Hi guys,

Got my FS9 yesterday, very awesome!!!  I got one question tho, whenever I accelerate to over an indicated airspeed of 360kts, I get the master alarm going off.  Is there a reason for this, as I know that I can go faster than that - my 747-400 is barely ticking over to maintain this speed

Just another basic question - can anyone explain trim for me as the tutorial explanation is a bit convoluted, and my joystick landings are... ugh, best left unsaid.

Cheers

Different aircraft have different maximum airspeeds. Also the higher you climb the faster you'll go (ground speed wise not indicated airspeed).
As for trim, it simple allows you to adjust the flight surfaces (e.g. ailerons, elevator or rudder) so that the plane will continue to fly straight and level or maybe in a gentle climb or descent or whatever without any input from the pilot
Best to practice flying on a smaller plane before trying the 747 methinks 8-)

aircraft are limited for airframes due to stress so flying over the max airspeed could cause structural damage and you falling out of the sky.

When you fly on a liner, your indicated airspeed is always around 300 knots, this doesn't mean that your true airspeed is such. In fact, depending from flight level and air density, you are flying at a WAY higher real speed, and depending from winds your ground speed might be even higher (if the wind blows behind you) or slower (if the wind blows in front of you) than true airspeed.

Trim, well, trim is a quite complex matter to explain, but in a nutshell is a set of adjustable moving little surfaces on the rudder, elevator or other moving wing surfaces that allows the plane to move in the air at different speeds keeping the desired flight attitude with little to no force applied to the yoke or pedals.

I dare give you two suggestions: 1) follow the flight lessons in FS9 before trying to fly seriously (simple flight for the heck of it doesn't count ). 2) start from little to grow in the bigger, meaning start with the Cessna to grow in the Lear, in the 737 and onto bigger and more complex planes.

I spent most of yesterday evening working through a fair few of the flying lessons, this morning I was mastering ILS landings in jetliners.  THIS IS AWESOME!!!  (Sorry  ::)) Not yet had a good look at the VOR system, mainly using the GPS and Autopilot and filing Flightplans.  I'm having a great time in the 737, found the Learjet lovely and straightforward this morning to get used to a high-power jet.  Am working on my landings at the mo, I took the 737 up onto the Bristol (UK) traffic pattern and saved, and now I'm taking repeated attempts at landing it, getting quite good at it.  My problem is I come in slightly too fast and too low, however the ILS is improving this.

BTW, I'm very interested in downloading selected 757/767/Airbus models, and also a few smaller 'cityhopper' aircraft, Fokker F28s, MD80s, other small jets, etc.  Is there any one that you can recommend of each?  I have a vague idea how to install them as I've done a lot of MS TrainSim over the last few years and I gather the file structure is similar.  I guess I'd better go read up how to do it  ;)

If you need new planes the only thing you have to do is going here: http://www.simviation.com/downloads.html

Enter the FS2004 section and go shop.

Have fun.

Ok, so IAS is very inaccurate.  Why, and what is the point of displaying it then if it is that inaccurate?

Because IAS is important to the working of the plane.

Study, study, study, put a little experience together and you'll see.

greenhorn, this is a common misunderstanding when people are starting off. The higher you go the thinner the air - so the Air Speed Indicator (which works by measuring air pressure) will tend to 'under-read.' In a jet, at height, you should not normally exceed '300 knots indicated' - at say 35,000 feet that's well over 500 true airspeed.

Best way is to do what real jet pilots do - climb out at 250 knots indicated (that's the 'speed limit' below 10,000 feet in most places). Above 10,000, maybe up to 300 knots. Above 20,000 feet, switch to Mach. speed, say Mach 0.65 in the climb, Mach 0.75 - Mach 0.8 cruise.

Mach speeds are computer-calibrated to allow for the lower air pressure at height - they're the nearest thing you'll get to 'true' airspeed.
