Advice for CRS,HDG, Altimeter knob Encoder
-
Hi guys, i’m going to upgrade my flight-station… need some advices regarding encoders. I use Pokeys 56U, but what i need to know is, how many pulse-per-round do i need? 12,24… i choosed 12 pulse for ICP thumbwheels ( i know that real ones are pots, but i decided for encoders) and they are very good, but i’m not shure if they can go as good for CRS HSI knob and so on…
thank you!
-
Don’t know if it’s still valid but a long time ago I noted the following rotation on old block 15 instruments
- Mach index: 360° = 50knts
- HSI CRS & HDG: 360° = 35° or 40° (don’t know for sure anymore), don’t know if EHSI is the same
- ADI & altimeter: totaly forgot to test
-
Thanks FD. More than i was thinking! Ok i will check them. Another question… i also need instrument & fuel quantity sel panel knobs. What kind of actuator are them?
-
The fuel qty sel ext fuel trans switch is, IIRC, an F type locking Honeywell 2TL1 (round head, locking types, see attachment).
You sometimes find similar switches on eBay and Viperpits. You could go cheaper and buy regular switches without special locking and add replica caps (like this http://lynx.dk/product/honeywell-2tl1-switch-top-replica/)The fuel qty sel knob is a rotary knob. The real one has a momentary function for the left Test function and is pretty expensive and hard to find. I will use a regular rotary switch without momentary left position. I don’t remember if it’s 30, 35, 40 or 45° anymore, but can be checked based on the panel.
For the knob on top, you can sometimes find runs at Viperpits that make a batch, or find people that have extra and sell them from time to time.
I bought a complete set from Biohazard there.As I will implement the EHSI, I will have a blank panel on the left side and not the NAV/TCN/INS rotary, so I have no info for that. I would assume regular rotary (no momentary functions) where again number of degrees per step can be found by measuring on the panel, and a potentiometer for the instr knob below it.
In attach my fuel qty sel panel.

I have a 1TL1-3D (D lock type) toggle installed in my FUEL QTY SEL panel, but it may be that I should actually have a G…and I have a real F-16 rotary switch for the panel. And acceptable substitute for the rotary switch is a Grayhill 50CD45-01-1-AJN type (45 degree throw, six position), where you can set the stops…but that won’t get you the spring loaded momentary action in the TEST position.
As for the CRS and HDG knobs - I have Martin’s EHSI and it does use encoders - free 360 degree rotation, and probably with 36 (or more) positions; I know it’s seems like a “fine” sort of throw between clicks. His also feature a depress/button action - this is used to take advantage of BMS having callbacks for 1 degree and 5 degree increment/decrement - pressing the knob allows toggle between each. Very nice feature which I’d suggest building and leveraging Pokeys to make work via shift layer.

This really isn’t necessary. If you add to your config this line: set g_nKnobAccelerationDelta 90 // controls fast or slow behavior for mouse wheel or encoders Default 60
Turning your encoder slowly you will get “by 1” behavior and turning it quickly you will get “by 5” behavior. This will also work with key presses, which is how I use it, since I have a CPD, which has buttons. So excerpt from my keyfile is:

…one of the great things about the Pegasus EHSI and DED Capture is that this 1 or 5 degree per increment toggle is a built-in feature - so I’ll be using it! But I like what Badger suggests as well…so question now is, how does the real one work?

IIRC when testing it in the sim, it was 1° only.
There is a push function just like Pegasus EHSI has, but it’s used for other purposes.
When pushing the right CRS knob long enough, a “BRT” label appears in the center of the EHSI, momentary you can then rotate the right knob to increase/decrease LCD brightness intensity.Also nice to know, and IIRC not implemented in Pegasus or BMS version, the EHSI has 2 CRS stored.
1 course is for ILS (PLS) modes (so ILS/TCN & ILS/NAV; 1 for the other modes.
The ILS course is primarily set in the T-ILS page via UFC and is tied to the EHSI. When you then change it on the EHSi, it will also change on the T-ILS on the DED.
When you are in for example NAV mode and set a CRS there, it will be a separate one. Switching back to PLS/NAV via the M button, it will again show the stored ILS CRS. -
just a small precision on the above, it’s valid only for the EHSI, not for block equipped HSI

@Red:

correct! Thanks for clarifying

Switching back to PLS/NAV via the M button, it will again show the stored ILS CRS.Turns out that if you look at page 64 of the DED Capture manual that you can also set up Martin’s EHSI as I describe, or as Badger describes, and also does the short/long press action you describe - I really LOVE DED Capture! I went my way in setting mine up, but I may try Badger’s in the near future. The grey center button is for changing Mode (and I need to stencil an “M” on mine), and worked as such when I plugged it in.
Still…how does the real thing work?
-
What do you mean how does tje real thing work? What I described above is how the real One works.
-
Martin gives us two (three?) options to use in single or combination, so I had to ask for some clarification. I’ve also seen EHSIs from different vendors that behave differently…I need to do some research, I guess.
-
All I know is what I noticed in the BAF official Sim, from talks with pilots ans from the public m3 documentation. Don’t know about differences in other vendor versions
-
That’s fair…I need to do some research and make sure I implement what’s appropriate for what I’m building.
