Navaid outtage & SID
I was flying out of Zhengzhou, China last month and was told by my company not to accept the usual SID due to the NDB for the SID being out of service.
It seems to me that a 737-800 with a few GPS's and a nice FMC could probably do just fine without an NBD, but I'm uncertain where the info is to prove or disprove this.
Any suggestions?

If it says ADF required..etc....you are definitely not authorized...also perhaps GPS/RNAV is not approved for navigation i.e the SID is not authorized...or quite simply your company forbids it in their OpsSpecs...All the 'Laws' for DPs or SIDS IAPs...are on the chart or in the OPSpecs

Well, I don't see anything on the ZHCC BS-11D SID chart that says NDB req'd.
I think this is the same logic that was cited when I asked if we could do the GPS-overlay approach for a VOR that was out of service and was told, "No. How can you do the approach without a VOR????"
Still looking for some reg. . .

GPS use is not universally approved for all types of Navigation... very similar to the fact that you can't use GPS in order to calibrate your VOR receiver even though it definitely would work...
you must either do a VOT test or cross check between dual receivers...if you did; this will be the applicable reg*. ---assuming you work for a US carrier---and even if it is approved on the chart .... your OpSpecs are regulatory--and are the company's medium for part 121 compliance!
I'm not being a wise *ss
*91.13 Careless or reckless operation
(a) Aircraft operations for the purpose of air navigation. No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another.
(b) Aircraft operations other than for the purpose of air navigation. No person may operate an aircraft, other than for the purpose of air navigation, on any part of the surface of an airport used by aircraft for air commerce (including areas used by those aircraft for receiving or discharging persons or cargo), in a careless or reckless manner so as to endanger the life or property of another.

Yes, yes, yes. POM/FOM is a reg. However, a Chief Pilot saying something over the phone or on a note on his desk is decidedly not.
Pan-Ops, FARS, whatever. I'm looking for something black and white and reg-based.

You're looking at it back to front.
The point is that if it is not an RNAV SID then you need to have all the beacons on the route serviceable, since they are your navigation reference. The same with the VOR approach example.
The fact that you are using your nice FMS to get the a/c along the track is irrelevant, you are supposed to have the raw data displayed to ensure that you actually are following the correct track.
The problem that still exists in large chunks of the world is that modern GPS/FMS systems are too accurate! They take you to where the beacon is supposed to be rather than where it actually is, and all the flight testing for obstacle clearance was done by someone tracking the real beacon.
So if you are not cross checking the raw data you may be in for a shock one day!

From the FAA instrument Procedures Handbook although the criteria for you may be PAN-OPS and not TERPS not familiar at all with JAR-OPS--so I cant comment:
PROCEDURAL NOTES
Another important consideration to make during your
flight planning is whether or not you are able to fly
your chosen departure procedure as charted. Notes giving
procedural requirements are listed on the graph
portion of a departure procedure, and they are mandatory
in nature. [Figure 2-25 on page 2-25] Mandatory
procedural notes may include:
• Aircraft equipment requirements (DME, ADF,
etc.).
• ATC equipment in operation (RADAR).
• Minimum climb requirements.
• Restrictions for specific types of aircraft (TURBOJET
ONLY).
• Limited use to certain destinations.
There are numerous procedural notes requiring specific
compliance on your part. Carefully review the
charts for the SID you have selected to ensure you can
use the procedures. If you are unable to comply with a
specific requirement, you must not file the procedure
as part of your flight plan, and furthermore, you must
not accept the procedure if ATC assigns it. Cautionary
statements may also be included on the procedure to
notify you of specific activity, but these are strictly advisory
and

AOPA Online: Air Traffic Services Brief -- Use of GPS in lieu of DME/ADF
Effective July 16, 1998, pilots may substitute IFR-certified GPS receivers for DME and ADF avionics for all operations except NDB approaches without a GPS overlay. GPS can be used in lieu of DME and ADF on all localizer-type approaches as well as VOR/DME approaches, including when charted NDB or DME transmitters are temporarily out of service. It also clarifies that IFR GPS satisfies the requirement for DME at and above Flight Level 240 specified in FAR 91.205(e). This approval represents a major step toward removing the need to retain DME or ADF in our cockpits for any reason.
Note: Air carrier operators should consult their operations specifications and their principal operations inspector for approval.
Limitations
There are still three instances in which DME or ADF are still required.

