1North east side approach 24
Take Av. Pres. Vargas off BR-262 and make a left onto Av. Taquari. At the point were this road becomes Florianopolis you can enter a patch of sand. From there you have an excellent view of the approaching aircraft to runway 24.
2North west side ramp view
Continuing on BR-262 to the civil terminal will bring you past the threshold. From here you must be able to see the FAB ramp. However this is a busy dual carriage way and therefore hard to stop at. Go to the civil terminal itself. To the north east of it, near the access to the perimeter road, you should be able to see the civil and military ramps from the grass along the fence.
3West side ramp and runway view
After leaving the civil terminal make a left onto BR-262, and left again to Av. Wilson Paes de Barros. This leads along the perimeter fence and you will have a residential area to your right. When the undergrowth on the base allows, good views can be had of both the runway and FAB ramp.
4South west side approach 06
Continuing on Wilson Paes will bring you to the end of the residential area. The road is unpaved and leads into the barren lands. From this spot you can watch the landing aircraft at runway 06. You will have back light most of the day however. By following the sand paths counter clockwise through the farmland, you will reach the tree lined farm and thus spot 7, which see.
5South side approach 06
The airfield is hugged by many barrios and small patches of rough woodland, streams, and ditches on the east side. However, if you can find your way through the myriad of roads to the western side of this urban area, you can reach the 06 approach from the south east side as well.
Best bet will be to take Av. Tiradentes off BR-262, the first right on the large roundabout upon entering the city when coming from the airport; 20°27'59.79"S, 54°38'13.55"W). Follow this southward 2 km until you come to Melvim Jones, a street forking of to the right. Cross the water, the road is now named Petropolis. Make a left after the roundabout at the church into Paulo Hideo Katayama. After 1 km, you reach a T-junction, go right and you will arrive at the perimeter. You can spot the aircraft that approach runway 06.
6South side approach 06 (2)
There is another place from where the approach can be viewed. Alas, a stream blocks your path. But by following the road, R. Cel. Athos P. da Silveira, that runs westward along the perimeter you will cross it. Make a right towards the fence again. From here, a farm, or fazienda as they call it in Brazil, blocks your view a bit. You can see the threshold from behind and you will see the approaching aircraft albeit a bit high. It is unclear if, and how far, you can wander into the farm land here.
7South side approach 06 (3)
There is yet another spot in this maze. Go south west from the corner described at spot 6. Go right towards a tree-lined Fazienda. From here you can enter the farmland again. Alternatively, go past the farm and make a right into a sand path. This eventually leads to the other side of the approach and the path described at spot 4.
