January 29, 201016 yr Nick is a pretty good source in his own right. Have learned much from him since he joined the beta team. Dan Downs KCRP
January 29, 201016 yr Hi Paul,My sources are a combination of the Atlantic Coast Airlines J41 Systems Class Supplement, the J41 POH, The J41 QRH, my experiences over ~200hrs in the J41 jumpseat, and my experience dispatching the aircraft for more than year (until they were all retired). I'm certainly not "the" authority...it's been several years since I've even laid eyes on a J41, but I'm not just making stuff up, either.If a start attempt could not be stopped with the CONDITION Lever, there would be no need for the F/O to guard it, and the Latch Release button at the same time during every start. Yet, thats what they do. So even if the documention isn't as unambiguous as it should be, the fact remains, the QRH directs that for abnormalities like a "STARTER - NO CUT-OUT", the start should be aborted with the CONDITION Lever.As I mentioned, I'll try to reproduce the behavior you're seeing, and if I do, I'll make sure it gets reported.
January 29, 201016 yr Just tried this, but in my case it works like described in the AOM and Nick. Pushing the latch and pulling the condition lever aborts the start immediately.
January 30, 201016 yr Hi Paul, Yes, I'm sure. The STOP switches are used for normal shutdowns on the ground. It causes the Air Purge system to operate (causes increase in RPM and FF), and it relies upon electrical microswitches to close the associated fuel valves. The CONDITION lever, on the other hand, will cause an IMMEDIATE shutdown of the engine using MECHANICAL means to ensure that the fuel Manual Shutoff Valve and LP Hydraulic valves are closed, and the prop is feathered. It also performs the same electrical functions of the STOP switch: microswitches close the LH and HP fuel valves, the LP hydraulic valve is commanded close (it should already be closed), the starter is disengaged, and the bleed air valve closes. The CONDITION lever method is used for ALL in-flight shutdowns, and for any abnormal start or operating condition on the ground, such as a hot or hung start, overspeed, unresponsive/runaway prop, etc.Jurgen,In the real world, you can press the LATCH RELEASE buttons, and feather the prop at any time...there is no inhibit. In fact, the proper method of starting the engine involves the F/O putting one hand on the CONDITION lever, and the other hand on the LATCH RELEASE button as he monitors indications during start. The intent is to be in a position to IMMEDIATELY abort the start in case of an abnormality.I have never tried to abort a start using the CONDITION lever in the PMDG bird, though I have used it to successfully perform in-flight shutdowns. Later today, I'll check and see if I can duplicate your issue.Hey Nick,that's the way I expect the handling !also shown here: (two hand method)regardsJ
January 31, 201016 yr I have the same problem. if you dont push the red button down before the start switch is pushed the red button will not move. If you push the red button before the start button is pushed then the condition lever only goes to the maximum positionChris Finlay

January 31, 201016 yr Okay, sorry for the late follow up guys. Real life is such a distraction!I can confirm that I am unable to press the Latch Release buttons after ignition and until starter cutout. I'll report the issue as promised, but I don't want anybody to get their hopes up. It's likely that with everything else going on at PMDG, priorities will not be on immediately correcting this issue. Further, it might very well be that this issue is "by design". There were a lot of tricks that had to be done in order to get the FSX turboprop model working correctly, and it's conceivable that they had to limit interaction with the systems during startup in order to achieve predictable behavior.These are just my guesses. If I get any information from RSR or the team, I'll let you know here.
