ProLine 21 - PFD

Post by N0L3R » Sat Nov 05, 2016 7:47 pm

Dear all,

Is there anybody here who is somewhat familiar with the Proline 21, specifically PFD Operation?

I need some info regarding the Pitch Up/Down Chevrons and the Horizon Line Movement when the aircraft is in an unusually high/low pitch attitude.

Do you know how these behave exactly?

It would help a lot to have this info to make the PL21 PFD as accurate as possible.

Thanks in advance and Regards !

If you are talking about declutter mode then the info is in the Rockwell Collins Pro Line 21 Base Manual, revision 1 starting on page 22-59.

Hello Ken !

Thanks for your help but I'm searching for something more specific like chevrons movement and horizon line during excess pitch up/down

Are you asking the red chevrons in an PFD unusual attitude? They should display +30/-20 in pitch. I'm referencing Rev 4 of the King Air PL21 w/ IFIS.

Again I suggest you read Rockwell Collins manual 523-0807239 Pro Line 21 Base Manual revision 1 page 22-59 to 22-62. It should describe most of what you are looking for and has an image of the red chevrons. The information Dustoff gave is a very small part of the answer you seek. Due to copyright I cannot copy and paste the entire information here as it is many pages.

Here is the image from the document.

Dear All,

I am following the Manual in all my steps.

I also know that it is a +30/-20 when they appear.

The problem that I have is their behaviour, ergo:

When they appear, do they stay at the very top/bottom of the attitude indicator or do they continue to move in pitch alongside the pitch ladder?
What is meant by 'slide out'?
What is meant by 'scale expands to +/- 90 degrees?

This is the kind of stuff I'm looking for.

Thanks for your help, please keep supplying the info.

I am working the legacy King Airs right now so I don't know when I will have a chance to get back into a PL21 sim.

I'm not due for a recurrent sim until early 2017, but I keep thread in mind.

PM sent with a link to the video.

Update: Since you failed to respond to my PM I can only assume that you are no longer interested. I have deleted my PM and removed the video. I am not going to leave this stuff up forever...

If you want to get in touch with me, members of the development team have my e-mail address.
