When ROC airplanes fly to Macao, they must communicate with a mainland Chinese air traffic controller. While Taiwan and the mainland maintain an antagonistic relationship, will this be lumped in the general category of "communicating with the enemy"? Tsay Ching-yen had well-laid designs in mind for surmounting these barriers. He arranged for special-case permission for such matters as allowing flight crew into the country and contacting air traffic control personnel.
更棘手的是，澳門沒有自己的飛航情報區，而是隸屬廣州飛航情報區，我國飛機飛行途中，勢必要和大陸航管單位通話，這在兩岸仍然對峙的情況下，會不會被扣上「通敵」的大帽子？
