Which of the following is NOT listed as a heritage aircraft?

The Eurofighter is the correct choice as it is not classified as a heritage aircraft. Heritage aircraft typically refer to older or historic aircraft that have significant historical value or are part of aviation heritage, often being retired from active service and preserved for educational and commemorative purposes.

In this context, the Lancaster, Chipmunk, and Dakota are all aircraft with notable historical significance. The Lancaster bomber played a crucial role in World War II, primarily as a heavy bomber. The Chipmunk, originally designed in the 1940s, is well-regarded as a trainer and has been a staple in flight training for decades. The Dakota, known as the Douglas DC-3, is historic for its contributions to both military and civilian aviation, particularly during World War II and in the early years of commercial aviation.

In contrast, the Eurofighter is a modern multi-role fighter aircraft that is currently in active service with the RAF and other air forces around the world. Its contemporary design and operational status distinguish it from those aircraft recognized as part of aviation history, reaffirming that it does not fit the criteria of a heritage aircraft.
