Anyone flying the Carenado C-340, is there something about getting the autopilot to descend w/out having to hit the ALT button several times and (2) I assume that there is no alt preset w/ this autopilot. I have never seen this before w/ a GA acrft. Wish there was a more in depth manual for us new to GA and this type of acrft. Thanx for any input.

The Autopilot in the original aircraft has no altitude pre-select function. You need to fly to the level you want, and then hit the ALT button on the AP panel.

 

This requires a minimal change in planemaker. Make a backup of the acf file before.

 

1. Open the aircraft in plane maker

2. Go to Standard - Systems - General 1 

3. Uncheck the "altitude pre-select is always armed" checkmark

4. Save

 

Than the AP works how the modeled system and equals real behavior. 

 

You also may be interested in other modifications regarding the Fuel System of the aircraft http://forums.x-plane.org/index.php?showtopic=74275

This modification represents the real system in regard of refilling main tanks, when aux tanks are selected. 

 

If you like to upgrade the engine to the 310hp power version (modeled is the 285hp version), you can do following as well

 

1. Open the aircraft in plane maker

2. Go to Standard - Engine Specs - Descpription

3. Change "maximum allowable power" to 0,310

4. Change "hi idle adjust" to 0,80

5. Change "lo idle adjust" to 0,80

6. Save

 

This changes had been verified by a real C340 pilot. The aircraft has now a bit more power, and taxiing on ground is better now.
