Evening all -Loving the JS41 - still the number 1 plane in my hangar at the moment. Just to make sure I am not missing the boat I have a few quick questions. Yes or no answer are fine - I will dig up the rest of the information.1) Is it possible to start the JS41 engines without ground air / power?2) Is it possible to restart an engine after flame out or is restart of FSX required to clear configuration. This is a rare instance but it happened last night when an inadvertent key press caused the throttles to advance while I was setting a EZCA camera. Burned up right at the gate. I waited until EGY dropped to sub 200c but it was still a no go.3) Missing navadat (latest cycle) for TPs at PASI / KORS / CYXT. Does anyone have the approaches at these airfield in their FMS? I thought I had them once before. If you do have them what navdata are you using?ThanksBenjamin Van Eps

1. I think it is possible using the battery to start the engines. Make sure you have enough battery power first. I think the procedure is mentioned in at least the tutorial. See page 352 of the AOM - Ground Engine Starting - Internal Power.2. If the engine caught fire, you are S.O.L. You won't be able to restart it. It is destroyed. I haven't found a procedure so I don't know if you can restart it.3. I'm using 1201. I don't have the STARs for PASI and nothing for KORS or CYXT. Perhaps PASI dosen't have stars and Navigraph just doesn't have data for KORS and CYXT.

I've never been able to start without the cart. One engine, think it was number one will startup until the cutout phase and then just dies. no fire, no damage, just spools down. Add ground power and she start perfectly everytime. FRED

1) Nailed it. I had two things wrong - I think the avionics were left on and they were drawing too many amps... and the biggest issues, I didn't have the GEN swtich on.2) I think you are right - when it's gone it's gone. No need to extinguish fire and wait for EGT to drop. ATC was just waiting and waiting...and wainting while ground crew was fanning the engine.3) Ok, I didn't see any approaches or STARs for any of them (don't think there are any stars for any of them...) it was more approaches I was looking for. It's no problem, the waypoints are in the database so I will just drop them in. Since the XLS isn't certified for approached any way, no biggie.Thanks for your quick response, Kenny.

Make sure that you turn the engine generator on before you start the engine. That way there will be electrical power to the aircraft automatically before the cutout phase.

Not particularly sure regarding the J41. But in some smaller Garrett aircraft I'm familiar with it is a big no-no to try and start the second engine with the first engine gen operating. Draws far too much amperage and will zap your brushes and melt your armature pretty quick. It is acceptable to run the gen though to give a quick top up (30 secs to a min), then disconnecting it, and preceding with the second start. This get a little wonky with older 331 equipped aircraft with manually selected series starts and all that fun. Of course, avionics, inverters etc should be all off.

Yeah, the AOM is pretty brief in the description.If I understand it correctly:1) BATTs - ON2) START MASTER3) GEN 1 - ON4) START LEFTOnce Engine 1 is started, start Engine 2 - then turn on 2nd generator.See Chapter 8.5 Page 22 of the AOM.

Awesome post. Thanks for that.

Id say your props are in the feathered position when you startThe battery simply doesnts produce enough power to get them startedUnfeather your props and you should have no problems starting them with the battery.

Agreed - it's no problem now that I have the throttles unfeathered and locked + throttle position correct. They start up just fine now. The EGT cooling for restart works like a champ as well on the manual start mode (engine computers off). EGT drops like a rock. Thanks for the help guys.Bman.

In 1202: PASI has two SIDs, no STARS (should have 3 approaches); KORS is not present (should have one RNAV approach to the airport); CYXT is not present and I have no data for it. There you have it.DJ

1) Is it possible to start the JS41 engines without ground air / power?

I almost always start without the use of ground power, so it's perfectly possible. As far as I'm aware there is no difference in the start procedure; for any start you need all anti-icing and avionic systems off, boost pumps on and propellors set to fully fine pitch. To be honest, I'm not really that familiar with the start procedure using ground power, do you disconnect the cart after engine 1 is started?

Make sure that you turn the engine generator on before you start the engine. That way there will be electrical power to the aircraft automatically before the cutout phase.

I don't turn the generators on until after start is complete and I have no problems.

2) Is it possible to restart an engine after flame out or is restart of FSX required to clear configuration.

Yes, simply go in to the FSX Failures menu and hit "Reset Failures". This will clear the Engine Failure and allow you start the engines as normal (but make sure your EGT is below 200'c first!)
