According to the leading newspaper Aftenposten, a B737 owned by Ryanair made a successful zero flap landing at TRF (Torp, Sandefjord, Norway) today. The runway at TRF is approx. 8000 ft, surface was dry and winds calm.
How serious is a zero flap landing under these conditions?

Hey, I live in Sandefjord, sorry I missed it then.
I guess it can't be too serious in terms of runway length with that small an airplane, because it's quite a long runway. I read on flightsim.no that once a 737-800 locked it's flaps at 15 degrees, caused a go-around and a hard landing, but nothing too seirous.

Quoting Raggi (Reply 2): Anyone have a rough figure for the Vref speed for a zero flap landing, in this case for a 738, or any other commercial a/c for that matter?
I only have data for the -700, but here you go:
737-700 Vref speeds (commonly) range from 125-135 knots. The procedure to land with flaps 1 or less with LEDs not fully extended (ie: totally clean wing) is to set Vref40 + 55 knots. That means your final Vref speed would likely be in the neighborhood of 180-190 knots.
I've flown no-flap landings in the sim, and it seemed very fast, but not as insane as the numbers might suggest.

It's no big deal just use a lot of nose up trim to keep the airspeed from increasing and use a lot of power adjustments. At least that's how you do it with a 172 don't know what it's like in a 737. No flap landing becomes a problem with short runways because the airplane usually wants to float forever.

Did a no TE flap landing in RNO several years back - it seems like the Ref speed was @175kts. This was in a -300 and we did have the LE devices, so that definitely helped. Landing was fairly straight forward (albeit fast), with a fairly nose high attitude. I never did learn why we couldn't get the flaps down. The alt flap system only got us the LE devices and nothing more - we had normal hyd pressure and everything else appeared normal. When we got to the gate, they worked perfectly. Weird.
