So what we‘ve just witnessed in the film
was a so called runway change A runway change is always an operational disruption.
It is always better to keep the direction steady as throughput is maximized that way. So why do we change? The main factor here
is the wind. As a rule, take-offs and landings have to be against the wind. It‘s like trying
to fly a kite – do it down the wind and you will utterly fail. Do it against the wind
and it will support you so you don‘t have to run and the dragon will climb very fast.
It‘s the same with aeroplanes. The original plan was to direct Condor 957,
coming from southwest, eastwards over the city of Munich, have it turn and fly to the
airport against the wind. In this case, we decided to turn the runway
while Condor 597 had already overflown Munich and been parallel to the runway. Thus, its
crew had to make a left turn to fly westwards, make a right turn and enter the approach to
the southern runways 08R direction. 08 is derived from the wind rose meaning an approach
to 080 degrees. In the beginning, the Instrument Landing System
was not yet available. The Instrument Landing Systems consists of two components, which
are two electronic antenna rays. One of them is located at the end of the runway giving
directional information, the other at the beginning of the runway giving altitude information,
so that if both are combined the aircraft is properly guided to the beginning of the
runway in both the right direction and altitude. But: the Instrument Landing System can only
be operational for one direction of the runway at a time, as they would mutually interfere
with each other. This is why the crew had to start with a so
called NDB approach. The NDB is an undirected radio beacon. It works somewhat like a radio
transmitter, sending radio waves into every direction. The pilot can fly towards this beacon, overfly
it and then depart using the opposed directional information. A rather complicated means of navigation compared
to an ILS approach. About 2 or 3 minutes prior to landing, we
were able to once again offer the Instrument Landing System. Captain: Alright I‘m entering the ILS information
for you. First Officer: Yea. Captain: Okay? First Officer: Okay. The crew accepted the offer because of the
higher precision of the ILS, so that within no time the crew was able to successfully
land on runway 08R. What I liked the most was the optimal interaction
of Captain and First Officer. He supported her perfectly in every situation of the approach.
I would have enjoyed staying in the cockpit on this flight.
