The progress of female pilot training is an important indicator of the maturity and systemization of the shipborne aviation talent selection and training system, a military affairs expert said. Smears by some foreign media about China's pilot training capabilities are, in essence, a projection of the West's own anxieties over talent shortages, the expert added.
"Night landings are tougher than I imagined. The entire sea is pitch black. It's hard to tell where the sea ends and the sky begins. It's very easy to become disoriented," said Han Meng, a female trainee pilot at the Naval Aviation University, in the CCTV News video.
"Completing today's landing mission has given me a clearer understanding of my own abilities. I'm about to graduate, and I feel more confident about heading to my post and carrying out various maritime and far-sea missions I'll be assigned," she added.
The CCTV News report showed that the assessment featured a Z-8 helicopter landing on the aft flight deck of a vessel.
CCTV reported on Friday that the first batch of female shipborne pilot trainees had all recently passed their daytime shipborne landing qualification assessments. Shipborne landing is a critical milestone in a shipborne pilot's development, often described as the "certificate" to real naval aviation. Passing this assessment marks a significant step in the PLA Navy's efforts to cultivate female shipborne aviation talent.
All pilot trainees, regardless of gender, must meet the same rigorous physical and psychological standards required for shipborne aviation. The successful qualification of these female trainees demonstrates that the selection and training systems are capable of identifying and developing top-tier talent based on capability, not gender, Zhang Junshe, a Chinese military affairs expert, told the Global Times on Sunday.
In recent years, the PLA Navy's shipborne aviation talent development has entered a new phase of system-of-systems operations, transitioning from "able to fly and land on ships" to "able to fight and operate jointly," PLA Daily reported on April 22.
Under the synchronized training objectives of developing pilots, combatants and commanders, new pathways for talent cultivation are being explored, including growth opportunities for shipborne fighter and helicopter pilots. Training programs are being optimized across all elements, support resources coordinated across all domains, and implementation advanced across all processes, forming a systematic, integrated talent development framework.
Zhang also mentioned that foreign media outlets have hyped claims of a "pilot shortage" in China or that "talent development cannot keep pace with equipment delivery." Such claims are largely based on selective data comparisons and misunderstandings of China's aviation development, essentially reflecting the West's own anxieties about talent.
First, foreign media outlets often simply compare the total number of licensed pilots in China with that of the US, ignoring differences in population size, the prevalence of aviation culture and historical development. China's nationwide selection process draws from a vast pool of candidates, ensuring high overall pilot quality and building a strong reserve of aviation talent, Zhang noted.
In July, the PLA Navy's 2026 pilot recruitment process was successfully completed. The average college entrance examination scores of admitted pilot trainees reached a record high. In recent years, through extensive outreach and publicity campaigns, enthusiasm among young applicants has continued to grow, with the recruitment pool expanding year by year.
The Navy's recruitment authorities have established carrier-based flight aptitude assessment platforms, introduced new testing technologies including virtual reality and biofeedback, and improved the comprehensiveness and accuracy of flight aptitude evaluations, said the PLA Navy.
Meanwhile, China has established a diversified training system encompassing academy training, airline-commissioned training and civilian supplementary pathways. Through general aviation development, China is expanding its civilian talent reserve and gradually narrowing the gap with leading aviation nations, the expert said.
Moreover, modern air warfare is a complex system undertaking, relying not only on the number of pilots but also on comprehensive system-of-systems support across strategic early warning, electronic warfare, command communications and ground maintenance. The leapfrog development of China's aviation equipment is built on overall improvements in comprehensive national strength and the aviation industrial system, rather than a simple linear increase in pilot numbers, Zhang added.
。这家总部位于马萨诸塞州弗里明翰的公司刚刚推出了一项名为“安静舒适”的新技术，该技术声称能够测量车辆振动以消除日常驾驶中的噪音。Bose指出，随着汽车的重量越来越轻，电动汽车越来越多，这种降噪技术可能会受到越来越多的关注。

二 | 坐在安静的电动汽车里的司机比坐在嘈杂的内燃机车更容易受到道路噪音的影响。Bose将这项技术定位为展望未来，因为道路上会有更多的电动汽车。那么它是如何工作的呢？传统的车辆降噪方法包括使用更厚的绝缘材料或专用轮胎，以尽量减少在崎岖不平的道路上行驶时产生的噪音。但这些方法增加了车辆重量，降低了燃油效率。Bose使用加速度计、专有的信号处理软件、麦克风和汽车内置音响系统的组合来“电子控制不需要的声音”。Bose说：安装在车身上的加速度计使Bose算法能够连续测量产生噪音的振动。然后，利用该信息计算出通过车辆扬声器传输的消声信号，以降低目标噪声。

三 | 放置在驾驶室中的麦克风监控残余噪音水平，允许系统调整控制信号以优化不同道路上的性能，并随车辆老化自动调整。虽然Bose有一个非常著名的降噪耳机，但它的车是一个非常不同和复杂的环境。该公司指出，自2010年以来，其汽车部门已向汽车制造商提供了ehc，这是一项用于降低劣质发动机噪音的高目标技术。Bose表示，在降噪技术的发展过程中，将与汽车制造商合作，将该技术直接安装在汽车生产过程中，首批支持安静舒适的汽车将于2021年底投产。视频：（如果移动客户端用户无法观看视频，请单击此处查看）。
