The news in Europe has been dominated by Boris, the storm that hit Poland, Czech Republic, Romania and Austria over the last days. Rivers got out of their beds, trains and roads were impacted and air traffic too. I was flying to Vienna myself for a long weekend and my flight was delayed and also entered a holding pattern before landing and the flight home was delayed too.
How do high winds impact ATC? For one, only one of the two runways in Vienna was available, runway 29, as the other runway would have too much crosswind. Secondly, stronger winds and especially gusts lead to more go-arounds, requiring additional capacity and ATC reduces capacity to account for it.
Another aspect is how strong winds reduce capacity on final, as aircraft move slowly over ground. What can ATC do about this? One option is to implement time-based separations instead of distance-based separation and also optimize pairwise separation. EUROCONTROL encourages the LORD concept and some airports like Heathrow and Amsterdam have implemented it. It is not something that ATCOs can manage alone but with good system support, this allows them to squeeze a few more arrivals per hour. We had a podcast episode about this, with Sebastiaan de Stigter of LVNL, click here to listen to it.
High winds have no effect on our scanning of the air traffic management market and we keep monitoring it, day in, day out, and you’ll find the usual selection of what we captured below. Don’t forget, it is only a third of what we captured and if you want the full package, including calls for tenders, contact us and let us discuss!
