A350 燃油泄漏程序的 LIMITATION 中包括"BTV: DO NOT USE"
空客解释为，燃油泄漏时不能使用反推，但是 ROW/ROP 计算是基于使用反推的，所以结果不准。BTV 使用的距离就是是 ROW/ROP 计算的，也不准，所以不能使用。
这个在手册中也能找到描述：

Q1:
There's "BTV: DO NOT USE" in LIMITATIONS of FUEL LEAK procedure, Is it because runway of braking mechanism contaminated by leaked fuel?
A1:
The answer to your first point is provided in TR 80610206. For your convenience, you can find just below the provided answer:
In the fuel leak procedure, it is recommended to not use the reversers during landing roll.
On the other hand, the ROW/ROP computation is based on the standard use of reversers (idle reverse if runway condition/braking action is 6, max reverse otherwise). As the use of BTV is linked with the ROW/ROP computations and to avoid unexpected situation (for example: EXIT MISSED) it is recommended to not use the BTV in case of a fuel leak situation (like for other situations where the landing distance is impacted).
