Any questions?

[dmbusmc]

Hey, I love the X you created, but I was just wondering if there was any way to fix the oscillations during cruise on autopilot?

[Alejandro]

I'll release a newer and improved version of the Citation X soon, I didn't make the flight Dynamics of the Citation X ,mean while , your are going to have to play with the Aircraft.cfg around this area

Great, thank you for the fast response. I'm not too savvy with messing with the .cfg, but I'll give it a shot. Otherwise, I look forward to the new update. Off subject, the new MD-83 is fantastic, especially with the FMC, great work! Keep it coming!

[Alejandro]

made a back up of th original Citation X aircraft.cfg and copy the one from the learjet45 Aircraft.cfg ,then tell me please

That's why I'm here for my friend

[dmbusmc]

Ok, so I deleted the section you showed from the X and replaced it with the same section from the Lear 45, but it didn't work. But, I found something that did. I replaced the [autopilot] section in the X's aircraft.cfg with the [autopilot] section of the Lear 45's .cfg. It cured the oscillations but two other issues arose after. With the Lear 45's [autopilot] section in the X, the autothrottle works but you can't switch it off, and a caution is always present. Furthermore, you can only change the altitude in increments of 1,000 feet, instead of 100's. I'll paste what I switched below, and maybe you can point out where the issues lie.

This is the X's .cfg

[autopilot]
autopilot_available=1
flight_director_available=1
default_vertical_speed=1800
autothrottle_available=1
autothrottle_arming_required=1
autothrottle_max_rpm = 90
autothrottle_takeoff_ga=1
pitch_takeoff_ga = 8;
max_pitch=10.0
max_pitch_acceleration=1.0
max_pitch_velocity_lo_alt=2.0
max_pitch_velocity_hi_alt=1.5
max_pitch_velocity_lo_alt_breakpoint=20000.0
max_pitch_velocity_hi_alt_breakpoint=28000.0
max_bank=30,25,20,15,10
max_bank_acceleration=1.8
max_bank_velocity=3.00
max_throttle_rate=0.10
nav_proportional_control=12.00
nav_integrator_control=0.25
nav_derivative_control=0.00
nav_integrator_boundary=2.50
nav_derivative_boundary=0.00
gs_proportional_control=25.0
gs_integrator_control=0.53
gs_derivative_control=0.00
gs_integrator_boundary=0.70
gs_derivative_boundary=0.00
yaw_damper_gain = 1.0

and I replaced it with this, the Lear 45's .cfg

[autopilot]
autopilot_available= 1
flight_director_available= 1
default_vertical_speed= 1800.0
autothrottle_available= 1
autothrottle_arming_required= 0
autothrottle_max_rpm = 90
autothrottle_takeoff_ga= 0
pitch_takeoff_ga = 8;
max_pitch=10.0
max_pitch_acceleration=1.0
max_pitch_velocity_lo_alt=2.0
max_pitch_velocity_hi_alt=1.5
max_pitch_velocity_lo_alt_breakpoint=20000.0
max_pitch_velocity_hi_alt_breakpoint=28000.0
max_bank=27,14
max_bank_acceleration=1.8
max_bank_velocity=3.00
max_throttle_rate=0.10
nav_proportional_control=11.00
nav_integrator_control=0.20
nav_derivative_control=0.00
nav_integrator_boundary=2.50
nav_derivative_boundary=0.00
gs_proportional_control=9.52
gs_integrator_control=0.26
gs_derivative_control=0.00
gs_integrator_boundary=0.70
gs_derivative_boundary=0.00
yaw_damper_gain = 1.0

[Alejandro]

you can point out where the issues lie.

I don't know , the sum of all these parameter gives the flight dinamics
as I told you before I didn't make the flight dynamics .

In a future release and update, I will take care of this one, right now I'm supporting the recent release of the md 83 ,I don't even have the Citation x on my machine , what I told you was to change the entire aircraft.cfg leaving only these parts

Ill use the md 83 as and example

I can't get into that plane right now ,But you are not the first to acknowledge this issue
