"An employer must ensure that crew do not work more than 2,000 hours in any 12 month period, of which total flying time must not exceed 900 hours.
Periods spent working overtime and on standby duty are captured under the definition of "working time" and should therefore be taken into account when calculating an individual's total annual working time. It should be noted that there was not previously any requirement in law or in CAA guidance which guaranteed a maximum of 2,000 hours annual working time."
This qutoe was taken from the DTI website on Civil Aviation (Working Time) Regulations 2004. Assuming that rostering periods are 28 days, there are approximately 13 periods in a year, one of which is holiday. Therefore, you are available to fly for 12 of the 13 rostering periods. 900/12=75 hours flying duty periods per 28 days. However, this is only an average. You can do more in one period. However, over the year maximum is 900 hours.
Hope that clears up the confusion.
PS. These regulations apply to Flight
and Cabin Crew
