High performance take off
1.150m for an A320, not bad.....
Arabia A320 at Sharjah on Sep 18th 2018 |
Especially when any tailwind component is taken into account..... :ugh:
|
Yikes. Not the first time that it has been done... DC10F at PANC... but at least Air Arabia has been clean living and survived the whoops. Wonder at what point the crew picked up the hints that they were going in the wrong direction. The Airlines response may seem excessive, but it gets rid of the easy but gross error that occurred here.

Ironically, the light aircraft with which it collided had taxied all the way to the end of the latter 10,000' runway rather than electing to depart from an intersection. |
This flight (L9-111) departs about 1630 local – daytime – surely at least one of the pilots must have looked out of the window at lineup and said, or thought, "that looks a bit short"? Or is everything "heads-down" these days?
Although of course I've no evidence, I do wonder if there was bit of non-CRM taking place, rather like Tenerife but without the disaster. Junior co-pilot: "Aren't we headng the wrong way?" Captain with press-on-itis: "No, no, let's get out of here." |
I am still trying to work out how this could possibly happen. This is a single runway airport in (I assume) good visibility. We are not talking Chicago O'Hare or Detroit Metro in the fog at night! Not only that but this airline is actually based there. Absolutely remarkable.

I wonder what the Aerodrome Controller was looking at?
|
While there aren't enough data points on the FR24 plot to determine exactly where the A320 became airborne, the last point shown with WoW is around 300 meters short of the upwind piano keys with a groundspeed of 67 kts (subject to usual FR24 caveats).

Hard to believe for those who know HRE, but it happened. |
On Sep 19th 2018 Air Arabia instructed their pilots that all intersection departures were banned with immediate effect... |
But having made that error, how can they have got it into the air? Presumably the take off run was calculated for 3 times the distance that was actually available. I am sure I have read on here that you chaps don't thrash the thing unnecessarily but derate appropriately. So they realized early on, did some rapid mental arithmetic and decided to floor it ?!
|
No problem.(sarcasm alert)
One time we only used about 3000' to lift off in a 777-200 full of pax with 10 hours of fuel. :} |
Well if Viet airlines can do a max takeoff. .. :D

Interesting I have seen a DVD related to their operations just a few weeks ago. It seems they always do intersections take offs and most of the times they tanker fuel from Sharja. Maybe this day they were lucky enough not to tanker or with a low load factor. From FR24 I saw the coming back flight left on time, I think with the same crew. As for sure immediately after take off this mistake was clear to the crew, to the control and to the management, wouldn’t have been better send a standby crew to do the flight back? I think their mood was terrible. |

Very good example of a knee jerk reaction.
Obviously, the long-recommended, verbal confirmation/callout by the crew that a runway one is cleared to line-up on/cleared to T/O from coincides with the compass heading of the aircraft before applying power to help prevent taking off from the wrong runway either wasn't incorporated into this Company's procedures or adhered-to by the crew if it was. The simple procedure of having both pilots verbally confirm Rwy clearance vs compass heading before closing a line-up checklist is a final backstop, prevention measure against this sort of thing when SA has broken down. This recommendation was already written in passenger and crew blood, and it doesn't really matter if one calls it "knee-jerk" or not. Sterile cockpit, approaching assigned altitude callouts, no circling approaches unless in VFR conditions, no side-stepping below 1,000' AGL, etc etc etc could all be said to have have roots in "knee jerk" reactions to incidents/accidents. It doesn't automatically mean they're the wrong answer. |

Had they lost an engine then it would have gotten rather messy. It's possible that the approach of the end of the runway encouraged forward movement of the throttles to make sure. |
Taking off from the wrong runway at home base am i missing something

He took off from the intended runway. But after turning on to it in the wrong direction. |
If this had been a BA 747 taking a wrong turn at Joburg all the " there for the grace of God go I " types would be swarming all over this.
