Lear 35A Autopilot question.

Featured Replies

Wow, interesting thoughts....   SPD until F290@GS 250,  then VS.....  Uff  i bet i will practice that.  I have gone into dangerous speed lost during rocket climb sometimes... :P

 

 

About Change in attitude, this is what i do from a leveled steady cruise:

 

1- Change the altitude setpoint and then dissengage hold altitude button

2- Trim the aircraft to desired VSI config

3- Press Alt Selt when VSI starts to move down...

4- Press VS when achieve a stable VSI indication using trim....

 

 

Is that ok that way

BTW, the GS buton is not controlling the speed at all.... keeps green/yellow lighting....   I can only use VS for climbing... :fool:

The "GS" button on the AFCS you refer to means "glide slope" as in ILS. If you are doing an ILS approach for landing you arm "NAV" for the localizer, and "GS" to capture the glide slope. It has nothing to do with speed.

Ohh thanks,   Gee,  i though it was NAV for both.....    Well, i got another one....

 

About the speed button, i though that i could maintain speed somehow.....   Is there any autopilot function to climb as you explained in another thread?

You can using the SPD mode on the AFCS.Have the altitude you are climbing to set and the arm Alt/Sel button.Establish the airspeed you wish to climb at and when it is stable at that speed push the SPD button.If the autopilot is engaged it will now adjust pitch attitude to hold the airspeed in the climb.The SPD mode is similar to V/S in that both modes function by adjusting the aircraft pitch attitude using flight director guidance which tells the autopilot to affect a change in pitch attitude to maintain what ever value is referenced. I use SPD for climbs and then transition to pitch mode at around 500 fpm

for altitude capture.For descent set and select ALT/SEL, initiate the desired descent rate using pitch mode and select V/S when it is established. 

 

Obviously you are controlling the engine thrust in climb, cruise and descent to achieve performance desired.The 800 ITT setting I mentioned is for real world, this is a sim with code and it is not going reflect real world numbers, use what ever thrust setting you need for performance. If you do a little online research there are Learjet pilot training guides on maneuvers, approach procedures etc. as in " how to fly it" The FSW manual does adequate job of explaining what functions are in the sim and what they are for.

All Right!.... I will test it.  I just downloaded the 1.8.   Will try it, thanks...  :-)

Just to share... VS Button for VSI control and SPD Button for IAS Control, all during climb is just working excellent  :dance:    Thanks for the advise.
