經過了幾次基本的飛行課程之後，接下來的訓練便是將這些基本的內容全部融合在一起，然後不停地重複這些動作，大家稱之為Circuits。
"無間"一詞的來源相信大家也都知道，無間地獄在佛教傳說中指永遠不死，不斷受苦，是最殘酷的折磨。
對有經驗的飛行員來說，Circuits不過是家常便飯，每天進場離場都能直覺反應，不過對一個剛有翅膀的蒼蠅來說，這真的是無間地獄....

說真的在這算是很幸運，Vr=55kts Vs=40kts，再加上有glass cockpit，一眼就知道全部的performance，還有三個不同方向的跑道，隨著風向調整，有很多很多別人沒有的優點....只可惜一點，蒼蠅頭上少了大腦多了大便，一點點側風，一點點不正確的profile，就會讓腦袋裡的大便沸騰，然後radio叫不出來、check list全忘光、高度超過規定、bank角度不對、屁股亂搖，最後在跑道頭高爾夫球場上空才看到G1000上所有數據全是錯的，祈禱教官大叫"I have control!"卻聽到"Wow, today is Friday, so many people playing down there."看高度感覺自己又要摔飛機嚇得手不敢放掉，Power卻被拉到idle.......BANG!左歪右扭吃光所有跑道教官又Full power 繼續 rotate重複上面所有的動作。
在空中一直想落地想落地想落地，進場又看到G1000數據全是錯的，恨不得大叫Go around快點離開地面回到天空。
雖然知道這是基本到不行的訓練，但現在對我而言真的就像不間斷的折磨，就這樣一次又一次的輪迴著.....
