Narrative:

On SID, turn was commenced to intercept R263. Upon reaching intercept angle, the FMS was changed to heading by PNF and not notifying PF. After going through radial, I asked PNF what was occurring. He didn't know (or remember) until discussed. After a correction was flown, london control issued us a heading and altitude.
