Sme Questions and/or Colmments

[louross]

Well, internet here is back up again, so here are my questions for the moment.

1) The checklist says to select Auxiliary on the Start Manifold, but later (After Start ) it says to select Auxiliary- again. So- is Auxiliary always selected? Why the difference- I think it's Auxiliary and Main.

2) Continuous Ignition- should this actually be selected just before take-off and again when descending at 10,000 msl. Isn't that more common? Does excessive use of Cont. Ign burn the plugs?

3) Why does the checklist call for anti-ice for the outboard engines- only? What about the inboards?

4) The checklist says to engage auto-pilot ASAP just after takeoff. Why? Wouldn't climb to 10,000 (on climb, and descent)be more "normal" back when the 8s were flown?

5) Why do all the more complicated programed a/c say to shut off the engine in the default C172, but "touch nothing else"? For example,what happens if I turn off the battery switch?

I hope you answer these questions. as they are real- to me, even tho I have work arounds except for number 1 and 8- second part.

Thanks,
Lou

What aircraft type and panel are we talking about here ....for starters ?


THE REST OF YOUR QUESTIONS I CAN ANSWER BECAUSE THEY'RE OF A GENERAL NATURE

The checklist says to engage auto-pilot ASAP just after takeoff. Why?

That's simply for "FS convenience" .... to the extent a lot is happening (for some people) after T/O. Most people only have 2 hands (where-as there's between 4 and 6 of these on the flightdeck of real world operation) .... so .... engaging the AP early simply enables people to stabilize their simulation "early" .... in the initial post T/O climb stage .... whilst they attend to the other necessities and without risking loosing control of their simulation. That's "the only reason" for this particular recommendation, but, it doesn't have to be adhered ti

Why do all the more complicated programmed a/c say to shut off the engine in the default C172, but "touch nothing else"?

That's only a part of the recommended engine startup procedures .... and there's 3 parts to this recommendation

1. Starting with the default CESSNA (or other default MSFS supplied aircraft type) simply ensures the default FS flight settings/scenario is loaded with any simulation/flying session. It's not essential, but, is "recommended". It should also be done "mandatorily" when changing from one add-on aircraft/simulation to another within the same FS session .... and for the very same reason too.

2. Establishing the CESSNA (or other default MSFS supplied aircraft type) in an engine "OFF" .... prior to selecting/loading ones add-on aircraft of choice .... simply ensures the engines are indeed "OFF/SHUTDOWN" when ones add-on aircraft of choice is loaded into FS. Again .... this's not essential, but, is "recommended" .... esprecially if one intends performing a full engine startup procedure .... otherwise this instruction can obviously be dispensed with.

3. Touching/Adjusting "NOTHING" after establishing the default CESSNA (or other default MSFS supplied aircraft type) in and engines "OFF" panel scenario .... and prior to selecting/loading ones add-on aircraft of choice .... simply ensures the panel for any add-on aircraft of choice is then loaded into FS in it's otherwise default state in order to enable full engine startups with ease. "IF" any panel instrumentation is adjusted within the default scenario .... then these adjustments will be transitioned "automatically" to the panel of one's add-on aircraft of choice when it loads into FS. It's always best to start "as clean as possible" .... especially if a full engine startup procedure is intended.

Hi:

The selection of default C 172 is not only good advice for the HJG DC-8, its also standart advice for other complicated simulations. Another good advice is not to change between full panel view and a windows-window back and forth to avoid crashs to desktop.

"Engage AP just after takeoff" Normal procedures in real and simulated flying are adding: "beeing in a stable flying condition" means: gear, flaps stowed, stable climb, not turning and not beeing in the middle of an after takeoff upheavel. Most procedures prescribe reaching a minimum flying altitude also.

Kind regards

Walter

Okay, and _Thanks!

Am using the DC8-71 series with thenon INS panel- Emory Air Freight Livery.
Thanks,

OK .... now we know you're talking about the DC-8 panels I can respond to your first 3 questions .... as follows ....

The checklist says to select Auxiliary on the Start Manifold, but later (After Start ) it says to select Auxiliary- again. So- is Auxiliary always selected?

The first reference stating set the STARTER ARM switch to "AUX" .... for engines startup .... is correct. The second reference should have stated set the STARTER ARM switch "OFF" .... after engines startup. Just a minor text typo .... now edited.

Continuous Ignition- should this actually be selected just before take-off and again when descending at 10,000 msl. Isn't that more common? Does excessive use of Cont. Ign burn the plugs?

It doesn't matter using these DC-8 simulations/panels .... despite the switch is represented there's no plugs to risk burning out Therefore engage/disengage "CONTINUOUS IGNITION" .... at your discretion. And "YES" .... I'd be inclined to engage this system "prior to" T/O .... and also below 10.000 FT .... as required. Forgetting to engage/disengage this system isn't going to adversely impact the simulation .... at all. Although it's a functional switch it doesn't interact with any other feature within represented any these DC-8 simulations/panels .... unlike may be the case in some of our other panels.

Why does the checklist call for anti-ice for the outboard engines- only? What about the inboards?

The checklist actually calls for "2X (two ...or both) ENGINE ANT-ICE switches to be selected ON" .... as required. One of these 2 switches is for the inboard engines and the other is for the outboard engines .... SO .... upon selecting both switches "ON" .... both the inboard and outboard engine anti-ice systems are engaged. The "OUTBOARD" reference within the tutorial text should have been accompanied by the word "INBOARD" .... which was accidentally omitted. Just another minor text typo .... now edited also.

Okay- I appreciate all these responses. Thanks a bunch!
