WRC-297 does not address the flexibilities of nozzles on heads. This type of configuration is outside the scope of this particular bulletin.

Implementing WRC-297 in this situation anyway (by specifying the orientation 90 deg from reality) means you are making assumptions, but it is the only way to get WRC-297 to work. If you do this, make sure you document everything so reviewers and owners know what you did.

Your alternatives are PD-5500 and/or Finite Element analysis.
