I managed to walk about 12km yesterday and throughout the walk was constantly looking up as aircraft landed on runway 27 @SanDiegoAirport. As @Airbus A350 destinations go this one is a little unusual approach wise… Follow on my walk as I explain…#WePilots #aviation #SanDiego 
Unlike other major #airports San Diego doesn’t have an Instrument Landing System (ILS) on R27,I’ll explain why later.The approach is also a little steeper than the norm to avoid small hills on the approach. It’s stunning day or night as you fly through the city to land. #WePilots
From Balboa Park most aircraft descend using a GPS approach that follows a descent angle of 3.5 degrees from a approach fix to the runway. An imaginary descent path to follow to the runway using GPS rather than an ILS beam from the ground. But why is SAN an unusual destination?
