What does sub part Q say about dual basings, 50km, 60mins?.
Not too sure about that one but regarding theboxer's post when he says:
A colleague of mine got up at 3:15AM today for his drive to PMO, got back home at 6PM and will be up at 3:15AM to work tomorrow.
and
Everyone is exhausted after only 1 day, I need to sleep in the cruise.
it might be useful to have a read at the Operator's responsibilities in subpart Q:
3. Operators' responsibilities
3.1. An operator shall nominate a home base for each crew member.
3.2. Operators shall be expected to appreciate the relationship between the frequencies and pattern of flight duty periods and rest periods and give due consideration to the cumulative effects of undertaking long duty hours interspersed with minimum rest.
3.3. Operators shall allocate duty patterns which avoid such undesirable practices as alternating day/night duties or the positioning of crew members so that a serious disruption of established sleep/work pattern occurs.
3.4. Operators shall plan local days free of duty and notify crew members in advance.
3.5. Operators shall ensure that rest periods provide sufficient time to enable crew to overcome the effects of the previous duties and to be well rested by the start of the following flight duty period.
3.6. Operators shall ensure flight duty periods are planned to enable crew members to remain sufficiently free from fatigue so they can operate to a satisfactory level of safety under all circumstances.
