I was looking through the CRJ-700's Aircraft cfg file and noticed a line saying "Min_Throttle_Limit=-0.25" I started up flight sim got in a CRJ and engaged reverse thrust. The maximum amount of reverse thrust I could get was 25%. I went back and chenged the line mentioned above to read "Min_Throttle_Limit=-0.75" then I went back and tried reverse thrust in the CRJ. What do you know, I could get up to 75% reverse thurst by holding down F2. :D I tried changeing it to read "Min_Throttle_Limit=-1.00" and got 100% reverse thrust but after I finished backing up the plane I idled the throttle and hit the brakes. The momentum made the plane tip back onto it's tail so I recommend 75% but you can expieriment and see what your preference is. By the way the "Min_Throttle_Limits=-0.25%" is under the [GeneralEngineData] section of the aircraft cfg file. Some of you out there probably already knew about the stuff mentioned above but there are still those of us who hadden't yet figured it out.

Hmm...is possible to actually fly the bird on the reversers? Got to test it. Nah, didn't work. The aircraft started to turn around after a while. Thanks for the info.Ulf B

I remember asking some Canadian Air Force pilots about the thrust reversers on their cargo planes. I was looking for information relating specifically to the militarized A320 transport, the CC-150 Polaris, but didn't get what I was looking for at that time.Amyway, the pilots told me that in war zones where tug carts are in short supply, it's a common enough practise for the cargo planes to use thrust reversers to back themselves up. That, and I've heard second-hand stories of airplane spotters who have seen commercial jetliners use reverse thrust to back away from the gate at civilian airports. Those who adhere to the philosophy of "An Inconvenient Truth" would probably not be impressed.In any case, there's no real penalty for abusing the thrust reversers in FSX, however, there are some models I recall from FS9 that would have tip-over problems if you did it wrong. You can try adjusting the values in the .cfg (tricky), or you can make sure your fuel and cargo loads are balanced -- some models can get tail heavy and need extra balancing if you are running with a full load. At least, that was my own experience.Jeff ShylukAvsim Product Reviewer

I can verify that sometimes commericial planes back out with their thrust reversers. One time I was riding a Northwest DC-9 at Detroit and the pilot simply used the thrust reversers to back away from the gate.

What should be more or less realistic value of the reverse for CRJ-700 judging by how it works in FSX?Thanks.

DC9 and MD80 can powerback from the gate- It was SOP for Eastern back when. I've seen AA do it in Boston some years back as well. Was on EAL DC9's in 1990 that did it. Probably not common now due to safety issues. the reversing pilot cannot see where they are going.C130's and C17's do it all the time. Heck, a C130 can even start an engine from another's propwash (buddy start) if needed.The jets with high bypass engines tend not to powerback- generally prohibited :)Too much risk of FOD with the intakes being so close to the ground, and the direction that the cascade vanes reverse the thrust.Tim

Had the same experience, same airline, same aircraft, same airport. Prolly different day and gate though! :-hahCheers, :-beerchugEtienne :-wave

FOD = Foreign Object Debris or Foreign Object Damage. Junk on the ground, typically, but really anything that can get sucked into the intake of an engine, or anything that isn't an airplane that strikes an aircraft in motion. Perhaps the most infamous recent FOD was the piece of DC-10 on the runway that felled the final Concorde flight, Air France 4590. FOD is a very serious issue for pilots and aircraft designers as anything that strikes the aircraft can seriously reduce its structural or operational integrity. At the least, FOD cuses expensive damege, and at worst it will kill. One estimate suggests, notwithstanding human costs, that the entire global aircraft industry spends around $4 billion USD a year on dealing with FOD-related issues. Fortunately, MSFS doesn't actively simulate FOD, in fact, you can make your aircraft indestructible. You can use programmed or random Failiures to simulate FOD, though. You can read about efforts to FOD-proof aircraft, which include the extremely exotic "Chicken Cannon". The so-called "Rooster Booster" fires humanely-killed real chickens at test aircraft to simulate a strike from a large bird, something which can cause an aircraft to crash if the bird hits a vital spot, such as happened to unshielded hydraulic lines on a B1-A bomber that flew into a flock of geese. The most modern bird strike investigators no longer require ammunition made from chickens, and instead rely on special-effects-style gelatine-molded artificial birds and computer simulations. Here's a link to a FOD-buster website that has an article on chicken cannons: http://www.fodnews.com/duck_site.htmlJeff ShylukAvsim Product Reviewer

I tried it at -1.00 but when I idled after using it and hit the brakes the momentum caused it to tip onto it's tail so I changed it to read -0.75. I am pretty happy with that level and it still allows you to back up usig reverse thrust.

>Sorry Tim, what does FOD mean? *:-*>FOD is when a man gets sucked into the itake when throttling up. http://www.youtube.com/watch?v=CTWnrXY-aPsDon't worry, he survived.

In my experiences reverse thrust seems louder inside and outside the aircraft.Anyone know how to change the volumes?
