To reach the embankment, on exiting T5
, turn right follow the foot path, walk past the bus stop (under cover of multistory car park) which will be on your left, as will be an undercover bike rack just past bus stop. Ahead on the left will be a Sofotel Hotel. As you walk along the footpath, you will see the T5
apron on your right, with A319, A320's parked at the gates. Overhead you will see the T5
Pod Cars heading out to long term carpark. Just keep the apron perimetre fence on your right as you continue to walk.
In about 3 minutes you will see a taxi rank and in the distance aircraft landing on runway 09L. Just walk down the hill where the taxies are lined up and you will see the embankment/mound in distance, covered with trees, which you can walk up and shoot from, as I have done on numerous occassions, without any hassle from authorities whatsoever.
Weekends are more likely to be busy with photogrpahers if weather is good. Light is generally better for arrival shots in the morning and just past lunch time.
Also if you have Google Earth, you can look at what I have described using a birds eye view, to get the lay of the land. If not just download, it takes seconds to set up.
