Black Square Steam Gauge Overhaul - King Air 350i

If you don’t like the quality of support provided by everyone here, perhaps you could try your luck doing some more research for yourself, and Google a bit.

You can use high idle on the right engine during engine start, to assist with power while starting the left.

Other than that, mostly low idle is used, except for certain circumstances, like high altitude takeoffs, or takeoffs from short runways, things like that.

Remember that high idle / low idle is just that: idle power. It’s not making any difference in overall engine power. High idle does have influence on spool times: the engine is a little quicker to react to power changes.

@ MojaveHigh2379 hope this will dispel your doubt !
a summary high idle on check list is just for a brief instant, regarding the gas
then fly must be low idle

why so rude ? probably he s a bit tired

don’t pay attention, sometime I would like to go straight like this with some users wondering about each switches or features :innocent:

you are not the most disturbing so far :wink:

What a painstakingly detailed manual. This aircraft will steal the top crown in the “Top 5” thread very soon.

I said nothing about the quality of support in this thread: I continue to learn a lot here. I have just seen some contradictory posts that confused me. Though the one about flying in high idle has apparently been deleted.

And I didn’t see anywhere in the Black Square supplied manual about bringing the condition levers down to low idle after setting them to high for takeoff. Perhaps I missed it. In the future, I’ll be sure to search and read rather than ask questions here.

After flying it a lot in the past 2 days, i can tell you that low-idle (at least during approach) definitely makes more sense, hence the speed slows down “naturally” and not “forcibly”. Apart from what was mentioned above, it looks like it really doesn’t matter much which you use during flight/cruise as it seems it to be up to the pilot.

are u still having a doubt ?
the only one saying flying in idle high as far as I remember was JayDee , he does while monitoring performance ! as it make mod it was just a tip to get accurate number

thought he said also that s not the way to usually fly in cruise altitude :wink:

edit : looking at"N4790G", he also mentionned this but was on a different aircraft

“If I recall, and could be wrong… high-idle is a must for flight, because if/when you pull power to idle (like on short approach), and then need to add power… the spool-up time is less. Not sure if that is modeled…”

then he promptly added :

“My only time as PIC, is light pistons… but I did sit right-seat in C-90… The pilot explained how slow the “throttle response” was, compared to a piston… adding that high-idle, reduced that lag… or that is how I remember it… :thinking:

Deelee6800 said also

"High idle is not required for flight. All low/high idle does is set the min idle speed/RPM for the gas generator. High idle good for - short field since you will get faster spool up selecting reverse, ac on while on the ground (one engine to high idle)… maybe some other cases I am forgetting. That being said, it’s up to the operator. Just know that the condition lever is not a mixture control. It just sets the min idle rpm.

Possibly already discussed or in the manual that I don’t have at hand so apologies.

What is SR on the autopilot panel?
When and why used?

Thanks in advance.

SR soft ride :
"A few systems also include a switch that determines how hard the autopilot will try to hold altitude in turbulence. This kind of switch might be labeled “soft ride” (e.g., King KFC 275 and 325 systems). " (Your Best Friend Or Worst Enemy - Plane & Pilot Magazine)

I’m trying to understand the difference between ALT and ALT SEL on the autopilot. When do you use either?

alt = maintain altitude
alt sel = labelled as “vertical navigation” so must use altitude that are set inside the FPL maybe l m wrong

Another cool feature is the “pitch sync” switch on both yokes. This basically locks whatever airspeed you’re currently at during climb or descent, instead of using the rocker switch to adjust airspeed.

hi I started today some livery conversion : it s my first mod, please don’t be rude if some error are in
:-/ sure I did some

for those that may interest Livery pack » Microsoft Flight Simulator
don’t hesiate to mp me for any feedback
Big thanks to JD for his original work on the analog c208 as it has been a nice model for this one and very helpful

Edit : file ver 1.0 has been approved, includ all livery now !

Here’s a full ( and at two hours, comprehensive! ) review with a King Air pilot & a MEI.

In ALT+HDG mode, after Press APR, the autopilot cannot automatically established the ILS signal.
NAV1 and NAV2 all set ILS feq. and HSI show right signal.
but the AP can’t fly via LOC/GS.

Is the aircraft of this aircraft so backward?

It’s capturing the glide slop for me!
Just gotta make sure you’ve entered the correct ILS frequency, flying at or just below the capture altitude & have selected VOR and not GPS

i ran across an interesting discussion regarding the high idle / low idle question on reddit.

the thing everyone needs to keep in mind is that there is some behavior in the sim (whether it’s with this addon or the base sim, i don’t know) that is not completely correct. when you are in flight at cruise settings, pulling the levers to low idle should not do anything to your torque, etc. that’s not the case - by doing this now, you will see a drop and i don’t believe that’s correct. (edit) there is also a comment about prop drag that is discussed in that thread that we don’t experience in the sim. (end edit)

at the end of the day, this is a sim/game. if you want to run the plane in high idle you can. the supplied checklists don’t tell you to pull the levers back. if you would rather run it in low idle, you can. i think the plane is far more controllable in low idle but there’s a voice in the back of my head telling me this isn’t the right way to do things only because i don’t want to have to worry about pushing those levers forward when i really need them - once you get into that spot there are a lot of other things going on that require attention.

I find it more enjoyable at Low-idle. Just did a low-idle takeoff from Sedona in really bad weather and set it to climb all the way to 30,000 ft using climb mode (all on low-idle) and it didn’t miss a beat. Only had to switch to IAS around 20,000 but that’s what i was also doing previously with High-idle.

old statement about vnav

“then he promptly added”

I didn’t post that… you’re quoting someone else…

maybe give it a try, and before reinstalling check if he s up to date
