Flows are what we do prior to each checklist. Checklists in the 121 world are not read and do like Cessnas and Pipers. They are challenge/response. Meaning that your switches, etc. are already set up prior to beginning the checklist. The checklist mearly confirms switch position, that the task was done or the item is set properly. Flows are normally done just prior to reading the checklist, with a couple of exceptions.
The Receiving Flow (big set-up checklist) is done upon entering the cockpit. It is the most involved one since you're basically bringing a mostly shut-down airplane back to life (there is another one for power-up, but that's just to safely apply power). This is where the majority of stuff is set up for flight and most of the systems are checked. In the beginning, it'll take you about 15 minutes to do a receiving flow. Once you have the hang of it, you can do in about 5 to 7, depending on how long it takes for everything to align and if its First Flight of the Day.
99% of our Captains brief "run the flows when you're ready." That means when you feel it's about time for the checklist, get the flow out of the way. A good example is the Before Take-Off flow. If there's only a couple of airplanes waiting to go, I'll run my flow on the way to the runway (flight controls, xponder/tcas, notify fa, etc). If it's busy, I'll wait until I'm about number 5. This varies from day to day. If it's busy and we still have an engine shut-down, the taxi check needs to be completed prior to doing the before take-off flow. You'll soon get the feel for things and know when stuff should be done.
That's flows in a nutshell.
By the way, Congrats and welcome aboard!! Don't get down on the 69 airplanes. Something's in the works. Definately don't sweat it during training. You picked a great airline. You'll like it here. |
