Taxi_speed.lua v1.1
created by Mike Gromley December 2019
this script will maintain a taxi speed close to the
speed set by the user by adjusting the throttle and
brake to maintain speed.
Revisions Version 1.1
Version 1.2 by RAJ 03/12/2022 to work for ToLiss A321
also works for JD A330, but not FF A350
1) Added disconnect master on toe brake press
2) Added BetterPushback commands if it is installed
BetterPushback is the work of
*Click on one of the two speed boxes to open/close BP panel
3) Fixed (hopefully) the throttle sticking on occasion
Usage
1) set the speed you would like to taxi
with the mouse wheel on Taxi Speed boxes.
2) Master has to be on
3) Park brake has to be off
4) It is disabled in the air
5) It is automatically disablled if you advance the throttles bast 45%
6) It doesn't hold the exact speed that is set but in the area, usually by 1-3 knots
In this version you can arm taxi after landing, retract flaps, and retract spoilers
in any combination.
