until the last C42 event, by which time the student must attain
G/4.

MIF performance from one block to the next within stage or

proficiency when a G/4 was required on previous block MIF,
2. The maneuver was not a check ride/safefor-solo
critical (+) item,
3. The IP is satisfied the student is ready to
progress to the next event.
(b) The IP must award an overall unsatisfactory if:
1. Regression was to a U/2 where F/3 or G/4 is
required on previous block MIF, or
2. Performance on the same maneuver for two
consecutive events resulted in an F/3 where a G/4 is required on
previous block MIF, or
3. There was regression on more than two items
during an event.
