Black Square Steam Gauge Overhaul - King Air 350i

Any Star Wars fans see anything here…

I dont recall the Stormtroopers have a moustache

So pleased.

Not sure if this will be a massive help but some might find it useful. Since the preview code for the KA was sent out a few weeks ago so much work has gone into the development of the King Air we thought supplying you with a Changelog might be useful. Aware it’s not covering something that most of you originally trialled but I’m sure you’ll have taken much on board from what was reported about that build.

Here’s the Changelog anyway:

v1.0 - Initial Release (Changes from Preview Build)
New Features:

• Possible CTD causing variable noted by forum user Nicotine70 in the Analog Caravan preemptively eliminated in the King Air. A note to other developers: Apparently, MSFS does not play well with the Simulation Variable “WINDSHIELD WIND VELOCITY”. Although it is documented in the SDK, it is not used anywhere in the vanilla codebase. There are several suitable alternatives for this value, such as “RELATIVE WIND VELOCITY BODY Z”.
• Complete Climb and Descent Profile Modes. Descent mode will now continuously increase target indicated airspeed to follow the barber pole. Climb mode will now target the following climb profile: 160kts to 10,000ft, 140kts to 20,000ft, 130kts to 30,000, and 120kts above. Selecting manually changing target airspeed with the rocker switch, or with the CWS yoke-mounted button will exit either profile mode and enter IAS Hold mode.
• New aerodynamics and engine performance configurations contributed by JayDee. Single engine climb performance is improved, as a result. Best single engine climb performance is now achieved at +/-5 kts of the marked blue line speed.
• Battery voltage drop now simulated. Large DC loads will pull down voltage.
• Left/Right/Center bus overhaul and Left/Right/Center bus diodes to the Triple Fed Bus implemented. Battery bus tie controller and battery relay are now properly implemented. Electrical schematics updated to reflect diode placement.
• Airspeed hold mode on autopilot mode controller.. Pressing “IAS” will hold the current airspeed in a climb or descent. Remember that the King Air does not have auto-throttle, so the only method the autopilot has of controlling airspeed is pitch. Holding airspeed can be adjusted via the rocker switch on the mode control panel, as with other modes. Recall also that climb and descent modes are simply managed airspeed hold modes.
• Locking toggle switches animated with locking spring action.
• Radio background materials. Unlit digits and segments are now visible when equipment is off, and vary in appearance with viewing angle. Individual electrical traces are also visible.
Bug Fixes:
• Torque bloom calculations were causing artificially limited torque at high dynamic pressures. This is now fixed, and has improved fuel flow at high altitudes, and single engine climb performance.
• Automatic load shedding on dual generator failure fixed. Bus Tie Man Close switch position for nighttime start will now have the correct effect. Tip: Man Close at night is used to enable all interior and exterior lights, some of which derive power from left and right generator buses. External power will also now close the generator bus ties.
• Battery voltage curve adjusted to better match lead-acid performance, and battery voltage pulled up to bus voltage when connected through battery relay.
• Hot battery bus emergency disconnect switch behavior corrected.
• Battery Bus Tie now disconnects Triple-Fed and Center bus during bus sense test or fault. This allows for full bus isolation in case of a fault.
• Voltage meter needle no longer reads zero for all buses during battery failure.
• Propeller Amps and AC Multimeter continue to read when battery is discharged.
• Inertial separator torque reduction is now applied smoothly as the baffles are moved into position, instead of all at once at the end.
• EXT POWER annunciator now blinks when external power is available, but not on.
• Yoke Chronometer 1’s minute digit fixed when elapsed time is over 10 minutes.
• Ensured the default “Autopilot Engaged” sound will not be heard.
• Connect gyro sound to turn coordinators instead of battery master.
• Interior bounce lighting no longer tied to “GENERAL PANEL” circuit.
• Light potentiometer default values (instead of zeros) load when starting from cold and dark.
• Improved battery emergency disconnect logic.
• CTL32 navigation radio active tuning mode will deactivate after 10 seconds.
• Decision height indicator brightnesses adjusted.
• DME data displays tweaked to eliminate false readings or maximum values when no signal.
• Remote compass controller model corrected so that the needle moves, and not the scale.
• Autofeather performance improved in very cold weather. Previously, autofeather may have disengaged when gas generator RPM was still within acceptable range.
• “CONDITION LEVERS - HIGH IDLE” added to Takeoff (Cleared) checklist to remind users, although this is absent from most actual King Air checklists. The PT6 engine condition lever only adjusts idle gas generator RPM in the real world, also affects the throttle set-point in the simulator.
• Panel integrity lighting missing on some load-shedding indicator rings fixed.
• Manual updated with all new features and screenshots.

thanks for this changelog, useful indeed :wink: ! even for those who were watching all preview youtube & twitch should be happy

Thank you very much for the changelog. Your work is appreciated! :slight_smile:

GTN Gauges (TDS or PMS) not installing. Effectively DOA. This is my experience and what Avsim is reporting

Wow - this thing is AMAZING! Just completed my first flight along my standard test flight (KACY - KPHL) shooting an ILS to 27R. Flies like a thoroughbred! Fast and so stable. So many features to explore and some nice touches like readable numbers on the baro (I hate those tiny dials in VR). A clock so I don’t miss my next meeting. LOL.

I managed to stumble through the use of the AP, though it wanted to turn off/disengage when I hit another button (like APPR or VS). Still managed to capture the GS and land smoothly (getting overrun by live-traffic on approach).

The cockpit is busy, for sure, and you won’t take this plane out for sightseeing. Those huge turboprops and high instrument panel block a lot, but it is wonderful to fly. Well done Black Square!

did you have to do anything extra for the GTN750 to appear on the panel? i cant find where to get it to appear. TYVM for your help!!

right side of copilot’s yoke, there is two switch for avionics change

Brilliant so far

How do I get the gauges to be back lit? I’ve looked at the manual and still seem to have no back lighting even with everything set max brightness on the overhead?

did you push the master white button on the left of lighting rotaries ?

I am literally ray charles, can you please screenshot for the blind folk? thank you!!

Yeah it’s odd, I get the “blue effect” light come on, which I can adjust with the rotary switch but nothing else is illuminated?

i should read better, your instructions were clear…right side of “copilot’s yoke”…proceeds to look to the right side of captains yoke lmao

thank you for the help!!

im also trying to figure this one out, ill report back in a little if i figure it out

So does this mean you must take off with condition levers in high idle? I almost always keep them in low idle unless on the ground starting the second engine.

Also, the electrical system is beautifully done. I just want to check though; is the Gen Ties switch the same thing as bus tie breaker. In auto they’ll close, but manually you can open them…? And does it open all bus ties with the switch in open, or just the generator bus ties? Does this mean that the electrical system in the 350 parallels power from each gen? I ask because when selecting the Voltmeter for the generators, they’ll indicate the same, unless the Gen Ties switch is in open.

isn’t the 1st switch “engine instrument” + “flight instrument” and the gyro
what you are looking for ?

I m not on the sim right now sorry I can’t check, maybe I m wrong

sorry to bug ya, how do you actually turn the screens on though? ive never struggled like this lol

It is tweaked. The manual is free to download in the product page. It describes all of the limitations of the product/sim, and what is modeled, changed, etc.
