While enroute to KCHD, if you lose communications in IMC approaching POPKE, what should you do?

When approaching POPKE in IMC (Instrument Meteorological Conditions) and losing communications, the appropriate action is to proceed to the Initial Approach Fix (IAF) for your planned approach to KCHD. This option is based on established procedures for lost communications during instrument flight operations.

In this situation, the pilot should follow the route as indicated on the navigation charts while proceeding to the IAF, which is designed to assist in the transition to the final approach. This approach ensures the pilot can maintain safe and controlled navigation, utilizing the existing air traffic control procedures that account for lost communications.

The other options, while they may seem reasonable at first glance, do not align with standard operating procedures in instances of lost communications. For example, returning to the last fix might lead the aircraft away from the intended destination, creating confusion and potential air traffic conflicts. Entering a holding pattern without a communications plan could also lead to complications, as it can be challenging to effectively manage holding patterns without knowing air traffic control's intentions. Proceeding to the destination without a plan not only jeopardizes the safety of the flight but also goes against the structured approach required during IFR operations. Thus, navigating towards the IAF provides a clear and methodical path forward following the loss of
