Seconds from touchdown, you see low-level warehouses, perimeter fencing and plane hangars. But just before the runway appears, you hear the engines roar to full throttle and find yourself soaring upwards in a powerful climb. You’ve just experienced a go-around.

There are lots of reasons for this manoeuvre. Also known as ‘missed approaches’, they happen when either the pilots or air traffic control (ATC) decide conditions are unsuitable for landing. The plane is then given full thrust to climb to a safe altitude before trying again.

Why does it happen? One reason is weather. If the pilots cannot see the runway at the altitude known as the ‘decision height’, they will go around until a rain squall or fog clears.

Another reason is congested air traffic. ‘When the distance between two landing aircraft goes below a certain distance, one aircraft is taken out of the landing sequence by ATC to maintain safe separation,’ explains Captain Peter Hudson. ‘Linked to that, if an aircraft takes too long to clear the runway, we will go around’.

‘A go-around is a standard procedure and we prepare for it as part of our recurring training in the simulator roughly every 90 days, so when it does happen, we know exactly what to do’, says Captain Hudson. ‘They’re one of the more common uncommon events that happen.’
