A Tribute to Bernard Ziegler
Section titled “A Tribute to Bernard Ziegler”In each era of aviation, there are people who pioneer an idea with such conviction that the industry as a whole will benefit from it. Working for Bernard Ziegler (a.k.a “BZ” as he was called by all who knew him), I witnessed first-hand his passion for flight, his relentless innovative spirit, and the power of his convictions. The most visible legacy from BZ is certainly the benefits of flight envelope protection enabled by Fly-By-Wire (FBW) technology on commercial jet aircraft.
BZ believed that this step change would significantly reduce the risk of loss of control in-flight. The FBW technology was thus first introduced on the Airbus A320 and it is the baseline for every Airbus aircraft produced since. Beyond the Airbus fleet, it is the industry standard today for all new aircraft types.
The facts demonstrate BZ’s vision was absolutely correct, that FBW would significantly reduce the accident rate . Indeed, aircraft with flight envelope protection enabled by FBW technology that belong to the current fourth generation of commercial jets have an impressive record. Today there are around 15,500 in operation, with 11,600 (or 75%) of which are Airbus FBW aircraft. Fourth-generation aircraft
have completed more than 212 million flights and accumulated over 500 million flight hours (172 million flights and 375 million flight hours by Airbus aircraft) over the last 33 years.
This has resulted in a historically low rate of 0.04 fatal accidents per million flights (10-year moving average) compared with the rate of 0.15 for the previous third-generation aircraft without FBW. To follow on from BZ’s focus on the reduction of accidents caused by loss of control in-flight (LOC-I), the current LOC-I accident rate 0.01 for fourth-generation jets is a seven-fold decrease when compared with the rate of 0.07 LOC-I accidents per million flights for third-generation jets.
More than thirty years on, we can reflect on the occasions when persistence over the resistance to change required the characteristic tenacity of someone like BZ, to win over the sceptics and gain support for his vision. The foundations for aviation to make a leap forward in safety are often laid by such visionaries. It is then our duty to constantly reinforce their legacy through collaboration across our industry, and through the implementation of incremental safety improvements on our aircraft and for how they are operated.
I join my Airbus colleagues, and together with so many across our industry, in paying tribute to Bernard Ziegler - a true pioneer and inspiration for aviation safety.
Chapeau bas Bernard

Bernard Ziegler joined Airbus as its chief test pilot in 1972 and he flew the first flight of the first A300. The programme later became an early testbed for FBW which transfers the pilot’s commands to the aircraft via digital signals. FBW provides significant benefits through commonality, improved flight safety, reduced pilot workload, fewer mechanical parts, and real-time monitoring of all aircraft systems.
He also flew the A310, A320 and A340-200. In June 1993, Ziegler participated in the longest flight ever undertaken by a civil aircraft, when an A340-200, dubbed the “World Ranger”, flew around the world from Paris with just one stop in Auckland in just over 48 hours. Up until his retirement in December 1997, Ziegler was Airbus Senior Vice President of Engineering.

纪念贝尔纳·齐格勒
Section titled “纪念贝尔纳·齐格勒”在每一个航空时代，总有一些人凭借坚定的信念开创一种理念，使整个行业从中受益。我曾在贝尔纳·齐格勒（他被所有认识他的人称为“BZ”）手下工作，亲眼见证了他对飞行的热情、永不满足的创新精神，以及他信念的力量。BZ 最显著的遗产，无疑是商用喷气式飞机上电传操纵（FBW）技术所带来的飞行包线保护功能。
BZ 相信，这一技术突破将显著降低飞行中失去控制（LOC-I）的风险。因此，电传操纵技术首先在空客 A320 上应用，并成为此后每架空客飞机的基准配置。除空客机队外，电传操纵如今已成为所有新机型的事实行业标准。
事实证明，BZ 的远见完全正确——电传操纵将大幅降低事故率。确实，采用电传操纵技术实现飞行包线保护的当前第四代商用客机有着令人瞩目的安全记录。目前约有 15,500 架在役，其中 11,600 架（占 75%）为空客电传操纵飞机。在过去 33 年中，第四代飞机已完成超过 2.12 亿次飞行，累计飞行超过 5 亿小时（其中空客飞机完成 1.72 亿次飞行，累计 3.75 亿飞行小时）。
这带来了历史最低的事故率——每百万次飞行 0.04 起致命事故（10 年移动平均值），而此前不具备电传操纵的第三代飞机这一比率为 0.15。延续 BZ 对降低飞行中失去控制（LOC-I）事故的关注，第四代喷气式飞机当前的 LOC-I 事故率为 0.01，与第三代喷气式飞机每百万次飞行 0.07 的 LOC-I 事故率相比，下降了七倍。
三十多年后的今天，我们回望那些时刻——在变革阻力面前坚持己见，需要的正是像 BZ 这样的人物所特有的坚韧，以说服质疑者并获得对其理念的支持。航空安全实现飞跃的基础，往往是由这样的远见者所奠定。而我们的责任是通过行业内各方的协作，通过在飞机及其运营方式上持续实施渐进式的安全改进，不断强化他们留下的遗产。
我与空客的同仁们，以及行业内众多同仁一起，向贝尔纳·齐格勒致敬——他是航空安全领域真正的先驱者和灵感源泉。
谨致敬意，贝尔纳

贝尔纳·齐格勒于 1972 年加入空客，担任首席试飞员，并执飞了首架 A300 的首飞。该项目后来成为电传操纵技术的早期试验平台——电传操纵通过数字信号将飞行员的指令传输至飞机。电传操纵带来了显著优势，包括通用性提升、飞行安全改善、飞行员工作负荷降低、机械部件减少，以及对所有飞机系统的实时监控。
他还执飞了 A310、A320 和 A340-200。1993 年 6 月，齐格勒参与了一项民用飞机史上最长的飞行——一架被昵称为“全球卫士”的 A340-200 从巴黎出发，仅在奥克兰停留一次，在 48 小时多一点的时间内完成了环球飞行。直至 1997 年 12 月退休，齐格勒一直担任空客工程部高级副总裁。
