During an IFR flight, if you observe a steady change in your indicated altitude, what does this signify?

A steady change in indicated altitude during an IFR flight signifies that the aircraft is either climbing or descending. This is a fundamental understanding of basic flight instruments and how they function under IFR conditions. When the altimeter shows a consistent increase or decrease in altitude readings, it indicates that the aircraft is actively changing its vertical position.

This concept is crucial for pilot awareness and flight management. Understanding altitude changes is vital for maintaining safe flight levels, adhering to air traffic control instructions, and ensuring proper separation from other aircraft.

While consistent performance and turbulent environments can influence how altitude is managed, they do not directly indicate a steady change in indicated altitude. Similarly, a navigation system malfunction would not specifically cause a steady change in altitude readings but might instead show erratic or incorrect data.
