Hi @Black-Square,
You might remember me mucking about with the Starship and the DH and MDA vars, getting them exposed so I could show them on a Stream Deck from this thread
Well you'll be thrilled to hear I've been fiddling again - this time with the Bonanza!
I've been building a Stream Deck profile for the aircraft using PilotsDeck, and following the same approach you kindly helped with on the Starship, I've made some small modifications to KAS297B.js that I'd love to see included in a future update, both to save others the effort, and more selfishly, so that my changes don't get overwritten!
The KAS297B has several internal JavaScript properties that are invisible externally, so I've exposed some of them as L-Vars with the following additions:
L:var_kas297b_ArmedVS (feet per minute)
The "pending" vertical speed held in this.armedVerticalSpeed before ENG VS is pressed. Updated in each of the 100_INC, 100_DEC, 1000_INC, 1000_DEC knob cases, and also in the Update() loop where armedVerticalSpeed is synced from the AP var.
L:var_kas297b_OptionalArming (0/1)
Exposes this.optionalArmingMode. Updated in the ArmButton case (both true and false branches), and in the Update() loop where it's reset when VS hold becomes active.
L:var_kas297b_ArmAnnun (0/1)
Mirrors the ARM annunciator state. Set at the end of the ARM annunciator block in Update().
L:var_kas297b_AltAlert (0/1)
Mirrors the ALERT annunciator state. Set in both branches of the altitude alerting block in Update().
L:var_kas297b_CaptAnnun (0/1)
Mirrors the CAPT annunciator state. Set at the end of the capture annunciator block in Update().
All changes are purely additive and don't change any existing logic. The L-Vars only update when the underlying values actually change, so the performance impact should be negligible - they're driven by the same conditionals that already drive the screen annunciators.
I'd be happy to share the full modified file or a diff if that would make it easier.
For reference, here's a summary of all the new L-Vars:
L-Var
Type
Description
L:var_kas297b_ArmedVS
feet per minute
Pending armed VS value before ENG VS is pressed. Matches what the unit displays on screen.
L:var_kas297b_OptionalArming
0/1
Whether optional arming mode is active (ARM button pressed manually).
L:var_kas297b_ArmAnnun
0/1
Mirrors the ARM annunciator on the unit display.
L:var_kas297b_AltAlert
0/1
Mirrors the ALERT annunciator (aircraft within 280–1020ft of selected altitude).
L:var_kas297b_CaptAnnun
0/1
Mirrors the CAPT annunciator.
Thanks again for everything you do for the community - and for being so generous with your time helping users like me dig into the internals... probably a little too much!
Here's an unfinished example of what it's all for, straight from the Stream Deck:
