- • Activities, conditions and factors that may adversely affect an Aircrew member’s short-term medical or dental fitness to fly, or an Aircraft Controller’s fitness to control aircraft;
- • Duration of the TMUFF period;
- • Circumstances where AVMO or Dental Officers are to be consulted before flight to determine the duration of the TMU period; and
- • When necessary, TMUFF as related to infrequent flyers.
