August 6, 200916 yr Guys just watched a video on you tube, and did i see right that this aircraft can reverse on its on power?? How is this so?? First time iv seen something like this on a prop, iv seen a dash 8 prop so why doesnt this reverse its self?? Im a jet person, but im being pushed over to the prop side, it seems to give a better feel to flying!!!Danny!!!
August 6, 200916 yr Like the Dash 8, and most other turboprops, the blade pitch is controllable all the way from feather to reverse. Nearly any jet with thrust reversers, and any prop with reverse thrust would be technically ABLE to back itself up under its own power, subject to things like gross weight, slope, etc.The real question is: Is it AUTHORIZED?At ACA, doing a "powerback" in the J-41 was not authorized.Sometimes the manufacturer explicitly prohibits the practice. Other times, it's left up to the operators to decide if they want to accept the risk. I'm not sure which case the J41 falls under. You can always dig up the TCDS and take a peak for yourself to see if it's expressly prohibited by the manufacturer or by the appropriate governing body (FAA/JAA, etc.)Nick

Backing using beta is authorized by the aircraft manufacturer, but my company was more restrictive and prohibited the use of reverse for backing. - the reason being in certain situations (like stepping on the brakes to stop after backing) if you did it too abruptly, the brakes worked fine, and stopped you, but your momentum tipped you back onto your main gear and stood the aircraft up on it's tail with the nose and nosewheel pointed up into the air.At that point after you and your FO stopped the profuse profanity, shut down the aircraft and manage to climb out, it's off for your pee test on your way to the CP's office for office hours - do not pass go, hand in your flight crew badge, manuals, and charts - go home to find the letter of investigation from the FAA waiting in your mail.So to stop while backing - don't use the brakes - take it out of beta, and add power - then the brakes (<--- it's all theoretical knowledge ;) ;) since backing was prohibited by the company.)Steve W.
August 6, 200916 yr Few years ago (as passenger) i was on an Embraer 110 and the pilot used reverse thrust to go back. Lmaire Real Deraps
August 7, 200916 yr the reason being in certain situations (like stepping on the brakes to stop after backing) if you did it too abruptly, the brakes worked fine, and stopped you, but your momentum tipped you back onto your main gear and stood the aircraft up on it's tail with the nose and nosewheel pointed up into the air.Wonder if this happens with the J41 too. A beta tester who is in for a little joke....?
August 7, 200916 yr I think the MD80/90 series can do powered pushbacks too. Think you need to be wary about not stopping too fast since you can "pop a wheelie". Matthew S
August 7, 200916 yr The C130 can do it, too...The Blue Angels' "Fat Albert" does it during airshows.Aside from the possibility of a tailstand, the biggest issue is collision avoidance. No rear view mirrors. :(Incidentally, the PMDG J41 backs rather nicely. And no, I have not done a tailstand with it. Yet.

August 7, 200916 yr C130's at Tan Son Nhut AB (Viet Nam) always backed themselves out of the revetments they parked in... I can't remember what the C123's did. But my barracks was right across the street from the "in-country" terminal and I learned to sleep to the sound of the Herc's.Anyway, haven't done a tailstand either in the J41. Dan Downs KCRP
August 8, 200916 yr Pretty must any plane can/should be able to power back, even the MD11 and A320s, the reason why its authorized on tail engined planes and not on wing engined planes is the risk of FOD damaging the engines.

August 10, 200916 yr Commercial Member Incidentally, the PMDG J41 backs rather nicely.Great! Most aircraft in FS have a problem with reversing. The physics model just couldn't cope.Best regards,Robin.
