hay FS addicted ppl, i play FL2002 for about 1 month and i have plenty of questions for you (go figure why)!

ill spare "some" and ill ask u the ones that i find most important:

1: 1 mach= sound speed, right? so, what happens when it shows 1800 in my airspeed indicator? by the way: its 1800 what? km/h? miles/h?

2: when i find a carrier and dl, can i start the game on it?

3: what r flaps? what do they do? (i know, dumb question)

4:why cant i land with my f-16? it just slides trhu the road, then dirt till it crashes in a house or dives in the sea. once i landed but it was miles away and the plane was with a wing one the floor and thats why it stoped.

and last, 5, whats the trick to align myself with the runway? sometimes i cant even find the airport :S

PS: u dont have to answer ALL the questions.
PSS dont tell me to look in the forum, thats what im doing right now... plz answer.

Flaps are high lift devices, meaning they provide more lift but at slower speeds. This is of course desireable during an approach since you need less runway to stop the aircraft. There are many types of flaps, some more common than others. Most airliners have flaps both forward (leading edge) and aft of the wing (trailing edge)

It's very easy to notice the flaps when they are fully extended, they droop down quite abit on the trailing edge, creating a larger upper camber which gives the wings more lift.
Do flaps have drawbacks, of course they do. One thing is that with the addition of lift, you need more thrust to maintain the same speed since flaps creates DRAG. The more flaps you extend the more drag you will have.

Speed is btw measured in KIAS (knots indicated airspeed) since it is the velocity of the airflow over the wings that matters. 1800 is not a realistic value neither for IAS nor MACH, so I think you're looking on the ALTITUDE indicator, and not the airspeed prehaps?

Hope this helps abit, I'm exhausted after a hard days work so I'll head for bed now

Welcome to SimV btw!

nexus, thx for the information. beleave me, u really helpped, now i understand what r flaps (i knew it had something to do with landings).

that 1800 thing was my speed, i know a mach is 1000, i read it somewhere (i was flying an F-15, awsome plane).

btw, do u know where i can get a carrier?

anyways, thx a lot, and i hope we can do a flying (online) some day. bye

Hi Bo...!
Forget all about F-16's, Jumbo 747's, helicopters, carrier landings, etc....
Fire up FS 2002, go for lessons, and spend a couple of weeks/months learning how to fly in a Cessna 172.... 8)...!
Once you have mastered that, and got your licence, then you can go a step up and practice the next level.
You will be surprised what you learn by taking flying lessons first in the simulator.... 8)...!
All your questions will be answered there... Wink

...!

Cheers... Grin

You've been given expert advice. There are aircraft that will clock above 1800 knots ias, if you have them. My XB70 Valkyrie will hit at 2800 ias at 10000' msl. Not realistic. Just FS allowing it to take place. 200 ias at 100000'msl and mach 4.1 is more like it. Although, the real plane did not make it quite that fast. You're doing OK

The Mach number is the ratio of speed in relation to the speed of sound in a fluid, in this case air. Mach 1.0 is the speed of sound, Mach 2.0 twice the speed of sound & so on. The Mach number is displayed on a Mach meter. The speed of sound varies depending on altitude & temperature (around 760 mph at sea level & 660 mph at 40,000 feet). 1800 would be your airspeed, probably measured in Knots. 1 knot = 1 nautical mile per hour. Some ASIs are calibrated in mph or km/h.

I believe 1 knot=1.15 mph....I know that doesn't seem like a big diff. but at 500knots you are actually doing 575mph
