PMDG分析 - 事实还是虚构?
在更广泛的飞行模拟社区中,精密手册开发组(PMDG)通常被认为任何模拟平台的运输类飞机插件优质开发商。虽然到目前为止只发布了一款X-Plane产品(DC-6B),但很明显,随着平台的不断发展,该公司将寻求在我们这一方面取得稳定的进展。
因此,详细分析它们的行为将非常有用。大多数酝酿者都会很高兴地承认在这个开发者的公开行动中存在某种“光环”,这基本上会对他们产生一种积极性(可能在今年FSExpo之后不那么多),即使他们要发布现在臭名昭着的PMDG Woodpigeon。但这些人究竟是谁?实际进行测试时,他们的营销如何得以保持?他们的作案手法有一个黑暗的一面吗?那火热的东西究竟是一架“学习水平的飞机”呢?这些是本系列文章将要解决的问题。
PMDG由罗伯特·兰达佐上尉于1997年创立,他在商业航空领域更为人所知,因为他是世纪之交监督波音777在联合航空公司投入使用的关键人物之一。这个高级飞行员职位​​使他能够与波音公司的高级官员建立联系,这对PMDG来说至关重要,因为PMDG是基于ESP平台的研究级客机产品部门的事实上的创始人。
正如公司名称所示,第一批产品不是飞机,而是德国Aerowinx公司独立的747-400模拟器“747 Precision Simulator”的补充手册(其最新版本,具有讽刺意味的是,被认为远远优于最新的PMDG) 747 - 提供X-Plane作为视觉发生器的原生支持,尽管令人目不暇接的是350欧元,相比之下,目前用于P3D的PMDG 747为135欧元。然而不久之后,兰达佐决定自己投资飞机开发,第一架飞机,即已故理查德哈维的飞行模拟器777,“飞!”,于2001年发布。
根据Robert S. Randazzo本人的说法,飞行!系列在PMDG产品设计策略的后续演变中发挥了重要作用。作为第一个具有现实系统和大气模型开箱即用功能的模拟器,我们在最近的X-Plane迭代中开始看到新的Cessnas,例如 - FLY!在消费者飞行模拟方面开辟了新天地。在Harvey 2003年因癌症惨死后,PMDG被迫开始为当时的平台选择Microsoft Flight Simulator 2004创建等效的系统功能。原始的737NG于2003年发布,随后是Beech 1900D,第一个版本747和命运多MD的MD11于2008年发布。在团队内部发生内部冲突后,
这些丑闻被认为涉及MD11 DRM实施的性质上的分歧,这再次听起来太熟悉了。我相信这些分歧很可能导致MD11的发展停止(与官方引用的低销售额相反),以及后来退出销售。目前尚不清楚是谁控制了MD11代码库,PMDG或Kalamaras,这就解释了为什么PMDG希望尽快摆脱MD11而不丢脸。兰达佐一再暗示MD11几乎让他失去了公司,例如,如果卡拉马拉斯在法庭上付出相当大的代价,这是可以想象的 - 考虑到我们现在对他对诉讼程序的感情所知,这并不是不切实际的。也许兰达佐的回忆录有一天会揭晓全部故事?毕竟,这是
随后是MD11,随后是2009年J41的原始版本,这是一个很大程度上实验性的产品,作为2011年发布的B737 NGv2(NGX)的测试平台。此时,PMDG宣布它只会开发大众化产品(由于涉及较低的财务风险,不包括测试产品,因此,最新一代玻璃客机)。这与MD11丑闻以及随后可理解的利润最大化愿望有关。与此相符,NGX推出了“波音引擎”,这是一种模拟软件框架,旨在复制波音玻璃喷气机。该引擎允许PMDG模拟新飞机,同时最大限度地减少编写从头代码的需要。因此,从软件架构的角度来看,NGX开始了公司的现代时代。
波音发动机的功能包括基于物理的电动,液压,气动和热力学物理模型。PMDG在每个新版本中都增加了额外的模块:777(2013)看到了ECL和777 FBW,自动控制器和EICAS逻辑,而去年的747包括新的地面物理以及源自FFS运动提示方程的抖动算法。747-8i / 8F套件将包含模拟波音ANF(机场导航设施)渲染器,用于显示EHSI / ND上的机场地图,以及模拟最新一期的波音电子飞行包(EFB)板载性能工具(OPT)软件和支持Navigraph的Jeppesen虚拟图表剪辑管理,再次复制了实际波音软件的几乎所有功能。
DC6在PMDG的阵容中有点奇怪。该产品最初是为FSX编码的,最初于2016年6月重新开发并发布用于XP10,去年发布了ESP。根据Robert S. Randazzo的说法,它的主要目的是作为确定将玻璃喷气机队带入XP的最佳策略的试验台。然而,由于缺乏对DC-6的X-Plane迭代的更新,而不是ESP版本,这很快导致缺乏官方XP11支持。也就是说,该产品在v11中可以正常工作,但是不能保证飞行和系统模型能够按照PMDG的预期运行。
我们只能猜测缺乏进一步更新的原因,但是看看PMDG未来X-Plane方法的本质将会非常有趣。考虑到其娱乐使用的阴暗法律地位,门槛高度怀疑以P3D为中心的方法,这是洛克希德选择放弃进一步飞行模拟开发后由MS设定的MS限制部分的明确故意法律背驮。
鉴于PMDG在飞行模拟领域的先行者地位,很少有评论者能够真正胜任其评估产品。因此,我们将利用我们的航空专业人员网络来评估他们的营销,产品,公关的所有关键方面,以及他们是否始终应得,模拟,以及归因于他们的优质地位。
我们的第二部分将介绍PMDG的品牌标识以及内部和外部建模的视觉方面。正如我们很快就会发现的那样,作为您的虚拟工作空间,驾驶舱的正确比例和缩放具有突破性的重要性。

