B737 300-400-500 (multipack Rikoooo) climb problem

Unread post by CL38 »

Hello
On P3Dv4 with a B737-400 or B737-500 (classic multipack Rikoooo) the plane (with after takeoff activation of the PA, SPEED = 250, ALT = 10000, A / T engaged, V / S = 1800 or 1500) loses too much climbing speed until you get off the hook. I manage to get it up by doing a lot of intermediate levels to make him regain speed.
On FSX, with the B737-800 I do not have the problem, with a V / S = 1500 the plane rises steadily up to 31000 ft.
If anyone can tell me what I'm doing wrong, it will save me time-consuming research.
Thank you

The older 737's did not have the thrust capacity that the 737-800 did. If you go to you're aircraft CFG file, open it and scroll down to {Engine } section, there is a line of code marked thrust.... I do not use this aircraft but lets say the thrust is showing 18929, add about 4000 more pounds of thrust so it reads 22929. That should allow to clime at 1800 fpm Here is an example or the section you would be looking for :
[TurbineEngineData]
fuel_flow_gain = 0.002 //Gain on fuel flow
inlet_area = 19.6 //Square Feet, engine nacelle inlet area
rated_N2_rpm = 29920 //RPM, second stage compressor rated value
static_thrust = 28000
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

Thank you for the answer; I tested 28000 and it's OK.
