@old fella :maybe a little off topic, but one question to you- some time ago , as we waited on the ramp for passengers , a military c130 taxied to the runway and took off . (with serious sound on taxi
)
it sounded for me that they taxied with 100% rpm- there seemed to be no further spool up of the turbines at initiating the take off roll. is it so? do you taxi the c130 with fully spooled up engines?
