Narrative:

In-flight at cruise the R1 window had a possible short circuit with accompanying smoke, fume, and 'pop' most similar to a small fire cracker. Captain (PF) and first officer (PNF) ran the smoke/fire abnormal checklist. We declared an emergency and descent landing to bna visual runway 13. Smoke/fire vented through the airconditioning system and did not continue. Communication with oxygen masks on was a problem. Must communicate with both pilots, cabin crew, and ATC. Each group requires a change of interphone panel/procedure. I think this is weakest area. Just is not any easy way to set up, but must just slow down and prioritize.

Title: EMER DECLARED. ACR CREW HAS SMOKE IN THE COCKPIT AND DIVERTS AND LANDS.

Narrative: INFLT AT CRUISE THE R1 WINDOW HAD A POSSIBLE SHORT CIRCUIT WITH ACCOMPANYING SMOKE, FUME, AND 'POP' MOST SIMILAR TO A SMALL FIRE CRACKER. CAPT (PF) AND FO (PNF) RAN THE SMOKE/FIRE ABNORMAL CHKLIST. WE DECLARED AN EMER AND DSCNT LNDG TO BNA VISUAL RWY 13. SMOKE/FIRE VENTED THROUGH THE AIRCONDITIONING SYS AND DID NOT CONTINUE. COM WITH OXYGEN MASKS ON WAS A PROB. MUST COMMUNICATE WITH BOTH PLTS, CABIN CREW, AND ATC. EACH GROUP REQUIRES A CHANGE OF INTERPHONE PANEL/PROC. I THINK THIS IS WEAKEST AREA. JUST IS NOT ANY EASY WAY TO SET UP, BUT MUST JUST SLOW DOWN AND PRIORITIZE.