以下为原文
Among the wider flight simulation community, Precision Manuals Development Group (PMDG) are usually considered the premium developer of transport-category aircraft addons for any simulation platform. Whilst only having released one X-Plane product so far (a DC-6B), it is obvious that the company will be looking to make stable inroads on our side of the fence as the platform continues to grow.

It will therefore prove useful to analyse their behavior in detail. Most simmers will gladly acknowledge the presence of a certain “halo” in this developer’s overt actions, which essentially projects a cloud of positivity over them (perhaps not so much after this years FSExpo), even if they were to release the now-infamous PMDG Woodpigeon. But just who are these people? How does their marketing hold up when actually put to the test? Is there a dark side to their modus operandi? And what the flaming heck is a “study-level aircraft” anyway? These are the kinds of questions this article series will address.

PMDG was founded in 1997 by Captain Robert S. Randazzo, who, in commercial aviation, is better known for having been one of the key people supervising the entry-into-service of the Boeing 777 at United Airlines at the turn of the century. This senior pilot position allowed him to form connections with high-ranking officials at Boeing, a fact paramount to PMDG having been the de facto founders of the study-level airliner product segment for ESP-based platforms.

As the company name suggests, the first products were not airplanes, but supplementary manuals for the stand-alone 747-400 simulator “747 Precision Simulator” by German company Aerowinx (whose latest version, ironically enough, is considered vastly superior to the latest PMDG 747 -- and offers native support for X-Plane as a visuals generator, albeit at an eye-watering 350€, as compared to 135€ for the current PMDG 747 for P3D). Soon afterwards, however, Randazzo decided to venture into aircraft development himself, and the first aircraft, a 777 for the late Richard Harvey’s flight simulator, “Fly!”, was released in 2001.

According to Robert S. Randazzo himself, the FLY! Series played a major role in the subsequent evolution of PMDG’s product design strategy. Being the first simulator to feature realistic systems and atmospheric models out-of-the-box -- features we have only begun to see in recent iterations of X-Plane with the new Cessnas, for example -- FLY! was set to break new ground in consumer flight simulation. After Harvey’s tragic death from cancer in 2003, PMDG was forced to start creating equivalent systems functionality for the then-platform-of choice, Microsoft Flight Simulator 2004. The original 737NG was released in 2003, followed by a Beech 1900D, the first version of the 747 and the ill-fated MD11, which was released in 2008. Following some internal conflicts within the team, MD11 chief developer Lefteris Kalamaras left PMDG to found his own company, Flight Sim Labs, which, as we know, has itself failed to stay out of the scandal spotlight in recent months.

