Every major airport has Noise Abatement Procedures (NAPs), which are procedures designed to reduce the impact of aircraft noise on the community. There are some limitations to the use of NAPs and they may not be used if they generate delay and congestion, as this can cause noise and emission impacts. Air traffic control or pilots may not be able to use them in certain situations, for example weather conditions or operational requirements. 

At Hobart, during tower hours (between 5:50am and 10:10pm) NAPs preference instrument approaches and departures for large aircraft (e.g. jets).

The VHF omnidirectional radio (VOR) is the least preferred instrument option and may only be used for flight training for small aircraft (under 5700 kilograms) or for operational reasons when no alternative approach exists.
