So what are the ways to remove smoke from the cabin? Luckily they were only 20 minutes out from a Honolulu, but suppose they had been 1-2 hours away from the nearest suitable?
Suppose the crew corr correctly diognoses the problem as being smoke from one of the packs. The Airbus initial procedures from smoke and fumes calls for the switching off of Cabin Fans. Once the smoke source is detected and isolated would one be tempted to switch the fans back on to try and get the fumes out faster? I know that large portion of the cabin air is recirculated, but eventually it would be replenished. With the Cabin Fans off is there any way to get the smoke out?
