Welcome to the Sim V Forum.

Taxiing does take a while to get the hang of.  Advance the throttle slowly and try and find a setting that allows you to creep along at around 20 kts ias.  The default AI travels at this speed so you shouldn't collide with them too often.

Ask the ATC for directions and you will get a pink line showing the route to wherever you want to get too if you get lost.  Best of luck.

This is one of the few examples real world pilots have the advantage. Most airliners can taxi with the throttles at idle, so they dont need to think about adding power, really. I know the 737 can do this, and I'm pretty sure same thing applies to most of the modern airliners out there.

Airports generally has a speed limit of 25 kts during taxiing. When approaching a turn (say 90 degree) with a jet, your speed should not exceed 10kts.

It's an not an official rule (My bad,), but most operators avoid taxiing over even 20kts. A taxispeed over 25kts is considered abnormal if it's not on a high speed taxiway, where speeds can reach as high as 70 knots.
There are some reasons for this. Firstly speeds over 20kts tends to increase airplane vibration, and secondly, to avoid excessive break heat-up and wear.

The info above is from a real 737 Type Rating Instructor & Examiner. What more proof do you need?

Check the taxi briefing manual at smartcockpits.com  Wink

That's more like it! And your right, or the manual is I should say. Just don't tell Southwest this. We have a term in the industry, that I've heard the contollers use. It's called the "SouthWest Shuffle". When I first started flying, it was more of an issue, but I have noticed in recent years, an increase in taxi speeds. It does make sense, that an airplane that can reach speeds approaching 200mph, before rotation, should be able to taxi at least 40-50kts(circumstances permitting, of course!)! The  scale on the airspeed indicator on the airplanes that I fly, begins at 80kts, which means it's up to the pilot to determine groundpeed below this point. Kinda grey area, as far as imposing and enforcing any speed limit.  Wink

All new Boeings have the speed displayed in the ND, don't know about the Airbus series though, but those speeds are pretty darn accurate  Cheesy

I'm about to lobby for an airport taxiway patrol  Grin

Are there many high speed taxiways around? Where exactly are they found in the world, and can you give an example? I'm unfamiliar with them, and didnt know they existed!

Do you think the FAA should use cop-bikes or Helicopters? Roll Eyes
My airspeed indicator is a "steam gauge", so I would be "Grandfathered" out of that requirement, if you're successful
Tongue .   Something to think about.....if I land at a large airport like MIA with a low amount of fuel, and have to taxi back to the approach end of the runway (which I often do when I land on 9L). I would have to "ride" the brakes to keep the airplane from accelerating. The Fan engine pushes a lot of air, I've used the length of the runway, and now have to taxi downwind and the A/C is light because it has burned most of it's fuel during the flight. Under these conditions, and at IDLE power, the airplane will EASILY exceed 40kts. I use occassional stabs at the brakes or deploy reversers with idle thrust, but I accept the high taxi speed, because I don't want to "drag the brakes" for 2statute miles(the runway is 10,000' long).
JGC welcome to the Forum, get used to this, and if it happens where we get in a long winded debate, and don't answer your question just let us know Embarrassed
Keeping your taxi speed below 20kts is a perfectly acceptable suggestion, and is probably safer. On the larger airplanes, it's neccessary, to make tight turns. On the small ones, to keep them from rolling over. Unfortunately, there are some things the simulator doesn't duplicate well. Three dimensional viewing is one of them. In some situations you just have to resort to external view!  Wink                   Pat 8)

   A "highspeed" is not designated, but is merely a taxiiway that is angled about 30 degrees from the runway, as opposed to 90. Most major airports have them. They are used to expedite operations of Large or High Performance aircraft in "high density" operations. " Take the next available high speed" is a call that you often hear the tower use at large airports. This means that the aircraft should  use any one of a series of these 30 degree exits. Wink

More interesting stuff on Simv-why go anywhere else?

Those 30dg taxiways are great even in sim.

When I had most of my flying experiences,years ago, there were some flying accidents on approach and landing at our local airfield which instilled in me the "get eyes in your #rse,get off the active" attitude and it sems to have carried over in to sim!

I'm starting to think I'm paranoid Roll Eyes

There is a taxispeed gauge you can download and add to any panel.cfg that controls the speed at which the aircraft will taxi, by automatically controlling the throttle.  Just set the speed you want and go.  It also provides instructions for placing the gauge.  I forgot the name of the designer, but just do a search using the words "taxispeed gauge" or something similar.

I work in PHX and the Southwest pilots get moving. Thats a good thing if your wating to cross the taxi way. They will be past you in a few seconds.  Northwest & Delta has to be the slowest.  They just crawl along.  And you half to wait  and wait then wait even longer untill the past.  Then when you start to go thats when NW or DL will increast speed. Just to give you a nice war jet blast in July.  Smiley

Hello,

         When I taxi,I go around 15-20 knots.I just use my autopilot and set IAS to 20 kts or 15,whatever,turn Auto-Throttle on and click IAS,no problem.I know sometimes the runway is long and your starting position is way over the other end and you are dying to go there ASAP but it isn't really realistic to get some thrust higher than 60 kts and then slow down,if this happened,passengers would complain lol,that they were going on a Plane-Car.Anyways,15-20 kts is good.The stock MS FS AI planes go around 5 kts,too slow so I just turn,sip onto another runway and pass them and come on back.

Ender Baron is referring to Rob Berendregt's Pushback Gauge.  I have it installed on all of my panels and highly recommend it for controlling taxispeed.  Here's the zip file to search for:

Good luck! Smiley
