In this video, we explore one of aviation’s most misunderstood questions:
## Is PAPI actually mandatory?
Using ICAO regulations and real operational examples, we explain:
* what PAPI really does,
* why those red and white lights are critical for safe approaches,
* when regulations use the word “shall,”
* why pilots may face action for landing without it,
* and why even modern aircraft with ILS and GPS still depend on PAPI.
A practical aviation explanation from both operational and safety perspectives.
