J41 Reverse thrust

Featured Replies

Hi All.I've been busily trying to get to know how to operate this beast. Much more involved than the usual fare. :( Has anybody gotten their throttle quadrant to put the power levers into reverse? I have FSUIPC, and have calibrated the throttles for reverse, but they will only go into the ground start/idle position. I still have to use the F2 key for reverse. Any ideas on what I'm doing wrong?Thanks in advance.JerryT

Your not doing anything wrong, that's all it will do unfortunately. There is another thread floating around here with some great ideas to map the F2 button, but unable to locate it atm to link it for ya.

I've got Saitek's throttle quadrant and I mapped Button 21 (the black lever's "button" feature) to Throttle decrease quickly - F2-.Make sure that you have the Repeat slider all the way to the right, that way, once you engage the reverse thrust via the throttle quadrant, the button will continuously be pressed.

Doh! Thanks, I'll search for it.

Jerry,What TQ are you using? With my CH TQ, I'm able to get enough into reverse that I get adequate braking on the landing roll, but not enough to come off the start latches. Pretty sure the only solution for the Saitek is to map one throttle to F2.

GuysIf I'm getting the green beta lights to come on does that mean I'm at reverse? Or start locks unlocked? Or both? I finally got a good engine start, taxi checks, and rolled onto the runway, conditioners advanced to 100% rpm, slowly advanced throttles, started rolling then poof up in flames on both engines...that was yesterday..I haven't done a reattack yet. I did a recalibration of my CH Throttle (F16 Style) and modified settings in FSUIPC. So now when I pull the throttle back to idle stop...I get beta lights. Not sure if that's correct or not.I'm almost too impressed with the realism :( Remember there's 4 hands in the real bird making it happen. I wouldn't mind an intermediate option, that allowed the PNF (FO) to manage engine start and engine tweaking throughout flight. Certainly gives me an insight and appreciation into the crews that flew the 41. Earning 121 the old fashion way!Rich Perry

Rich,When the beta lights are lit (Without reverse showing) all that means is that there is enough pressure zto move the props into beta. You aren't actually getting reverse thrust until the reverse lights show up. Maybe someone with more knowledge about it than me will fill us in, but that's how I understand things.If you burned the engines up on takeoff, I'm guessing you pushed the throttles forward too quickly, make sure you watch your EGT and make sure you don't exceed the limits. I know it all seems pretty complicated at first, but once you figure it all out, you won't have many problems unless you forget your in the J41 and stop paying quite as much attention as you should.EDIT: One more thing, you really have to pay attention to your EGT on takeoff on a hot day. I burned many an engine up departing KIAD during the beta process.

If you apply full power while condition is in taxi you will have roasted engines everytime. Be sure to press the take off test button as a last item check before takeoff.

Same as you have Kurt. I do notice now that after calibrating through FSU, I also get the reverse lights to come on now, just not full reverse.Course, if I can figure how to get this thing slowed down enough to not float halfway down the runway, that should be enough. :(

Jerry,If you hit your airspeed targets, you'll do fine with the amount of reverse you've got, then. The key is to "slow down before you go down".

The BETA LIGHTS only mean that oil pressure is being supplied through the BETA TUBE and the propeller is operating in BETA mode. In our all of our TPE331 aircraft at my old company, the call was to be made upon landing "2 Lights" to indicate the BETA LIGHTS have come on, and both propellers are ready for movement of the power lever aft of flight idle.A common misconception is that BETA only means reverse. BETA actually means the range of operation where through the propeller governing system, the POWER LEVER directly controls the blade angle of the propeller.In the TPE331 oil pressure drives the propeller to a FINE pitch (as can be seen if one doesn't engage the infamous START LOCKS - the return spring forces the propeller to feather). Through a set of special set of linkages which includes the BETA CAM on the power lever, the power lever is set to regulate the oil flow to the propeller to move the blade angle. The governors job at this point is to provide high-pressure oil through the integral oil pump.Once operating in Propeller Governing Mode (sometimes referred to as ALPHA RANGE), the Beta Tube and Propeller Angle Control act as a Hydro-Mechanical Pitch Stop, preventing the propeller from decreasing below the minimum propeller blade angle.On the Jetstream 41, the propeller operates between +10 deg and +79.7 deg in Propeller Governing Mode. In BETA Mode It operates from Below +10 to max reverse at -15. I could not find a number for the J41, but in the J31, the START LOCKS are at +9 deg.
