I'm removing the sentence about 'ETOPS may require testing in remote areas' - as far as I know, ETOPS operations are permitted based on meeting training, equipment and reliability standards, and no ETOPS testing is conducted. Cerireid (talk) 12:35, 5 August 2008 (UTC)[reply]

There are other. I think they are notable enough, huh? --Yuriy Lapitskiy ~ 14:17, 22 December 2007 (UTC)[reply]

Why was the STC redirected to here? Doesn't seem like wiki would want both discussed in same2busy2chat (talk) 03:43, 23 May 2008 (UTC)2busy2chat[reply]

Bad grammar

The second sentence makes no sense. — Preceding unsigned comment added by 173.246.1.87 (talk) 05:08, 29 July 2013 (UTC)[reply]

The article included a reference to another WP article entitled, Standard Airworthiness Certificate". The definition for the latter may not be applicable in the US, refers to "states" which appears to be a reference to "Nation State", not to the meaning it has in the US. Refering to it, didn't seem necessary after making changes so I removed the reference. Kernel.package (talk) 14:10, 8 August 2013 (UTC)[reply]

These paragraphs should be moved to another article. The processes followed in the US is essentially the same as in other countries. The prevailing legislative and enforcement bodies may differ. Another factor to consider is that only military in the U.S. is subject to different standards than non-mil. Also, NASA is subject to these same rules, as are Telecommunications satellites. That is: They apply to everything that's in the air, and that we hope either stays in the air or falls to the ground in a predictable way. Kernel.package (talk) 14:28, 8 August 2013 (UTC)[reply]

What is "TCDS"? (See article for reference to the acronym). Kernel.package (talk) 14:43, 8 August 2013 (UTC)[reply]

Type Certificate Data Sheet. Dolphin (t) 00:55, 9 August 2013 (UTC)[reply]

Thanks for drawing this acronym to our attention. I have changed the statement so it now says an airworthiness certificate is issued if an aircraft conforms to its type design, which is the correct terminology. A Type Certificate Data Sheet is not a document or a standard to which an aircraft can "conform". Dolphin (t) 05:45, 9 August 2013 (UTC)[reply]

The Type Certificate just ensures that all subsequent production aircraft produced conform to the same design as that of the sample aircraft subjected to examination, and are manufactured by the same method.

The type certification process was a result of World War I, where large numbers of military aeroplanes were produced, often by non-aviation companies - such as furniture companies - some of whom produced aircraft that were shoddily-built, often with "improvements" incorporated to ease manufacture, such as using an alternative material, that were detrimental to the safety of the aeroplane and its crew. This led to a number of deaths. The certificating process was introduced to make sure that aircraft being flown were actually safe, or as safe as was reasonably possible at the time.

The certification of a type ensures that once a certificate has been issued a manufacturer cannot significantly change the design of the type or method of manufacture without the inspection and approval of a qualified and independent third body. — Preceding unsigned comment added by 95.150.18.150 (talk) 10:25, 21 November 2016 (UTC)[reply]

Here are some Royal Aeronautical Society podcasts of interviews recorded in the 1990s with D. P. 'Dai' Davies, head UK ARB test pilot from 1949 to the 1980s who tested a large number of civil aircraft for UK type certification including the 707, 747, and Concorde:

[1] Comets, Boeing 707, Britannia & Brabazon

[2] Boeing 747, the Trident, VC10, One Eleven & the Boeing 727

[3] Concorde and the V-bombers

Dai Davis was also the author of a popular airline pilot's book, "Handling The Big Jets". — Preceding unsigned comment added by 95.149.53.134 (talk) 08:35, 11 March 2020 (UTC)[reply]
