Non-authoritative list of some labels:

• ARINC 429 Labels

But labels are not all standard, a specific LRU can define custom values. Labels used by a Laseref VI IRS to output values:

^{Source: Honeywell}

• Yaw rate = 330
• Wind direction (true) = 316
• Heading (true) = 314

(values are octal)

As commented by @Lnafziger, the value you are after may be derived from relative wind and heading, or is simply the heading as suggested by @DeltaLima. In any cases, there are additional parameters listed in the table. If you can describe further your needs, additional may be provided too.

You would have to confirm with the actual documentation of the specific LRU you are working with.

Non-authoritative list of some labels:

But labels are not all defined in ARINC standard, a specific LRU can define custom values. So you need to get label list from LRU documentation. For instance, labels used by Laseref VI IRS to output values to the bus are:

Your question is ambiguous about what you are looking for: Yaw is the rotation around an axis normal to the plan defined by longitudinal and pitch axes. The origin can be multiple:

It can be seen absolute, for instance referenced to the north, and it would be the heading. It can defined relatively to a given direction, e.g. the wind, and it would be computed from other values. More likely it can be a rate.

Here are some related labels:

• Yaw rate = 330
• Heading: True = 314, Mag = 320
• Track angle: True = 313, Mag = 317
• Wind direction: True = 316

(octal values)

Could you provide details about your needs?

Label are not all standard, each LRU can use custom values.

As commented by @Lnafziger, the value you are after maybe the direction of the last two values, or simply the heading as suggested by @DeltaLima. If you can describe further your needs, additional may be available too.
