構成燃油系統(tǒng)的組件有位于右翼前緣襟翼外側的加油口， 3個浮子開關 -每油箱一個，用來防止油箱過滿。浮子開關位于油箱頂部測量油量。油箱油量可按要求存貯，浮子開關測量油量并能自動停止加油。電源可由地面電源、 APU或電瓶提供。壓力加油也可人工操作。最大燃油壓力為 55psi。

(5) The distribution system allows fuel to be supplied to the engines and APU. In addition, the system can be used for defueling the tanks and for fuel transfer between the tanks. The distribution system utilizes pumps, valves and truing for engine and APU feed. The fueling station is used for defueling and transfer operations which are only possible on the ground.

燃油分配系統(tǒng)可為發(fā)動機及 APU供油。另外，分配系統(tǒng)可用于油
箱放油及油箱之間的輸油。分配系統(tǒng)利用泵、閥門及渦輪為發(fā)動機及 APU供油。加油口只能在地面進行放油及輸油操作。
(6) Fuel is first supplied to both engines from the center tank and then from the respective tanks to engines. The crossfeed valve allows fuel from one tank to be supplied to both engine. Fuel to the APU is primarily supplied from tank No.1, but it can be supplied from any tank.

燃油 is first supplied to both engines from the center tank and then from the respective tanks to engines.交輸活門允許燃油從一個油箱同時給兩臺發(fā)動機供油。為 APU供油主要是用 1號油箱，但也可從任一油箱供油。

(7) The fuel quantity indicating units measure the weight of usable fuel in the tanks. Two types of quantity indicators are used, one is capacitance indication, another one is a manual measuring stick.

油量指示組件測量油箱中油的重量。一般使用兩種油量指示，一個是容量指示，一種是人工用棒測量。

(8) Digital fuel quantity indicators show the weight of fuel ing each tank. Each indicator consists of a single chip microcomputer system and a digital liquid crystal display(LCD). The microcomputer measures the capacitance and resistive current in the tank units. It monitors the leakage current and when is reaches an unacceptable level, an drror code o through 10 illuminates to assist in troubleshooting the system.

數(shù)字油量指示器顯示每個油箱中的油量。每個指示器包括一個單芯片微型計算機系統(tǒng)和一個數(shù)字式液晶顯示器。微型電子計算機測量油箱中的容量和電阻電流。它監(jiān)控著泄漏電流，當泄漏達到一定程度時，會指示一個 0到 10的代碼，以幫助進行系統(tǒng)排故。

(9) The measuring sticks are graduated tape which can be pulled down for reading of fuel height.

測量棒是一個刻度尺，它能夠放進油箱來讀出燃油深度。
