ACS element text (the applicant demonstrates understanding of)

When to seek assistance or declare an emergency in a deteriorating situation.

Bottom line

An aircraft is in an urgency condition the moment that the pilot becomes doubtful about position, fuel endurance, weather, or any other condition that could adversely affect flight safety. The time for a pilot to request assistance is when an urgent situation may, or has just occurred, not after it has developed into a distress situation.
