    二五年六月十一日下午，一名飛行員駕駛一架隸屬topjetaviation有限公司的robinsonr44型直升機，以目視飛行規則作私人飛行航班，由北丫起飛，第二次運載三名乘客往舊啟德機場的香港飛行總會。
  2. Metrojet limited operates three g200 aircraft for non - scheduled passenger services in the region. hong kong express airways limited ( formerly known as helicopters hong kong limited ) operates two s76 and two as350b helicopters for local passenger charters and aerial works, and for passenger charters between hong kong and macau

    香港商用飛機有限公司擁有三架g200型飛機，在區內提供不定期客運服務。港聯航空有限公司（前稱港聯直升機有限公司）擁有兩架s76型和兩架as350b型直升機，在境內提供載客包機服務及進行空中作業，並提供來往港澳兩地的客運包機服務。
  3. Cnsatm systems will minimise airspace constraints and reduce traffic congestion, and this will enable aircraft to operate within their most optimum flight envelope, commensurate with achieving a marked increase in flight safety

    衛星通訊、導航及監察航空交通管理系統可把空域限制減至最少，紓緩交通擠逼，從而讓航機充分發揮其性能，並且大大提升飛行安全。
  4. It is one of the hottest international research topics for the small unmanned helicopter to be controlled, whose flight mode currently is limited mainly by remote controlled, while the research of automated flight control is on the rise

    對小型無人直升機的飛行控制目前是國際上的一個研究熱點。無人直升機的控制方式主要局限於遙控飛行，對自主飛行控制的研究則方興未艾。
  5. For a given finite connected graph f, a group h of automorphisms of f and a finite group a = z, du, kawk and xu ( see [ 6 ] ) get some new matrix - theoretical characterizations to classify all the connected regular coverings of f having a as its covering transformation group, on which each automorphism in h can be lifted

    設為有限連通圖， h為它的自同構群的一個子群， a為給定一個初等交換p -群。杜少飛， kawk和徐明曜用矩陣的方法將的正則連通覆蓋圖進行了分類，其中以a作其為覆蓋變換群，並且h可提升。
  6. The problem is then fed to a nonlinear programming routine to solve for all parameters. the flight dynamics model with yawing motion of uh - 60a is given, scale factors of state variables and control variables are applied based on the consideration of algorithm convergence. then, the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits, faa regulation and so on

    首先，建立帶偏航運動的直升機點質量模型，然後對狀態變量和控制變量進行無量綱處理，因為狀態變量和控制變量量值相差較大，這使得優化演算法收斂效果變差，所以需要選擇適當的縮放因子，最後把直升機單臺發動機停車后的飛行軌跡表示成一個最優控制問題，即在考慮直升機性能限制和far規范后，指定一個優化性能指標，選擇合適的路徑約束，然後再解最優控制問題。
  7. He said the helicopters could not be modified for military use because of their flying ranges and for other technical reasons

    他說這種飛機由於飛行距離和其它技術原因的限制，不可能被改裝為用於軍事用途的直升機。
  8. So far this reality has limited spaceflight to multistage expendable rockets or the space shuttle, which is assisted by strap - on fuel tanks and solid - fuel boosters that are jettisoned during ascent

    目前為止，這個事實使太空飛行限於多階段擴張式火箭或是太空梭；後者在上升過程中拋出附加的燃料箱和固體燃料助力器。
