✈️ 1. To avoid interference with aircraft systems
Your phone constantly sends radio signals (cellular, data, Bluetooth, Wi-Fi).
When hundreds of phones do this together, those signals can interfere with:
cockpit headsets
navigation instruments
communication between pilots and air traffic control
The risk is small, but aviation works on zero-risk tolerance.
📡 2. Phones don’t work properly at high altitude
At cruising altitude:
Your phone keeps searching for towers
It tries to connect to multiple towers at once
This causes network issues on the ground
Airplane Mode stops your phone from stressing the mobile network unnecessarily.
🧠 3. Safety during take-off and landing (most critical phase)
Take-off and landing are when:
pilots need full concentration
passengers must be alert
any electronic interference is least acceptable
That’s why cabin crew are strict during these phases.
📶 4. Why Wi-Fi and Bluetooth are allowed later
Modern aircraft have:
shielded systems
certified onboard Wi-Fi
controlled signal power
So once cruising, airlines allow:
Wi-Fi
Bluetooth headphones
while cellular signals remain off.
📜 5. Aviation rules & international standards
Global aviation authorities require airlines to enforce this rule as a precautionary standard, even if the risk is low.
✅ In simple words
Airplane Mode is not because your phone will crash the plane —
it’s because aviation prefers prevention over regret.
