Real Slim...the NNc you're talking about it's specific for the 400/800 series...so ,if 'you don't feel able to add something....".quite a professional remark from your part..
But ,maybe ,you flew only 800 series,so it's ok ,then....it is a bit different from other 737 series,you should know..
Did you read my entire post,or you just stopped after the first phrase...deeply offended,i guess..
I-2021 ...departing under MEL on such a case will restrict you to FL 250 ,if I remember correctly.This is exactly for a malfunction like the one you've imagined.In such a case,I guess,I'll use a 'crossfeed' for the remaining pack.
And if this is not working,i'll follow the 'both pack trip off light' nnc..
