Slipstream from a glider tug

[edit]

Interesting! The FAA diagram clearly shows the wake from the wingtips, but I can counter with the BGA's Instructor Manual and Ken Stewart's "The Glider Pilot's Manual" ISBN 1-8433-6078-0, both of which attribute at least some of the turbulence to the propeller. I have amended Gliding to be ambiguous until I can consult a few more people. JMcC 10:40, 25 November 2006 (UTC)[reply]

I agree that wake turbulence from a heavy aircraft is a big issue. Controllers give 737s a short delay so they can land after 747s. At Lasham Airfield we get a few airliners coming and going each week and if we are landing at about the same time, they get a very wide berth. However for small aircraft that are not rotating/flaring, it should be a much smaller effect. The club's AGM distracted me so I was not able to ask on Saturday.

Hi, I am not disgreeing; I just don't know. Yes, we have to box the wake as well. I will ask around about its source. JMcC 08:25, 28 November 2006 (UTC)[reply]

Hello again, I asked someone who should know. He got a first class degree in aeronautical engineering from a top British university (Imperial College), he is the training captain for a large airline, a tug-pilot and a fellow gliding instructor. His reply was:
Does the FAA know anything about aviation? There will be some vortices from the tug but the vortices are weak for a low aspect ratio wing. The prop wash would be a much larger contributor. It may be possible to establish an energy balance to deduce the relative contribution
Engine power = rate of change of potential energy + form drag x speed + induced drag x speed + power lost on propwash
Induced drag coefficient = lift coefficient ^2/ Pi /Aspect ratio
I will leave you to do the sums!
Pete's idea of 'sums' usually involves differential equations. He knows what he is talking about. JMcC 08:26, 30 November 2006 (UTC)[reply]

List of notable glider pilots

[edit]

There is a proposal to delete the List of notable glider pilots. Please register your opinion on Wikipedia:Articles for deletion/List of notable glider pilots. I think it is an interesting list and useful when publicising the sport. JMcC 09:36, 1 August 2007 (UTC)[reply]

Michigan Wikipedians

[edit]

Greetings Nbach! I noticed that you made mention of the University of Michigan or Ann Arbor on your userpage. If you are a current student, faculty, or other affiliate at the University of Michigan, I would like to welcome you, on behalf of the Michigan Wikipedians, to our next weekly meeting on Monday September 30 (and every Monday thereafter). The meetings are held at 8:00 PM (EDT) in the University of Michigan Shapiro Library, room 4041. New and experienced editors alike are most welcome. Do not hesitate to leave me a message if you have any questions, and feel free to stop by the MWiki talk page. The Michigan Wikipedians are excited to meet you!

Greetings Recent Changes Patrollers!

This is a one-time-only message to inform you about technical proposals related to Recent Changes Patrol in the 2016 Community Wishlist Survey that I think you may be interested in reviewing and perhaps even voting for:

  1. Adjust number of entries and days at Last unpatrolled
  2. Editor-focused central editing dashboard
  3. "Hide trusted users" checkbox option on watchlists and related/recent changes (RC) pages
  4. Real-Time Recent Changes App for Android
  5. Shortcut for patrollers to last changes list

Further, there are more than 20 proposals related to Watchlists in general that you may be interested in reviewing. (and over 260 proposals in all, across many aspects of wikis)

Thank you for your consideration. Please note that voting for proposals continues through December 12, 2016.

Note: You received this message because you have transcluded {{User wikipedia/RC Patrol}} (user box) on your user page. Since this message is "one-time-only" there is no opt out for future mailings.

Best regards, SteviethemanDelivered: 01:12, 8 December 2016 (UTC)[reply]

Please help with usability testing

[edit]

Hello! The mw:Anti-Harassment Tools team is running a usability test to find out how and where IP addresses are used when patrolling wikis, particularly when patrolling RecentChanges. This could include New Pages or RecentChanges patrol. We want to see your patrolling process and get your views on some prototypes. Getting your perspective would be really helpful to us at this stage of the process. If you’d like to help, and have 30 minutes to spare, please fill out this Google form with your details: https://docs.google.com/forms/d/e/1FAIpQLSfjYyRNGMkO4_TdNOgG4qmK9cp9YOKzM4GFO5pTd_bEcu23YQ/viewform


For the purpose of the tests we’ll be using Google Forms for recruitment, and UserTesting.com to conduct the actual tests. Please review the privacy statement and release form in https://docs.google.com/document/d/1ijmwrIoNO0W1p_zfFU1LBf3_6mFF53kUUFy1L_DCUKc (Google docs link)

Thank you,
