And yes, the height restrictions in the CBD of a modern city are pathetic!!
News & Discussion: Height Limits
Was a 200m observation tower approved on north terrace with a restaurant at the top. However was withdrawn due to lack of demand. Theres a thread on it it somewhere here...bm7500 wrote:I'm not familiar with that project..Will wrote:Not neccesarily.

First, I thought the height limit that was imposed were a joke.
After a couple of months of observation, I did realised how low some planes can fly through the CBD airspace. I know they don't fly through the centre of the CBD, which normally routes from North Adelaide, through to the railway station, through to West Terrace and down to Mile End, but anything could happen.
Even a slightest increase or changes in the wind direction could swerve and shift the whole dynamics of the plane. So it is very important to have some space just in case of an emergency.
However, those planes that fly really low through the CBD are the small private single-engined aviation plane, they fly at ridiculous height when landing.
Unless we move our airport to another location, which is unlikely, then we have to comply with the height limit.

Hi Edgar, commercial aircraft generally don't 'stray' from their course...
The main reasons that there are height restrictions on the city is so aircraft taking off from Adelaide airport have enough space to execute a 'missed approach' or emergency go around should they have an engine failue on take off. The airports also have what they call an Obstacle Limitation Surface (OLS) & Precision Approach Navigation Surfaces (PANS-OPS). These are invisible surfaces associated with aircraft approach & departure and are aligned to each runway strip at an airport. OLS and PANS-OPS identify the lower limits of the airport airspace which need to be maintained free from obstacles.
The actual maps showing heights etc can be found on pages 21 & 22 here: http://www.aal.com.au/pdfs/AAL_Master_Plan_04_App.pdf
