Editing and Uploading Process[edit]

Aircraft 3-Views[edit]

PDF files are downloaded and then uploaded to the image extract tool on PDF-Online.com. The metadata of the result is then checked to determine its dpi. The file is opened in GIMP with the correct dpi entered in the import dialog box. The 3-view is then cropped to remove all extraneous content so only the drawing itself remains. (In cases where the three views are spread across two pages, prior to cropping the views are aligned on the aircraft centerline using a guide. The vertical spacing is determined by measuring the distance between the lowest point on the upper view and the highest point on the lower view of the two views on the same page. Identical spacing is then applied between the highest or lowest point on one of the two views on one page and the third view on the other. The two pages are then merged together.) The image is exported from GIMP as a PNG and uploaded. (By uploading the cropped, but otherwise unredacted version first, it creates a master copy that can always be reverted to should mistake be made in one of the subsequent edits.) The format of the aircraft's manufacturer, designation (including variant), and nickname used in the file name is as depicted on the document the image was taken from and may not be the most common form. The second portion of the file name depends on the format of the image itself (e.g. line drawing or silhouette). After the initial version is uploaded, the image is grayscaled and reuploaded. It is then edited a third time to remove any imperfections or partially cropped content. This is performed by using a fuzzy select tool or select by color tool set to a threshold of 20 to 30 is on any white background areas to highlight the imperfections and remove any minor gradations in tint. A few minor changes are made with future conversion to vector format in mind. These mostly involves the elimination of one pixel spaces and the creation of gaps to separate elements such as individual characters of text that could cause problems for an automatic tracing program. Similarly, creation of a contiguous white area allows future users to more easily use a fill tool to color the drawing by reducing the number of separate areas that need to be clicked on. The revised version is again uploaded. If necessary, a the image is deskewed and a fourth version is uploaded. (Multiple versions are uploaded so that they can be reverted to if a mistake in editing is found later.) When the upload process is complete, the resulting image is then placed on the relevant article in the specifications section immediately under the section header as a right-aligned frameless thumbnail between 300 and 600 pixels depending on size.

Logos[edit]

The sources are searched by using character strings that usually include the name of the company excepting the last word, which indicates the company's type (e.g. company, corporation, or incorporated). An example of each of the search results is opened in a separate tab. They are then compared until the best version is determined according to scan resolution, size, "cleanliness", and other factors. The image is then screenshotted using Windows Snipping tool and saved to the desktop. The file name is the name of the company as represented in the advertisement (which may or may not be the most well known formulation of the company's name) or the name of the specific product. If two or more versions of the logo with the exact same name are present, then they are differentiated by placing the year of the advertisement in parentheses at the end of the file name. If two or more versions of the logo with the exact same name and from the same year are present, then they are numbered sequentially starting with the one earliest in the year. The files are then opened in GIMP where they are edited. The images are cropped to within 4-5 pixels of the most extreme points of the logo according to the most drastic change in contrast between two sets of pixels. (This does two things: 1. If there is any question as to where the changeover occurs due to a gradual change in color, it leaves a buffer that includes. 2. It creates a useful margin so that the lines don't cause any confusion by being right up against any other content in whatever situation they are used and aren't immediately at the edge of the screen if viewed in isolation.) If the image includes extraneous markings – such as those from parts of the advertisement that are not part of the logo – they are then hidden with the clone tool. When uploaded the images are placed into one of four categories: logos of aircraft manufacturers, logos of aircraft engine manufacturers, logos of aircraft propeller manufacturers, or logos of aircraft accessory manufacturers. If they exist, they are also placed into either the relevant company or specific product category as well.

Aids for Determining Status of Marking[edit]

It is not always clear whether a marking used in an advertisement is actually a logo, or just a fancy font. Therefore, it can be helpful to look for either manuals from the company to check whether they use the marking. Alternatively, a search of USPTO.Report may be useful. Finally, the Official Gazette of the United States Patent Office, which USPTO Report appears to draw from, is a more manual method of searching for trademark applications.

This subsection was created not because these aircraft are to be compared, but because they share the common characteristic of being produced post-1977 and operated by the U.S. military. Therefore, while any manuals normally would have been automatically copyrighted, the 3-view drawings from the military manuals would still be public domain. Said manuals may be available from Air Force e-Publishing or as NATOPS flight manuals from Secretary of the Navy.

Note that many of the drawings found on various websites (such as Aircraft Systems Tech and Flight Mechanic) are copied from the Aviation Maintenance Technician Handbook, or similar Federal Aviation Administration publications. Further note that, in the original PDF file published by the FAA, the drawings appear to be in vector format.
