I downloaded Autotrim from FS Freeware.com and I cannot understand the instructions. Anyone have success installing this and what do you think?

Phooey!

I've never heard of it. What exactly is it supposed to do?Willhttp://www.precisionmanuals.com/images/forum/ng_driver.jpg

I am at work now. I am trying to think of where I got it. I think it is supposed to autotrim the plane when the flaps are put down or up at least. The instructions are in broken english and I cannot figure out how to install it. FS2002 FS2004 Autotrim GaugesThese transparent gauges strengthen the effect of the elevator by continuously setting the elevator trim axis to a percentage of the actual elevator axis position. This percentage is dependant on the flaps position, since more additional trim is needed for higher extended flaps, to give good elevator control over the whole flight envelope. When the gauge de-activates, it sets the trim to neutral. Obviously, when the gauge is active, user trim commands are ineffective since they are immediately corrected. The gauge (i.e. trim control) is only active when the autopilot AltHold is off (to allow the AP to control trim). The gauge activates when main panel is shown and then stays active at all times no matter what vew of the aircraft you have. By Alejandro Villa. Public Domain. 12,6 mb

Hey guys I have been using this gauge and it isnt perfect but it works fairly well. It automatically adjusts pitch to maintain the attitude that the aircraft is at. I have been using it when flying airbus's as this is how the autotrim works on that aircraft. Also I turn the pitch stability in the flight tuning section of the aircraft.cfg up a bit.......this seems to help Russ.............

I guess you are referring to file "autotri2.zip" , from Alejandro Vilas ??If so, maybe I can shed some light on this, although I'm a bit puzzled as to why Alejandro wanted to release this as a generic gauge.The gauge does exactly do what is described in the Readme: it continuously sets the elevator trim to a (flapsposition-dependant) percentage of the current Elevator position.When is this gauge usefull ??For aircraft that can fly at extremely low speeds (e.g 10 - 20 knots IAS, like a Harrier). At these low speeds, the elevator is almost ineffective if applied with normal effectivity; and increasing the elevator effectivity (in the aircraft.cfg) to the extend where it is effective at very low speeds, makes the aircraft way too sensitive for elevator movements at normal (cruise) speeds. So at these very low speeds (with full or nearly full flaps) the gauge lets the elevator TRIM automatically follow the elevator position. And if you couple that to a very high value of elevator trim effectiveness (like 10 or 20), at these very low speeds it makes your aircraft react to elevator control (joystick movement) like it was flying at normal speeds.I.o.w.: it "helps" the elevator.The gauge automatically switches off:- When the autopilot is ON- When the flaps are UP.The reason there are a number of variants the gauge, is because the code of the gauge only works correct for a specific number of flap positions an aircraft has. Hence a 3pos, 4pos, etc. version.The simplest way of determining the number of flap positions your aircraft has, is to look in the aircraft.cfg Flaps section (as decribed in the Readme).But again, the only reason why you would want to use this gauge is for aircraft that somehow uses vertical thrust (to allow very low airspeeds); like a Harrier, JSF or Osprey (with turnable rotors). Since vertical thrust is impossible to model in FS (other then giving the aircraft a "helicopter engine", but then it won't fly like a normal aircraft), this "trick" helps to overcome one problem that designers have trying to add a simulated form of "vertical thrust" to an aircraft.Cheers, Rob Barendregt

maybe I am nuts but try it with an airliner like the pss airbus........seems to hold a pitch attitude fairly well.......russ.......

Hmm.. Are we talking about the same gauges here ????( *PosAutotrim.xml , where "*" is a number 3,4, .. or 9)If so:It DOESN'T hold pitch attitude.If you experiance that, it's purely coincidental.I assume you are talking about a situation where flaps are up and/or AP is engaged.If so: the gauge does ABSOLUTELY NOTHING in this situation.Rob