Note: Air carrier operators should consult their operations specifications and their principal operations inspector for approval.
Limitations
There are still three instances in which DME or ADF are still required.
- NDB approaches that do not have an associated GPS overlay approach must still be flown using an ADF.
- A non-GPS approach procedure must exist at the alternate airport when one is required to be filed by regulation. If the non-GPS approaches on which the pilot must rely require DME or ADF, the aircraft must be equipped with DME or ADF avionics as appropriate. GPS substitution for DME/ADF is not permitted in this case.
- DME transmitters associated with a localizer may not be retrievable from your GPS until the manufacturer incorporates them in the database. Pilots are not authorized to manually enter coordinates.
The problem that still exists in large chunks of the world is that modern GPS/FMS systems are too accurate! They take you to where the beacon is supposed to be rather than where it actually is, and all the flight testing for obstacle clearance was done by someone tracking the real beacon.
So if you are not cross checking the raw data you may be in for a shock one day!

Then what BizJetJock Said it the most conservative answer so probably the best---until you get clarification...sorry I definitely can't say anything about Korean Law

It really depends on your OPS Manual. For example we do not need any raw data coverage at all as long as we do have 2 FMC, 2 IRS and 2 GPS operating and ANP is below required RNP (0.15 for approaches, 0.30 for departures). Even if raw data is available it does not need to be cross checked if the above conditions exist. Granted, that is under EU-OPS instead of US or korean regulations.

I'm digging through the company website trying to dig up an English version of the ops specs.
I've seen airports that weren't where airports were supposed to be in China databases, so I know what a couple of the remarks are about. I've also flown RNP approaches in some scary valleys, so I understand the breadth and limitations of the dangers.
I've already been given a conservative answer by the CP. I needs me some facts.

From ICAO:
China advised APANPIRG/19 that
WGS 84 implementation is in
progress and planned to be
completed in 2010 for all existing
airports. All new airports will use
WGS84 immediately.
So that's a maybe. . .

Always follow what the CP says
if he or the DFO are friendly types then..you could ask for clarification or an explanation, or a referenc in the procedures...but if the 'OspSpecs' are not in English

Bear in mind that the default coding for a waypoint is fly-BY - conventional procedure fixes are, by definition, fly-OVER. The fifference could be critical under some circumstances.
That aside, my original question wasn't so much on construction of SIDs and TERPS. It's a question of where does it say what my CP says it says - that you can't do a pilot-nav SID with two FMCs, two IRSs, two GPSs, two autopilots, two pilots and a partridge and a pear tree?
We fly enroute with navaids out all the time. VOR U/S? No prob. Where does it say that that is acceptable?
I would think that if their WGS84 compliance is questionable...it could be dangerous the reason I think it's allowed in the US is because the data is internally consistent and predicated on a single reference datum.

Jepp ATC - Flight Procedures - General Principles (Extracted from ICAO Doc 8168)
Section 1.4 - Use of Flight Management System (FMS) / Area Navigation (RNAV) Equipment
1.4.1 Where FMS/RNAV equipment is available, it may be used to fly conventional procedures provided:
So as stated above, even thou the aircraft is perfectly capable of operating independently of the ground based aids, you are still required to tune, identify and display the "raw data" for SID's and overlay approach's VOR's etc.
Hope this helps in some way?
Section 1.4 - Use of Flight Management System (FMS) / Area Navigation (RNAV) Equipment
1.4.1 Where FMS/RNAV equipment is available, it may be used to fly conventional procedures provided:
- the procedure is monitored using the basic display normally assosiated with that procedure; and...
- the tolerances for flight using raw data (dispayed) on the basic display are complied with.
