B737NG APU Restart
Hi folks,
got a few questions regarding the APU in the NG:
1) Assuming the APU is running and you move the start switch to OFF, the APU will normally start a 1 minute countdown. Is the shutdown sequence cancelled if you move the switch back to START?
2) Assuming the APU is spooling down, when is the soonest you can restart the APU? When the RPM reaches 7%? Or is a restart inhibited for a few minutes?

(Don't know if there are multiple APU variations but I am referring to the GTCP model)

Thanks!
Mark
