Edit Summary Request
I have noted that you often edit without an edit summary. Please do your best to always fill in the summary field. This is considered an important guideline in Wikipedia. Even a short summary is better than no summary. An edit summary is even more important if you delete any text; otherwise, people may think you're being sneaky or even vandalizing. Also, mentioning one change but not another one can be misleading to someone who finds the other one more important; add "and misc." to cover the other change(s). Thanks! -- Kukini 22:03, 10 August 2006 (UTC)

I believe I have summary for all of my edition. Please check again.--Natasha2006 17:15, 3 April 2007 (UTC)

License tagging for Image:Airfoil-parts.jpg
Thanks for uploading Image:Airfoil-parts.jpg. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:
 * Image use policy
 * Image copyright tags

This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Media copyright questions. 16:06, 3 April 2007 (UTC)

Tagging for categories
You added a category to runway incursion, but put a colon before the word "Category". That is not the way a category tag in an article is formatted. Also, please check the exact wording and capitalization of a category (I had to change "Air Safety" to "Air safety" for it to work) and its location (at the end of the article). Thanks for helping!-- Orange Mike 15:28, 20 June 2007 (UTC)

Operational errors/Deviations
Hello there Natasha, I saw your test page with this title. It would probably be better for you if you drafted pages in your own user space, such as User:Natasha2006/Operational errors/Deviations for example. This is away from main space and you can edit to your heart's content without being bothered by people threatening to delete your work in progress! You can then transfer the article to main space once it's finished just by changing its name. Let me know if you need help with this, Best wishes, Kim Dent-Brown   (Talk to me)  14:38, 21 June 2007 (UTC)

Course (navigation)
Hi,

I am an ex- Member of the ICAO Obstacle Clearance Panel (now renamed as the Instrument Flight Procedures Panel) and retired, but recruited as an adviser to another Panel Member.

This problem arose because ARINC 424 have 'stolen' the term "course" to define legs with undefined start or end points - the "Course to altitude (CA)" leg and the "Course to Fix (CF)" leg. These leg types arise on takeoff when the autopilot is not engaged until 400 ft, and the aircraft has already been affected by wind and speed changes. It means the aircraft flies in a specified direction from wherever it is when the autopilot is engaged.

It ws then decided to define "course", which is where all went wrong.

The real solution is for ARINC to change the term to something like UA and UF meaning "unspecified point to altitude/fix". However they are not receptive to this suggestion.

I suggest appropriate definitions for the three navigation terms could be:

Course. The projection on the earth’s surface of the theoretical path of an aircraft neglecting the effect of wind, the direction of which path at any point is expressed in degrees from North (true, magnetic or grid). See also “track” and “heading”.

Heading –The direction in which the longitudinal axis of an aircraft is pointed, usually expressed in degrees from North (true, magnetic, compass or grid). See also “course” and “track”.

Note. In navigation, winds are usually given in degrees true, therefore the heading to fly a desired track is usually the course adjusted for magnetic variation and compass correction (see also “course” and “track”)

Track –The projection on the earth’s surface of the path of an aircraft, the direction of which path at any point is usually expressed in degrees from North (true, magnetic or grid). See also “course” and “heading”.

The above definitions for heading and track from existing ICAO definitions. I have added the one for "course", the notes and the cross references.

There may be a need for another definition - the magenta line on the new glass cockpit displays - the "track made good", as opposed to just "track", which should then become "required track". However, the "course" is not the track made good, but that needs further explanation.

Any comments so far?
