The Dreamliner departed runway 16L around 2AM local time,
and started its standard climb, making a left turn to the east. The plane
climbed to 1,850 feet, but then started losing altitude. We’re not just talking
about a few feet, but rather the plane started a steep descent, and lost 1,000
feet of altitude within 24 seconds, bringing it down to only 850 feet.
The pilots ended up recovering the aircraft, and continued
the flight to Copenhagen. The plane landed there without incident 6hr2min after
departing Doha. If you want to see all this data for yourself, just take a look
at the Flightradar24 tracking for this flight.

So, why would the plane lose 1,000 feet of altitude during such a critical phase of flight, when the weather conditions were perfectly good? The Aviation Herald reports that the first officer was the pilot flying, and while climbing through 1,600 feet, the pilots were cleared to fly toward the next waypoint (essentially an imaginary point in the sky used for navigation).
The first officer was flying the aircraft manually and
without flight director indications, and lost situational awareness, sending
the aircraft into a 3,000 foot per minute descent. The descent was so steep
that the sink rate exceeded the flap speed limits, as the plane was flying over
300 knots true airspeed at that point.
The captain then took control of the aircraft, and managed
to recover it at an altitude of 850 feet. Keep in mind at a descent rate of
3,000 feet per minute (and the rate usually increases quickly if you’re
sinking), that 787 was less than 20 seconds from having a very different
ending.

This incident is really concerning
For every catastrophe there are many near catastrophes, and
this was definitely one of those.
A Boeing 787 pilot shouldn’t be losing situational awareness
while manually flying a jet out of a hub airport in nice weather conditions.
Period. Yet somehow the plane got into a situation where it was within seconds
from ending up in the Gulf.
The most disturbing part of this incident is that it wasn’t
reported at the time, and it’s only coming out now, nearly a month later. I
mean, I guess I’m not surprised — I can’t imagine the pilot would have had a
job after an investigation was performed, especially in the Gulf region, where
you don’t have unions.
I feel really bad for pilots in the Gulf, as they work some
brutal shifts. No matter how much you program your body, performing such high
pressure and critical tasks at 2AM isn’t easy.
But the way that aviation becomes safer is by reporting
incidents, to be sure they can be avoided in the future. Therefore not
reporting something like this is reckless, even if it comes at the expense of
your job.
Bottom line
A few weeks back, a Qatar Airways Boeing 787 lost 1,000 feet
of altitude shortly after takeoff from Doha. The first officer was allegedly
manually flying the plane, and lost situational awareness, causing him to put
the plane into a steep dive. Given the sink rate, the plane was within seconds
of plunging into the Gulf. Fortunately the captain took control of the jet and
managed to recover it.
