well, i think it can be dificult to answer this question. (in real life) what tells the pilot to the atc and the atc to the pilot? What is the normal speed ( on a big plane) when they are taxiing? when did the pilots down the flaps? How many flaps needs the 737 to take off? When the pilot has took off: when does he retract the flaps? and the landing gear?what does a pilot do when he land and stop at a gate? Does the airlines need to tell to the airport that they are going to go to thath airport on a day? How much are the airport taxes for the planes (landings..)?
thanks in advance

i will try answer what i can.
i dont understand the first question so i will have to leave that one.
Normal taxi speed for a large aircraft varys i have heard its a company to company thing, but on straight taxiways i have heard 25 to 30mph.
Retraction of flaps after takeoff happens in stages to go with the speed(not sure on exact speeds) landing gear, usually as soon as a positive rate of climb is achieved, or soon after.
and airport fees vary again from airport to airport.

i will leave the rest for better informed people to answer

I'm with CraigL on this one. Taxispeeds are not determined by speed restricitons (like on the highway, for example). But to make a 90degree turn on the ground, pilots like to be below 10kts to avoid a sudden turn which is uncomfortable for both crew and passengers. On straight taxiways I estimate the speed to about 25kts and below.

Regarding the flap settings, this is detemerined by many variables, like temperature, Gross weight and wind conditions, for example. But take offs with 5 and 10 degree flap settings are common.

Landing gear is retracted around 50feet above the ground (when you have a positive rate of climb readout on the VSI)

Flap retraction speeds are different for each aircraft, and I don't have any speeds in my head ATM, sorry Embarrassed

The airplane doesn't have to contact the airport and say "Hey guys, is it okay for us to land at your airport?"
See, they know you're coming. Your flightplan has to be approved by EVERY ATC along your route, so they expect you allright

Take care!

I have to agree taxi speeds differ from comany to company but i have knoticed when they are close to there flow window or wheels up time they go in a hurry Espically southwest, i dont think i have ever seen a 737 go any faster on the taxi ways then southwest. lol at the airport i work at. After there Landing roll out the conversation goes liek this.

"Southwest 1234 say gate"
"Were going to Alpha 4 "
1234 turn right on the airline ramp taxi to your gate my freq.
or
"Southwest 1234 say gate"
Alpha four"
1234 comany is just pushing out of that gate turn right on the airline ramp Nose wheel on the solide double yellow line and it will be the Second set of hold bars you come too.

ATC dosnt always know whos going where. Hope i could answer your qiestions.

At a regional civilian airport in the UK you're looking at £600 to £1200 pounds for a small airliner...

I dont usually say this but i think you should take the fs lessons. They tell you about these things, flap and gear retracion and so on.

Now if something goes without saying, then why do people say it??&&&&http://www.homepages.mcb.net/bones/04fs/MP/9320.jpg

Cunning plan, well suggested. Its take 11 months for someone to think of that!

This is true. Once you get a good rate of climb on the VSI it usually means you have flown out of "ground effect" Usually as long as you have control of the aircraft and are sure that everything is working fine...up they go. I do not think that there is a "set" retract hieght.

I read somewhere that it is considered safe to only retract flaps at or above 500ft AGL. thats what I usually do in FS, but I mostly fly single pistons, or medium twin pistons. I dont know anything about airliners.

When in my 172 my instructor had me hold flap until 200 ft agl.(for touch and goes only mind you)I never take off with flap unless short or soft field. Mind you that is only 10 * of flap as that is how I was taught to land. I do know that when doing my circuits I turn to cross wind at 500 ft agl. But also, again, all instructors are different. I wonder if the article you read was on an ILS departure?

I dont think so, Im not to interested in anything to do with IFR flight. You know what, It might have been in the checklist or manual for an FS airplane, possibly the Mooney Bravo.

Well I would say a good speed for most aircraft is about 20-25 sometimes at big airports (KORD) the ground controller will tell the pilot to go faster than 5mph , also you will have charts or should which will tell a lot of important information .
