Don'tSink,
I've to disagree with you.(My apology if it
sounded rude,which I do not mean to be)
Having an Antiskid inop inflight,QRH says
AUTO BRAKE SELECT SWITH...OFF,Brake with
caution.BUT it never tell you to put the
ANTISKID switch to OFF,reason being the antiskid system detected a fault in the system(as we all know),the remaining system
on other wheels may still provide you with
a wheel speed info to generate a autospeed-
brake command and antiskid protection on the remaining wheels.Thus we donot kill the whole antiskid system by putting the ANTISKID OFF.
However,Your test give you SPEED BRAKE DO
NOT ARM is because having the whole system
off,there is no wheel speed info at all.
