Mike, nice write up.
Can you comment on SP ops with regards to OEI?
I've heard that you have to do a lot of trimming with each power change with one engine inop. Not like the CJ line?

Comments, thoughts?

Michael,
After you and I talked, I was told that auto trim (like the PC-12) is coming in Feb. Not sure if it’s a software only upgrade (presumably available for existing airframes) or just for the new ones. That should make power changes much easier to manage.

I call first dibs to be MP’s next child. If he gets a PC-24

Shoot, I’ll put in that bid without the qualification.

Brent, thanks for that update. So you are saying that currently the PC24 does not have autotrim when OEI?
Excuse my ignorance, but does it have it have it now when both engines are functioning?

Correct, currently, only rudder bias when OEI. Rudder bias doesn’t take out all the force but assists the pilot with rudder input. Servo only, doesn’t use any trim. Pilot must trim out the force.



Currently, auto trim isn’t available when both engines are running; however, since the thrust is typically symmetrical when AEO, it’s really not needed (like it is in the PC-12).

The new feature, called Automatic Yaw Trim, works like the PC-12. Under normal AEO and YD engaged, it keeps slideslip at zero, ball centered (or trapezoid), using the servo and rudder trim. OEI, automatic trim maintains a 1/2 ball in the direction of the operating engine. Any power changes that impact yaw (typically only when OEI), the automatic yaw trim takes care of for the pilot. I’m hearing it will be out in Feb or so with load 5.

I have very little time in the CJ3/4 and Phenom 300 and I don’t remember any of those having automatic yaw trim (I think both have rudder bias but that still requires pilot input with rudder or trim). Anyone know?

Pilatus has worked out most of the bugs now and starting to release some new features. Windscreen cracking issues are also fixed with going to a new manufacture. Honeywell load 5.0 software will address a lot of the software bugs.

I believe the PC-24 is ideal for the Penman’s. There just isn’t enough room in the CJ3/4 or P300 for you. Sounds like your family is growing from the posts above. Lol.
