Lesson 4 of 4, 9 min
SELCAL, আর Dhaka থেকে Cox's Bazar
SELCAL
- Selective calling: চারটা নির্দিষ্ট audio tone, পাঠাতে মোটামুটি 2 seconds। Aircraft-এর code মিললে cockpit-এ light বা chime।
- লম্বা oceanic HF flight-এ খুব কাজের: crew HF-এর আওয়াজ সারাক্ষণ শোনে না।
- Flight plan-এ SELCAL code দাও; VHF coverage থাকতেই HF station-এর সাথে contact করে নিশ্চিত হও ওদের কাছে ঠিক code আছে; preflight-এ SELCAL check।
