737-800 N1 limit changes with pack / bleed switches
Hi,

When on the ground and with engines off and APU, if you turn either pack / bleed switch AUTO / ON this should decrease the FMS N1 by a set amount ie .8%

But i’ve also read its the ONLY the position of the APU BLEED SW will have the effect on the FMS N1%

Anyone care to share the Boeing AMM referance for this please?
