Final answer:
Aerial refueling is a technique used by military aircraft to receive fuel from another aircraft while in flight. The question is about the arrival time of the tanker before the ARCT and how it establishes a holding pattern.
Step-by-step explanation:
Aerial Refueling, also known as air refueling or in-flight refueling, is a technique used by military aircraft to receive fuel from another aircraft while both are in flight. In this case, the subject is related to the RV Delta aircraft and the tanker aircraft engaging in air refueling.
The question asks how early the tanker should arrive before the Air Refueling Control Time (ARCT) and how it establishes a holding pattern. The time the tanker arrives before the ARCT depends on various factors such as distance, speed, and fuel consumption. The term 'hand holding pattern' refers to a holding pattern flown using visual reference points rather than relying on navigation aids.
Therefore, the answer to the first part of the question is that the tanker should arrive at least [insert answer] before the ARCT, while the answer to the second part is that it establishes a holding pattern using the [insert anchor point] as a reference.
