How about Direct SBJ, pick up V3 and be on your way

A question to IR pilots.

Suppose we have the following situation: a flight departing from
MMU rw 23, cleared as follows: "Morristown 5 dep, vectors to BIGGY,
then V3, MAZIE, etc... 2000 feet, expect 4000 10 minutes after
departure, dep freq, squawk etc..."

Now, during climb-out via heading 210 we lose communication. It is IMC.
Standard question: what altitudes and routing you'd fly? The
aircraft we're flying is /U, so we can't navigate direct BIGGY.

First question: would you keep flying the DP, i.e. left turn 160?
If so, for how long would you fly heading 160 after you turn? Lost
comm instructions in the DP do not apply to us since we're southbound.
In order to get onto V3 you'd probably need to fly direct SBJ, and
proceed from there, but SBJ is not part of your clearance?

Second question -- the altitude: OROCA in the quadrant is 2900. MSA
provided by Jepp for CAT is 2000 in this sector. Would you climb
to 4000 right away, or you'd wait for 10 mins? MEAs of the airways
in that vicinity are 2300 and 3000 feet.

I would wait until 10 min to climb to 4000, and climb initially only to
the appropriate minimum IFR altitude for that sector or MSA or whatever
was appropriate, if higher than the current vectoring alt. The EAC time
is probably to get clear of inbound traffic above, so going there right
away may cause ATC to have to reroute traffic over you.

You would probably be ok to proceed direct on a 45 deg intercept heading
to V3 if that made more sense then direct SBJ. I think that in a comm
failure situation where options are presented, you are ok as long as you
act reasonably and don't head off in odd unexpected directions. ATC is
going to deduce what you are doing pretty quickly and make allowances.
