雷達電碼之分配與用途

每架民航機都配備所謂的詢答器(transponder),
它是用來顯示航機資訊給航管人員(ATC),
例如航向、高度、速度、callsign等相關資訊,
而詢答器必須輸入一組特定的號碼,以便識別,
號碼在每次起飛前申請許可時,由航管人員頒發,
這些號碼又因起飛機場不同跟遭遇的狀況,
而有特定的編碼原則,
以下就是台灣地區SQUAWK的用途,

Molson Canadian - The Rant

Hey, I'm not a lumberjack, or a fur trader....
I don't live in an igloo or eat blubber, or own a dogsled....
and I don't know Jimmy, Sally or Suzy from Canada,
although I'm certain they're really really nice.

I am Canadian

I know this place is where I am
No other place is better than
No matter where I go I am
Proud to be Canadian
