# Do bluetooth aviation headsets and/or music negatively affect safety?

• Do bluetooth aviation headsets and/or music negatively affect safety? Brian Wheeler

I'm in the process of getting my private pilot's license, and I've come to the point where it's probably time to think about buying a headset.

As I understand it there are a few options ranging from a standard mic and speakers, to passive noise cancellation, active noise cancellation, and even bluetooth for use with iPhones/MP3 players, which I think is awesome, however I'm concerned about distraction while flying.

Has listening to music and/or noise cancellation been at all shown to increase pilot error?

My main concerns are

1. What if I have a noise cancelling headset on, and the engine undergoes detonation, or what if the aircraft does something I should be alarmed about based on auditory cues that I can't hear?

2. Same situations as above, but even worse because I'm rocking out to some sweet tunes, is there the possibility that having music will exacerbate the aforementioned issues, or what if ATC comes on, and I hear them, but I don't register what they say because I was jamming to some Kenny Loggins?

Additionally, are commercial pilots permitted to use bluetooth headsets for phone calls? For music? Do crash statistics indicate that music and flying leads to more pilot-error? It certainly can't help...

• Let me share some of my experiences with my active noise cancelling headset when flying piston aeroplanes. First, if you fly multi-engine and the props are not synchronizing automatically everyone without active noise cancelling on board will definitely hate you - you really don't hear that horrible sound which is really comfortable especially while practicing engine failures. Beside of this you are still able to hear everything whats going on. It there are abrupt noises or warning horns you'll be able to hear them. Active noise cancelling can really help you to be concentrated and allows you to hear ATC much clearer than before. This is especially valuable on crowded frequencies or while getting an ATIS, but also being under radar control/services.

Listening to music while flying is a different story. It can be distracting and I'm still cautious using this great feature. On long x- countries it's really amazing to have it while I would for sure turn it off approaching a busy airport. It can definitely influence your ability to focus on the flight, but sometimes I think even on a positive way keeping you in a good mood.

The best you can do is to try it, because everyone is different. Find the best settings for your self and make your own experiences. There are aviation shops which will give you a headset to try it, otherwise you can ask friends who may have one, or order via the internet and if you don't really feel comfortable with the one you ordered you can return it during a specified period of time.

One last and really important point: If you tested it and decided to spend some extra money on a high-end headset look for special offers. There are a bunch of websites where you can safe a lot of money. I would always check if you still have the original guarantee.

• To my knowledge there are no studies correlating ANR (or good quality passive) headsets with an increase in pilot error, but a several have been done on noise fatigue. There's even an old FAA advisory circular on the subject which basically boils down to "Multi-hour flights listening to the engines drone on and on will make the pilot cranky and error-prone" - so from that perspective any good-quality headset is a safety enhancement.

As far as missing auditory cues because of ANR (things like the stall warning, funny engine noises, etc.) it's generally not a concern: ANR headsets are good, but they're not THAT good. Because of the way ANR works sudden sounds will cut through. You'll miss "long-term noise" (like the beat frequencies Falk mentioned from unsynchronized propellers), but you're not likely to miss anything safety-critical.
(One notable exception: ANR headsets are good at cutting out wind noise, so if you have a partially unlatched door you won't hear that.)

What you will notice with ANR headsets is that when the battery dies things get loud - sometimes louder than cheap passive headsets. Carrying extra batteries is a must with ANR headsets since having your noise reduction go away in the middle of a flight would be somewhat unpleasant.

As far as music, that's a mixed bag. Much like having a CD playing in your car, I don't believe it's a significant safety impact unless you're being irresponsible with it (blasting it at a volume that drowns out everything around you, or rocking out when you should be watching for traffic).

Additionally, all the intercoms and headsets I've seen give the com radio priority, and will either cut out or substantially mute the music input when there's radio traffic. This makes you less likely to miss radio calls, but it also makes listening to music in the plane an absolutely DREADFUL experience (in the northeast where I am there's always somebody talking on the frequency - if you hear half of the song between the radio cutting in it's a good day).

I personally find the distraction from the music muting/unmuting to be more of an issue than boredom from not having music in the first place (if you're that bored you can always look out the window, or tune a local CTAF frequency and listen to the antics), but your experience may vary substantially if you're in an area where the radio is quieter.

Policies for commercial pilots would vary depending on the operation, but for airline pilots using your personal cell phone is forbidden, and before it was forbidden by the FAA it was usually prohibited by the airline.

Part 91 operations (a ferry flight, or a crop duster spraying the local fields) wouldn't be subject to that restriction though, and making a phone call or listening to music would be permissible under the FARs. With all the studies on the negative safety effects of using a cell phone while driving I wouldn't recommend the phone call, but I imagine crop dusting is more fun if you have some music to listen to…

• I enjoy tracking air traffic at my local KORD. I listen on LiveATC and use my private virtual radar setup to get "real-time" traffic info. I understand which instructions need to be read back by the pilots per this question however on more than one occasion I don't hear read back on critical vector info on departure, despite the visual confirmation of instruction (pilot making proper vector... and that's why I don't hear reply, however on approach side much bigger distances are heard in my area) Thank you I did verify that indeed the aircraft that I don't hear read back from receives

• These are calculations which I use to know when to descend and the Rate: Multiply the ALT of feet to lose by 3 and $Groundspeed\div2\times10$ will give you your required rate of descent for a 3° glide slope. For example: FL350 to FL100 => 25,000 ft down $25\times3=75$, so start at 75 nm GS = 320 kts => $320\div2\times10=1,600$ => -1,600 fpm is your desired rate of descent. How do I calculate without using tangents for degrees, other than 3: 2,5; 4; 5 ...? In my last question I got it wrong, even though through math the answer was correct.

• So every once in awhile I see an article talking about the air traffic control strikes in Europe like this one: European air traffic controllers to strike. How does this affect me if I am flying to Europe? Do they just close the doors and all airspace becomes uncontrolled airspace? I'm guessing not, but that's what I envision when I hear that! What happens if they go on strike while I'm over the ocean on my way there?

• I'm from Brazil, and here we use the West/East rule, so we use an odd flight level when we fly between 0/360 - 179, and when we fly between 180 - 359 we fly in an even flight level. But what should you do in other countries? Where I can find those rules? I've heard that in Europe it's totally different, and that in some countries in Asia they use meters, instead of feet. Where can I find this information?

• Many larger airports (class Bravos) have a landing fee. What's the process for assessing and collecting the fees? How do these landing fees work with general aviation aircraft? Where can I find out what the fee will be? Is it published? How will I be charged the fee? (Pay before leaving the airport, bill sent to my home, etc.) Is the landing fee a flat rate or is it calculated based on aircraft weight or some other factor? I've heard that the landing fee is generally waived if you buy a few gallons of (overpriced) gas at an FBO, is that true? Example scenario: I offer to take a friend up

• The alpha vane is an external probe used to measure the angle of attack. I have been trying to understand how exactly it works, but I can't find any clear explanation or simulation. Is the vane static or dynamic i.e. does it rotate along its central axis? Given that it has a significant surface area, I think that it would either: Rotate because of the force/drag exerted by the airflow, and give an angle of attack proportional or equal to its angle of rotation Measure the force being exerted on it via a force sensor embedded in the surface Is either of these correct? In short, how

• I have not even an idea about how I would search for that on Google, that is why I'm trying my chance here. As electrical engineer I have no clue about fluid mechanics. We all now that when water is pumped very fast into firefighters tube, it gets very rigid and tends to be straight. What is this effect called, I'm interested in doing some research about the forces applied by such a tube from its initial folded position to the final position. Thanks
