BLANK display feature improvement request?

mmerelles

I am trying to take advantage of the new BLANK display feature introduced in 1.3 to turn OFF the displays not in use at different phases of flight as per a Boeing 737.


i.e. for the VERTICAL DISPLAY.


The VERTICAL DISPLAY should be OFF/BLANK any given time that VS mode is not active.


At the present time the BLANK light option allows to validate against the dataref value you use for displaying data on the display. But this is not usefull because the dataref is the data you shown on the display when the display should be active but this dataref does not tell whether the display should be working or not.


Is it possible to add an extra field/dataref option for the BLANK field validate against to validate if the DISPLAY should be ON/OFF?


The dataref that should be shown on the Veritcal Display data is sim/cockpit2/autopilot/vvi_dial_fpm but the dataref the BLANK feature should check against to for deciding to blank the display or not is laminar/B738/autopilot/vs_press. This extra field may be a dataref or a bespoke for more complex verifications like IAS display that goes ON or OFF under more AP mode options

Hope i was able to explain the issue under the current feature implementation.


Maybe the option is there but i missunderstood how to configure?

You need to write a Bespoke Event for the associated display e.g. VS On and VS Off. The events will set a Bespoke Variable which indicates the state of the display visibility by reading the relevant dataref. Your config will read the Bespoke Variables for the BLANK function instead of the dataref.

Alternatively, create a Start event that runs continuously that reads a dataref and sets a Bespoke Variable to the display visibility.

but if a create a bespoke and associate such bespoke to the display, now i can turn it on or off but how do i show data on the display if the field is used by the bespoke?

admin_pps

The logic would be:

Test if display is on (check value of a dataref)
If display is on set Bespoke Var to the value that needs displaying, otherwise set it to -9999999.

In the config, BLANK if the value is -9999999, Light/Disp Data is the Bespoke Var.

I am trying to do exactly this for the FF767. Can someone please write the above post in English for me?

The relevant datarefs are ..
1-sim/comm/AP/vviUP and 1-sim/comm/AP/vviDN
sim/cockpit2/autopilot/vvi_status. Tells you when the system is active. Value is 0 when off and 2 when on. So when this dataref is 2, I want the "Display_VS" on
757Avionics/ap/vs_act. This is the dataref that feeds the Light/Display Data for the "Display_VS". I have this set to blank when equal to 0.

My "Rotary_VS" Clockwise and AntiClockwise control 1-sim/comm/AP/vviUP & 1-sim/comm/AP/vviDN respectively.
As the OP stated, when you reach your altitude, although the vvi_status switches to 0, the vs_act which feeds the display stays where you set it and the display does not blank.

I just can't decode the above post to figure out where to put my bespoke event so that this happens.

Thanks for any help,

I mean, I'll write it a little simpler. Here is my bespoke event called "VVI Display Off"

if sim/cockpit2/autopilot/vvi_status = 0 Next Else NextSkip
757Avionics/ap/vs_act = 0

This bespoke event works and does what I need to do. But what do I assign it to?

OK, Call off the dogs!!!! I've been reading for 2 and a half hours and finally came across the start function mentioned above. Did some playing around and this does work. Always more satisfying when you get it yourself. Great manuals btw. I will stop bothering you

For anyone else out there this is my start bespoke event..

if sim/cockpit2/autopilot/vvi_status = 0 Next Else NextSkip
757Avionics/ap/vs_act = 0
Sleep 20
Goto top
