Are you attempting to say "OpSpecs," when you say "SOP's?"

OpSpecs are regulatory in nature in that they provide specific permissions and restrictions under the operating certificate to which they are issued. There is no OpSpec of which I am aware which limits a blue tooth feature in an aviation headset. Are you aware of such an Operations Specification?

If you're referring to company practices, policies, and procedures spelled out in an employee handbook or general operations manual, then no, those are not regulatory in nature. An employee is expected to adhere to the general operations manual procedures and may be held accountable for failure to abide those procedures as spelled out by the certificate holder, but for different reasons. I am aware of no company general operations manual or employee manual that prohibits blue tooth in a headset.

Are you?
