What are the bank, G's and power setting limitations in ET (I)?

The correct choice outlines the permitted parameters for bank angle, G-forces, and power settings during the maneuvering in the Energy Management Training (ET) phase I. Specifically, a bank angle of 30-60 degrees is acceptable, alongside a limit of 2 Gs. This range is designed to ensure that the aircraft remains within safe operational limits while allowing for effective maneuvering and management of energy in a training environment.

In this context, a bank angle between 30 and 60 degrees strikes a balance between agility and stability, enabling pilots to practice turning flight while maintaining control of the aircraft dynamics. The 2 G limit is a critical aspect because it allows pilots to experience increased load factors without pushing the aircraft beyond its structural capabilities, thus ensuring safety during training flights. The 50% power setting further supports these maneuvers by providing enough thrust for maintaining performance while enabling pilots to develop their skills in energy management.

Understanding these parameters is crucial for pilots as they practice energy management techniques in various flight scenarios, ensuring they can react appropriately to the demands of formation flying while keeping the aircraft within safe operational limits.
