What two elements are required for an inflight alignment?

• A. A GPS track and SLUF
• B. SLUF and an EGI check
• C. A GPS track and EPU check
• D. Altitude data and GPS track

Answer: (A)

The correct answer highlights the importance of integrating data for inflight alignment, specifically using a GPS track and SLUF (Setup Location Update Frequency). Inflight alignment is a critical process that ensures the aircraft’s inertial navigation system is accurately synchronized with the real-world location. The GPS track provides real-time positional data, which is essential for aligning the inertial sensors of the aircraft with global positioning coordinates. SLUF further enhances this by ensuring that the system updates its location data frequently enough to maintain accuracy, particularly during flight phases when precision is paramount. While the other options include elements that might be relevant to various navigational checks or aircraft systems, they do not both directly address the requirement for alignment in the context of inertial navigation specifically. Thus, the combination of a GPS track and SLUF is integral for achieving accurate and reliable system alignment in flight.
