Requirement to ident the navaid?

[rcbullock]

Where does it say you are required to ident navaids? I do just as good practice but I'm looking for it in print, either AIM or FAR.

Oh, excuse me, 14 CFR blahdee blahdee. (FAR means Federal Acquisition Regulations I think or very similar.)

you fed-guy!

FYI, 14 CFR means Chapter 14 Code of Federal Regulations. I have not heard of a reg anywhere requiring you to ID a navaid. But I have seen people bust checkride because they don't. ADF really need to be done. VHF if within the Operational Service Volume don't seem that important. BUT, when operating outside North America, I personally insist on it very strongly. Some countries don't follow any ICAO rules regarding navaids.

Jim, The question is what reg. There is no reg. The PTS is not regulatory. While it does give the minimum standards which SHOULD have as basis within the regs. In and of itself does not have any regulatory weight. It is good operating practice, especially when using NDB's and operating outside of North America. But when operating on the line and the Feds give you a route check, you will not hear them cite you for not doing so. So there is no regulatory basis. What do the crews with FMS's do? The radios tune themselves. And how about GPS?

 

[The FNG]

The Collins FMS 4200 auto-tunes 4 DMEs by default and can additionally auto-tune 2 paired VOR DMEs for a total of 6 DMEs and 2 VORs, plus GPS/IRS. The frequencies are auto-tuned based on aircraft position and a database of navaid service volumes. The FMS verifies actual station idents against database information and displays the identifier only if the signal is valid. Therefore, a tuned station is identified if the FMS displays the identifier in addition to the frequency. In this case there is no need to listen to the morse code.

Even if it is not a cut and dried Reg, I see it as one of those items that is easy to do and can save you a big headache.
This was driven home for me when I didn't bother to ident one day during my instrument trraining and found that it's difficult to fly the VOR approach for Pueblo when you're tuned to the Black Forest VOR up in the Springs.
But at least the instructor got some entertainment for a few minutes.

Identifying the navaid can also be used to have fun with non-pilot passengers. I once told my girlfriend that the morse code (during an NDB approach) was used to comminicate by pilots flying planes too old to have radios. She bought it until she realized that she was listening to the same sequence over and over.

I was in the doghouse for quite some time, if I remember correctly.

Wht argue about something so basic and important? It is like a computer -garbage in-garbage out! Make sure you are flying to what you think you are flying to.
I had a P.O.I on my 135 and the first thing he said on our checkride was if you forget to i.d a navaid we are going home early.
Whether it is a ndb or GPS- be sure of what you are flying to. I think it would have been a happier story in Cali if the AA crew had checked the spelling/ or lat-long before hitting enter.

 

[JetPilot500]

As was stated earlier, there is no reg requiring you to ID frequencies.


So, don't do it if you don't want. However, see what happens to you when you fly to the wrong VOR or intercept the ILS parallel to the one you were assigned to intercept. I think you'd be breaking a regulation there, or worse yet, you could get killed.

Even though my FMS is good enroute and I don't need to ident the stations, I always listen for the Ident on an ILS.

While I can't quote chapter and verse about the requirement to ID navaids, it seems silly that people are asking. How can you safely navigate if you aren't certain you have the correct navaid, or that it is turned on?

Regarding the usage of FMS and how they don't ID each freq used by the FMS logic:

-Most modern FMS systems have a method of notifying the pilot if the checking filters detect the system is degrading.

-Most airlines that I'm familiar with require a cross-check between "raw data" and FMS derived data to verify the FMS accuracy prior to depending upon the FMS solely for navigation.
