Hi, I found this script somewhere on the Internet. It's pretty useful when comes to calculate the touchdown vertical speed and acceleration. However, in PMDG 777 I've always got very high G (about 2.5-2.9) though my V/S was just around 100fpm. I don't know why, but I'd like to share the script with you. If you have any idea about my issue, please let me know.
Sincerely,
Thinh.

function landingflaps(off, val)
if (val > 5000) and not armed then
if ipc.readUW(0x0366) == 0 then

end
end
end

function onground(off, val)
if val ~= 0 then
airspeed = math.floor((ipc.readSD(0x02BC) / 128) + 0.5)
if (airspeed > 30 ) and (armed == true) then
armed = false
landvs = -math.floor( (ipc.readSD(0x030C) * 60 * 3.28084 / 256) + 0.5)
landG = math.floor((ipc.readSD(0x02BC) / 62.4) + 0.5) / 100
