How can hand-held and tablet-based GPS devices be used during IFR operations?

Hand-held and tablet-based GPS devices are valuable tools for enhancing situational awareness during IFR operations. They provide pilots with real-time information such as the aircraft's current position, nearby airspace, weather conditions, and navigational data, which can significantly aid in decision-making and maintaining safety. While these devices can offer important insights, they are not typically used as the primary navigation source under IFR conditions due to regulatory requirements and the high reliability demanded of navigation tools in such operations.

Using GPS for situational awareness allows pilots to supplement their primary navigation methods without compromising their adherence to IFR protocols. Thus, the correct answer emphasizes their role in helping pilots maintain a clear understanding of their environment and situation during flight, rather than serving as primary navigational tools or being limited to emergency use.
