Medical Treatments, Procedures and Investigations

Guidance for medical examiners when assessing a patient for either a general topic or condition - Medical Treatments, Procedures and Investigations.

Overview

There is a wide range of medical treatments and investigations that may affect the ability to fly safely. If there are side effects or complications following the treatment/investigation, then the recommended stand-down period should be extended.

The recommended no-flying/no-controlling time relates to treatment or investigation only. The medical matter or reason for the procedure must be considered separately – refer to your DAME or CASA.

These recommendations apply to all medical certificate class holders.

Recommended minimum stand-down times

The times stated below assume the certificate holder is feeling well afterwards and the treatment/procedure/investigation is uncomplicated.

If the certificate holder is unwell or there are medical complications, then you must refer to your DAME or CASA.
