On Air Force Phantoms with ASN-48, -56, and -63 inertial navigation
sets and including ARN-101; was the alignment done before or after
engine start?

Thanks,

On the German F-4F (similar to the -E Model) the INS had to be aligned
before the engines where startet. I don´t know the ASN No. of the
system now.

On the C/D/E models the INS was aligned prior to engine start. Part of the Preflight process.

Val is right there !

Here are some pages from the RF-4C Inertial navigation aircrew
handbook.
This handbook is about the LN-12 Inert.nav.syst. which uses the ASN-46
navigation computer.
This is the quick reference part, but also in the detailed manual
there is written this is a pre-flight procedure (usually done by
groundcrew)and nothing written about engine start.
