When you unexpectedly enter instrument meteorological conditions, the priority is to regain control by flying with reference to the instruments and stabilizing the flight path. The corrective actions focus on communication within the crew, establishing a reliable instrument scan to determine attitude and flight path, and setting conservative, safe parameters to maintain terrain clearance and begin a return to VMC if possible. Announcing that inadvertent IMC has occurred helps coordinate the crew and ensures everyone is focused on the same task. Establishing an instrument scan is essential because visual cues are unreliable, so you must rely on the attitude indicator and other flight instruments to hold a stable, controlled flight. Setting a safe altitude, airspeed, and heading is about maximizing your margin for error and making deliberate, predictable adjustments to steer toward better weather or a safe area. Squawk 7600, on the other hand, is the transponder code used to indicate a loss of radio communications. While important in a separate communications failure scenario, it is not part of the corrective actions for inadvertent IMC itself.

Understanding how the Flight Director’s relationship with the AFCS is communicated to the crew is key. If the Flight Director becomes uncoupled from the AFCS, an aural warning is issued to alert you that the FD cues are no longer being provided by the autopilot system. This alert is there so you don’t rely on FD guidance that isn’t actively controlling the aircraft, signaling you to manually monitor flight attitude and, if needed, re-couple the FD to the AFCS. Because of that alert, the statement that there will be no aural warning is not correct. If you hear the warning, check the AFCS/FD status and restore coupling as required.

Battery endurance depends on how much power is being drawn from the DC system. When DC powered equipment is secured, you reduce or remove nonessential loads, which lowers the current drawn from the battery. The 30-minute figure is a baseline under typical conditions, not a hard limit. With less load, the remaining battery energy can last longer than 30 minutes. So, the statement that battery life can extend beyond 30 minutes when DC powered equipment is secured is the most accurate.

Go-around is the maneuver to discontinue a landing and climb away safely. You must have enough altitude and rotor authority to transition from descent to a stable climb, achieve the necessary airspeed, and gain translational lift while avoiding obstacles or the ground. That safety margin is why the limit is set at 25 feet above the surface (AGL/AWL). Below that height you don’t have sufficient time or clearance to safely perform the go-around, increasing the risk of a hard landing or collision. The lower options are too close to the ground to execute safely, while the higher option is more conservative than required.
