Here is a
place where we can capture some of the hard-won air safety experiences
of our colleagues. This forum sets out to shares some of the most
important lessons learnt by experienced pilots in the aircraft or in the
simulator...
The
following stories are presented as they came - without any grading of
importance or identification.

Landing
after a thunderstorm
In 1997 I
was landing an A310 in Manila following the passage of a
thunderstorm. The airport was open and visibility was good. It was
still raining but the main downpour had passed. Just as I was
touching down I was shocked to see that the runway was awash with with
standing water and serious bird bathing. We had real difficulty
stopping the aircraft within the confines of the runway, as we skipped
from one bird bath to the next.
Here's a
similar situation with worse consequences...
Loss
of control - Runway covered with standing water
1998 - A UPS flight
crew trying to land at Houston's Ellington Field during night-IFR
conditions. Tropical Storm Frances was whipping up wind and rain and
some of that excess water may have contributed to the Boeing 767-34AF
ending up on the grass next to the runway. The aircraft was
seriously damaged in the process. The "autoland"
approach and landing were uneventful, but the pilots say there was
standing water and minimal braking action on the ungrooved runway.
Lessons
for us all
Give the runway time to drain after heavy rain, especially if the
drainage is doubtful. Build up a knowledge as far as possible of those
runways that are grooved or porous surface.
Tip
On final after rain a glossy appearance of the runway surface is a give
away of the presence of standing water. A well drained
runway should be matt colour when wet... this will even show in the
landing lights at night below 200 feet.

Be
prepared for a Go-around
On a line
check flight we were making an approach in a strong tail wind. I
was high on slope and having a lot of difficulty getting the speed back
and getting back on slope. At about 700 ft. AGL I was
thinking I would have to go around, when the tailwind shear effect
finished and we sort of fell back into the slot - for a good short final
and landing.
Walking back
to the terminal with the check pilot, I casually remarked that I was
just about to go-around before the approach came right. To this,
the check pilot remarked: "I was just about to tap you on the
shoulder and tell you to go-round."... which would have been end of
check!
Lesson
learnt
If a check pilot tapped you on the shoulder and said go-around, how
could you ever convince him later that this was what you were about to
do - even if the timing between the two of you was a matter of
seconds? This prompted thought on how to keep your crew in the
loop, check flight or not.
Tip
If you see a situation arising where a go-around looks like a
possibility - say out loud: "be prepared for a go-around"
or something similar. This keeps your crew in the loop and mentally
rehearsed for the situation. You have positively made a plan for the
circumstances and taken uncertainty out of your crew's minds.
Hopefully you wont be caught in a situation like the following... |

Handling
abnormal Flight Situations
A very good CRM
point made on voicing thoughts and intentions to the rest of the crew
prior to a Go-around...
Further to that I was given this
tip recently during a LOFT ~ When an abnormal situation has occurred, it
is often helpful for the Captain to give a mini summary of the situation
together with his intentions - and also ask the crew for any other views
that they might have. Often the other crew might not speak up for fear
of making a fool of themselves, but they might have some helpful ideas
to bring to the situation.
Another similar point - when we do
system abnormals in the Sim, we all pay attention to the indications for
the training benefit. However on the line the Captain has to
designate who will be glued to flight instruments ATC and flight path
etc. In the aircraft it takes quite some discipline to ignore an
amber or red light - and fly the aircraft - which may be critical at low
level. |

Someone
always watching the shop
We were conducting asymmetric base
training in a B727 at Avalon airport, Victoria, Australia. Just
after V1 the instructor pulled a throttle and we started an engine out
rotate and climb. At just this moment the Tower called and alerted
us to a B747 in the circuit and passing over our climb out path at 1500
feet - ahead and passing left to right.
We all fell into the trap of
looking out for the B747, and in so doing a forward input was made on
the controls. As we were all looking upwards, no one was cognisant
of the flight path. Next moment the Tower called and asked "confirm
your operations are normal". As I looked downwards, I was
horrified to see that we had descended to tree level. The day was
saved and a safe climb out was recovered... thanks to the tower.
Lesson learnt
We know that someone should always be watching the shop - but it takes a
lot of discipline when something unusual happens. This is
compounded by negative sim training, where both pilots focus on the
problem for training purposes.
Tip
When an emergency or abnormal situation occurs, make sure someone is
exclusively "watching the shop".

Priorities
on the line
As a Line Training
Captain one of the most satisfying jobs is assisting a First Officer to
transition to Captain. Airline training programs vary between operators,
but in this airline they used the system of having the trainee normally
fly with the same Training Captain for 100 hours of line flying
development. This was a very satisfying and challenging training
experience and often life time friendships were made this way.
One example of a
very good training scenario was in the case of departure out of home
base on a track of 340 deg with an Air Traffic Control (ATC) instruction
to temporarily hold 3000 feet altitude on initial climb. In such a
situation I would ask the trainee – what is your most important
priority now?
Usually the
trainee would look around the cockpit for something forgotten – are
the flaps up?, is the after takeoff. check list complete?, Do we need
anti-icing (winter), etc. All good operational considerations – but
not the main thing at that time. Often I had trainees "give
up" at this stage for lack of ideas. Well, what about the fact that
we were on at 3000 ft level on a track for a mountain 14 miles ahead
reaching to 3400 feet?
Ok, a new ATC
clearance should fix the problem… but what if ATC became distracted,
say with an emergency somewhere else. Now the final responsibility
for the safety and disposition of the aircraft rests with the flight
crew, and the Captain in particular.
Lesson learnt
Put in its most basic terms, the two main priorities for a pilot are to
get from A to B without hitting the ground and without hitting another
aircraft - or put another way: Traffic and Terrain ~ situational
awareness.
Tip
We think we know something this basic, but often it is through some
non-fatal practical experience that the point is driven home to us
permanently. |
