Determining a state of acclimatisation
Determining whether a pilot is acclimatised
The table below outlines the specific areas within CAO 48.1 Instrument 2013 that talk about how to determine the different states of acclimatisation.
At the start of a flight-duty period or an off-duty period, a pilot is considered to be acclimatised to a location if:
At the start of a flight-duty period or an off-duty period, a pilot is considered to be in an unknown state of acclimatisation if:
A pilot is considered to remain in their state of acclimatisation, whether acclimatised or in an unknown state of acclimatisation, until they have had:
Period required for a pilot to become acclimatised to new location (adaptation period)
Use these steps to determine the required acclimatisation period from Table 2 below:
- Determine the time-zone difference between the location where the pilot was last acclimatised (the original location), and each location where a flight duty period or off-duty period started since last acclimatised (later locations).
- Determine the greatest time-zone difference between the original location and the later locations (refer to the left-hand column in table 2 below).
- Once you have identified the time-zone difference, move to the right in the table to identify the number of hours the pilot requires to acclimatise, depending on whether they have travelled to the west or the east.
