The IAA have recently issued an exemption for 8.33kHz to certain GA operators. Full details are available in this article http://flyinginireland.com/2017/01/iaa- ... operators/ , however ultimately this will require the installation of an 8.33kHz radio in the future. Specifically;
- If you’re fitting an aircraft radio for the first time, it must be 8.33 kHz spacing compliant.
- If you’re upgrading your aircraft radio (replacing one box with another box), it must be 8.33 kHz spacing compliant.
- If you’re applying for an aircraft’s initial Cert. of Airworthiness or Flight Permit, any radio installed must be 8.33 kHz spacing compliant.
