BVLOS: Masa Depan Operasi Drone Jarak Jauh
Beyond Visual Line of Sight (BVLOS) adalah kemampuan menerbangkan drone di luar jangkauan visual pilot - membuka peluang untuk delivery jarak jauh, inspeksi pipeline, surveying area luas. Namun BVLOS juga membawa risiko signifikan dan memerlukan teknologi canggih serta izin regulasi ketat.
Definisi dan Batasan VLOS
Visual Line of Sight (VLOS)
Berdasarkan CASR 107 dan regulasi VLOS:
