What are the positions that the receiver moves from and to during the boom operation?

The receiver moves from the Pre-contact position to the Contact position during the boom operation. In aerial refueling, the Pre-contact position is the initial stage where the receiver aircraft approaches the tanker and aligns with the boom. Once the aircraft is in the correct position, it transitions into the Contact position, where the boom engages with the receiver's receptacle for fuel transfer. This movement is essential for ensuring a stable and effective connection for refueling.

The other options refer to different terms that do not accurately describe the specific phases of movement involved in the boom operation. For instance, the Standby to Contact transition doesn't reflect the actual sequence of phases. Similarly, terms like Initial to Final and Extended to Retracted do not correlate directly with the operational procedure of boom refueling, which specifically revolves around the pre-contact and contact stages.