These scandals are believed to have involved disagreements as to the nature of the MD11’s DRM implementation, which, again, sounds all too familiar. I believe it is quite possible that these disagreements led to the cessation of the MD11’s development (in contrast to the officially cited low sales), as well as its later withdrawal from sale. It remains unclear who controls the MD11 codebase, PMDG or Kalamaras, which explains why PMDG wanted to get rid of the MD11 as soon as possible without losing face. Randazzo has repeatedly hinted at the MD11 nearly having cost him the company, which is conceivable if Kalamaras, for example, settled in court for a considerable sum -- not unrealistic given what we now know about his affections for litigative procedures. Perhaps Randazzo’s memoirs shall one day reveal the full story? It is, after all, the only product from the lineup not to get a remake -- even the Jetstream 41 got one, although it has not yet been released, which poses even further interesting questions about what exactly happened to the MD11.

The MD11 was then followed by the original issue of the J41 in 2009, a largely experimental product that served as the testbed for the B737 NGv2 (NGX) released in 2011. At this point, PMDG announced it would only develop mass-appeal products (that is, latest-generation glass airliners), due to the low financial risk involved, excluding test products. This had everything to do with the MD11 scandal and a subsequent, understandable desire for profit maximisation. In line with this, the NGX introduced the “Boeing engine”, a modular software framework designed to replicate Boeing glass jets. The engine allows PMDG to simulate new aircraft while minimising the need to write de novo code. Thus, from a software architecture viewpoint, the NGX began the company’s modern era.

The capabilities of the Boeing engine include physically-based electric, hydraulic, pneumatic and thermodynamic physics models. PMDG has gone on to add additional modules with each new release: the 777 (2013) saw the ECL and 777 FBW, autocontroller and EICAS logic whereas last year’s 747 included new ground physics as well as headshake algorithms derived from FFS motion cueing equations. The 747-8i/8F package will contain a simulation of the Boeing ANF (Aerodrome Navigation Facility) renderer for displaying airport ground maps on the EHSI/ND, as well as a simulation of the latest-issue Boeing electronic flight bag (EFB) with Onboard Performance Tool (OPT) software and Jeppesen virtual chart-clip management supporting Navigraph, again replicating nearly all features of the actual Boeing software.

The DC6 has been a bit of an oddball in PMDG’s lineup. Initially coded for FSX, the product was initially redeveloped and released for XP10 in June 2016, with a subsequent ESP release last year. According to Robert S. Randazzo, its chief purpose was to serve as  a testbed for determining the optimum strategy for bringing the glass-jet fleet into XP. There has, however, since been a notable lack of updates to the X-Plane iteration of the DC-6, as opposed to the ESP version, which quickly led to the absence of official XP11 support. That said, the product does work in v11, but the flight and systems models cannot be guaranteed to function as intended by PMDG.

We can only conjecture as to the reason for a lack of further updates, but it will be extremely interesting to see the nature of PMDG’s approach to X-Plane in the future. Threshold highly doubts a P3D-centric approach given the shady legal status of its entertainment use, a clear intentional legal piggyback on Lockheed’s part of MS-imposed restrictions set by MS after it chose to abandon further flight simulation development.

Given the forerunner status of PMDG in the flight simulation space, few reviewers are truly competent enough to assess its products. We will thus be harnessing our network of aviation professionals to evaluate all key aspects of their marketing, products, PR and whether they consistently deserve, simulation-wise, the premium status attributed to them.

Our second part will be about PMDG’s brand identity as well as the visual aspects of internal and external modeling. As your virtual workspace, correct proportionality and scaling of the flight deck is of deal-breaking importance, as we will soon discover.

如果我有时间有团队有飞机确切的技术资料,我也可以做得出来。类似于“波音引擎”我做电力机车的时候脚本也是这样的,几辆车都可以移植,只要是直流机车都可以,只是改做HXD的时候才需要写HXD版本的。。
