Taxi speed
Hi,
What is the normal and maximum taxi speed (in knots) for an RJ, 737, and 747 in normal operations? I'm just using those as examples, feel free to mention any others. Also, I'm not looking for maximums or AFM limiations, just the day-in day-out taxi speeds and the maximum that a crew would use to get to the runway for an expedited takeoff. Thanks, Hilton |

My guess here is that if you're taxiing fast enough to get an indication on the airspeed indicator (tape display?) you're going too fast... (unless you're heading upwind maybe) I don't know if there is a max taxi speed, usually it's at the pilot's discretion - interesting question though. |

As an airline passenger, I typically see ~ 15 MPH (~ 12.5 knots) on my handheld GPS, with the occasional 20 MPH leg on a long, straight taxiway. In my Spam can, the GPS groundspeed typically shows ~ 10-12 knots on the high end. |

Taxi speed
When the 747 entered service, the pilots used the inertial
nav to control speed, because it was said, that it was too hard to judge the speed visually because of the high cabin. I a straight line, you can taxi fast, but no airplane corners like a F1 race car. Slower is better.

Thanks, Hilton We used to taxi our CRJ 200's around 20kts. Usually on one engine. Two at idle, no passengers the thing will taxi at 40kts. Michelle (former instructor mechanic) |

747 and 777, 15 knots. At least that's what we, as mechanics were taught.
Slowing to 8ish in turns. "Hilton" wrote in message news Hi, What is the normal and maximum taxi speed (in knots) for an RJ, 737, and 747 in normal operations?

Obviously the airspeed indicator isn't much use in these situations... (This is from a sim 'pilot', so might seem like a daft question!) Andy |
