the wing for me.

Two threads sum up the current FDE variants. Happy testing.  Smiley
1) Bud's mod. http://captainsim.org/yabb2/YaBB.pl?num=1339198966
2) Ryan's mod. http://captainsim.org/yabb2/YaBB.pl?num=1354222724
Additionally, check Paul's work on the Vref gauge and callouts. http://captainsim.org/yabb2/YaBB.pl?num=1353062742

Thanks CoolP. I will try that out. I'm not enjoying the process of testing different config settings.

I really wish people didn't have to go through all this trouble. Isn't it enough that they tested it, as well as paid for it?

I guess you have a point. From reading, the 0.9 values were fine and the 1.0 ones then incorporated the high power FDE. I don't know about the reason behind it though. Maybe some of the testers can tell. Same as you, I'd wish for a refined FDE in 1.1, getting rid of the 'need' for user mods.

There is one other value that I changed in the [TurbineEngineData] settings. I'm not sure if it makes a difference though.

[TurbineEngineData]
fuel_flow_gain = 0.002                          //Gain on fuel flow
inlet_area = 9.6                               //Square Feet, engine nacelle inlet area //19.6
rated_N2_rpm = 29920                            //RPM, second stage compressor rated value
static_thrust = 17400                        //25000
afterburner_available = 0                       //Afterburner available?
reverser_available = 1                          //Thrust reverser available?
ThrustSpecificFuelConsumption = 0.385             //Thrust specific fuel consumption (Jets)
AfterBurnThrustSpecificFuelConsumption = 0      //TSFC with afterburn/reheat engaged

I remember someone else saying something about the inlet_area being only about 9.6 square feet, so I changed that too. I'm not sure if it makes much difference because I never tested it. I might give it a try so I can see if it does.

@CoolP. I try t keep it relatively close to the original (so I can change them back to help someone if necessary), so I don't install MODS (except for the V-One MOD). Wink

Markoz up your fuel fiow upto .510 as the JT8D likes its fuel alot
There is a reason the NGX can get a lot more miles out of only 13,000 more fuel lol

Not sure I get what you mean there. Undecided

Yesterday, I flew the 737-100 from KSEA to KSFO (~600nm). With the amount of fuel it used to go that distance, I would be worried that it would be very low on fuel by the time I flew it 1540nm, which is the maximum range for the 737-100.

If your running the -100 the thrust should be fairly low around 12000-14000lbs IIRC I'll look it up to be sure

Makes perfect sense, Mark. As stated above, I'm hoping that 1.1 renders the mods and tweaks unnecessary.
