Here is my take on it: 1) Some Advisory Circulars contain the words "Material in this AC is neither mandatory or regulatory". The AIM Preface contains this wording: "This publication, while not regulatory, provides information which reflects examples of operating techniques and procedures which may be requirements in other federal publications or regulations. It is made available solely to assist pilots in executing their responsibilities required by other publications." So one could logically conclude that an a priori failure to comply with an AC or the AIM is not "really illegal". 2) Now let's shift into the real world. Suppose a pilot is involved in an incident, ramp check,** or accident wherein an AC or the AIM has been violated and the FAA decides to suspend or revoke the pilot's license. The pilot appeals to an NTSB judge and the FAA cites 14 CFR Sec. 91.13 (a) "....No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another." and 14 CFR Sec. 91.103 "Preflight action. Each pilot in command shall, before bginning a flight, become familiar with all available information concerning that flight." to support their case. How do you suppose the NTSB judge is going to rule? OC **PS: I recently sat in an audience and listened to the head ASI (Aviation Safety Inspector) from an FAA FSDO tell how she had been itching for a long time to run a ramp check on a hot air balloon (the "notch in my pistol grip" syndrome) and how disappointed she was that she could not find a thing wrong when she finally got her chance to inspect one. I have also heard stories (second hand) of ASI's waiting at an airport with a low ceiling or visibility and interrogating pilots that have just landed.With a mind set like that among some FAA employees I am not willing to violate an AC or the AIM without a very deliberate "risk versus reward" examination of the situation.

Transmission remains OK but the reception keeps breaking up. The No 2 com doesn't do it so I've ruled out headsets and audio jack. I've tried swapping radios and that doesn't help Any suggestions how best to troubleshoot this. Could it be the connections from the radio to the audio panel or in the audio panel itself? Thanks ________________________________ Message 3 _____________________________________ Time: 09:42:42 AM PST US From: James Freeman Subject: Re: Avionics-List: Toruble shooting Radio --> Avionics-List message posted by: James Freeman This symptom is fairly common at high speeds and/or power settings, and can be caused by breaking squelch on the intercom. It is especially common if you have an unused headset plugged in, but the pilot's mike can break squelch too. Try turning off your intercom to see if this addresses the problem. My apologies if you've already thought of this.

The complete Avionics-List FAQ including these Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/Avionics-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator ****************************************************************************** Avionics-List Usage Guidelines ****************************************************************************** The following details the official Usage Guidelines for the Avionics-List. You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the Avionics-List in the manner described below may result in the removal of the subscribers from the List. Avionics-List Policy Statement The purpose of the Avionics-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occassional posts by vendors or individuals who are regularyly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.]
