3. Arcing Penetration (Figure 7-3). This procedure requires maintaining a DME arc for a
portion of the procedure after the IAF and then intercepting a course (radial) to the FAF.

Teardrop Penetration (Figure 7-4). This type of penetration is generally initiated away
from the station (IAF) and requires a penetration turn and the interception of an inbound course.
NDB procedures require this type penetration out of necessity since they are based on a
NAVAID without DME.

Throughout these different penetrations and approaches, the rate of descent and aircraft
configuration should be adjusted as necessary to conform with the published altitude restrictions.
