 * 1) Citations are not supposed to be in the lead as it is supposed to be a summary of the article.
 * 2) * I can remove them, but I am waiting for your response as that seems to contradict WP:LEADCITE. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 3) **Generally, citations are only supposed to be in the lead for the points you mentioned or if that lead information is unique in the entire article. The lead is meant to be a summary of what is to come in the article. I have been told this in past GAN's. Please explain your reasoning of why you placed citations in the lead.

 * 4) ***This is what WP:LEADCITE says: The necessity for citations in a lead should be determined on a case-by-case basis by editorial consensus. Complex, current, or controversial subjects may require many citations; others, few or none. A lot of people (myself included) often only read the lead, and their main use of WP is to find sources. The material presented is not patently obvious to an average person, like "the sky is blue", and therefore may potentially be challenged. And because the material may be challenged, it requires citations, which I have supplied. Crum375 (talk) 22:06, 2 August 2009 (UTC)
 * 5) In the lead, there are 2 two-sentence paragraphs. Can these be merged with other paragraphs?
 * 6) * Fixed that by moving one short one into the body. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 7) Citation needed for "LFR remained as the main radio navigation system in the U.S. and other countries until it was gradually replaced by the much-improved VHF-based VOR technology, starting in the 1950s."
 * 8) * Done. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 9) The entire Approaches section is uncited. Can citations be added?
 * 10) * Done. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 11) Citation needed for "Modern ADF receivers are small, low cost and easy to operate, and the NDB remains today as a supplement and backup to VOR and GPS navigation, although it is gradually being phased out."
 * 12) * Done. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 13) The sentence "Its eventual replacement, the VHF band VOR navigation system, was virtually immune to interference, had 360 course directions per station, had a visual "on course" indicator, and was far easier to use." is very fragmented and needs to be reworded.
 * 14) * Broke up and reworded. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 15) Citation needed for "Consequently, when the VOR system became available in the early 1950s its acceptance was rapid, and within a decade the LFR was mostly phased out. VOR itself is gradually being phased out today in favor of the far superior Global Positioning System (GPS)."
 * 16) * Done. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * 17) Citation needed for "The following are simulated sounds for the Silver Lake LFR. The range station — located about 10 miles north of Baker, California — would preempt the navigational signals and transmit its Morse code identifier ("RL") every 30 seconds. Pilots would listen to and navigate by these sounds for hours while flying. Actual sounds contained static, interference and other distortions, not reproduced by the simulation."
 * 18) * Done. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * Thank you for your review. It is very much appreciated. Crum375 (talk) 03:47, 31 July 2009 (UTC)
 * I will now pass the article. Dough4872 (talk) 14:37, 3 August 2009 (UTC)

I've modified your text to indicate that L/MF airways are still in use as of 2009 - something that surprised me, but I just discovered it while taking an IFR flight review. There is still at least one LF/MF airway in the continental US (AR3, off the No. Carolina coast) and evidently a couple of dozen in Alaska. I am not clear whether they're still using Adcock Range ground equipment; AR3 appears to be based on an NDB. Excellent article in other respects! 69.225.43.165 (talk) 00:08, 29 August 2009 (UTC) John D. Ruley (jruley@ainet.com)
