In IFR operations, what should a pilot do if they are unsure about their minimum authorized altitude?

When a pilot is unsure about their minimum authorized altitude during IFR operations, the best course of action is to contact ATC for confirmation. ATC has access to all relevant navigational data and can provide the most current information regarding altitude restrictions and safety requirements for that airspace. Maintaining communication with ATC ensures that the pilot is adhering to safety protocols and helps avoid potentially hazardous situations that could arise from flying at an incorrect altitude.

Continuing to fly without guidance can lead to violations of airspace regulations and increase the risk of collision with terrain or other aircraft. Assigning a higher altitude may seem like a prudent decision, but it's essential to ensure that the chosen altitude is appropriate and does not conflict with other airspace users. Referring to onboard guidelines can be helpful, but those resources may not provide real-time updates or specific information relevant to the current situation. Engaging with ATC is the most reliable method to resolve such uncertainty and ensure safe flight operations.
