Abstract
A mobile device such as notebook need to modify its operation in airplane, at least turning off wireless
transmitter. Other operational changes include reduce significantly battery charging rate if AC is
available. That is due to airplane’s limited power capability while airborne.
The current airplane mode is handled manually. The write‐up described to use build‐in mic‐phone for
airplane mode detection. By listening to unique background character inside airplane cabin during
airborne, the notebook device with its build‐in mic can detect airline mode, then adjust device operation
automatically.
