None. Nor is there any point in delaying clearance issuance if the aircraft
is using the NDB, as ATC is providing radar monitoring.

One reason for delaying the clearance when using the NDB might be that,
although ATC may be radar monitoring, once one descends below 4000', there
is no direct radio contact with ATC.

Radar monitoring is required even if the aircraft is executing the GPS RWY
33 approach.

Why do you think this delay in issuing the clearance is a policy at the
Boston ARTCC?

If it is not justified by the FAA published procedures, do you have a cite
from the manual that I could present to the supervisor at the Boston ARTCC
to support its elimination?
