解析：根据题目中的要求，需要持续监控速度指示直到测试结束。选项A中的'Monitor the speed indication continuously until the end of the test.'恰好表达了这个意思，符合题意。选项B中的'IAS shall be monitored continuously until the end of the test.“的意思是'空速指示应该在测试结束之前持续监控”，虽然表达了类似的意思，但并没有具体提到速度指示。选项C中的'Monitor the speed indication as long as the test continues.“意思是'只要测试继续，就监控速度指示”，但没有明确要求持续监控直到测试结束。因此，选项A是正确的答案。
