While it may not be likely, a friend of mine did a zero flap landing on his first flight as a captain on this plane. I always say... never say never.
What would cause a Zero Flap Landing?
If both flaps and slats wingtip brakes activate, a zero flap/slat approach and landing is required. The message is: F/CTL FLAPS LOCKED and F/CTL SLATS LOCKED. These two separate problems leave you with a clean wing.
Photo depicts only locked flaps.
Another reason could be a bit more serious. If the the SFCC 1 and SFCC 2 fail, we'll see:
F/CTL FLAP SYS 1 (2) FAULT
F/CTL SLAT SYS 1 (2) FAULT
This, too, is a dual malfunction. But you won't find a procedure in your quick reference manual. Why? The probability of "never" is taken into account. But it's important to note that in this situation the flight controls will degrade to Alternate Law.
How do you know when you're in Alternate Law?
Among other reasons...look for the X's on the PFD.
The interesting thing about these flap and slat failures is that while we don’t have flaps or slats, we still must "position" the flap handle as if we did. The flap handle is used to compute the speeds on the speed tape. Where as the position of the flaps themselves are used to depict the speeds on the ECAM. Thus, ECAM speeds are correct per position of the flaps (up)—But the speed tape is not.
Why do we want to move the flap handle to "1" if we have a flap malfunction?
Go-Around on the Bus
In the Boeing aircraft we had a button to push to execute the go-around. In the Airbus we use thrust lever position to TOGA. But how does the plane know? What if we needed TOGA thrust but we aren't performing a go-around?
In the event of a Go-Around, the Airbus won’t transition to the Go-Around phase unless the flap lever is in, at least, position 1.
Airbus logic is such that if we’re applying TOGA power during an approach (flaps out)—we're telling the airplane to go-around. There is no button pushing. If flaps are up, you only get TOGA thrust and the plane stays locked on the localizer and glideslope.
Systems knowledge is essential, especially in the modern planes… despite the shift in focus. A future threat to aviation includes advanced technology and what happens when it breaks. Will the pilots know what to do if they are faced with flying their plane when they lose their automation, without the systems knowledge to back it up? What are your thoughts?
The responsibility lies within.
Enjoy the Journey!
