Mathilde i think the only Duty limitation we have is based FDP (flight duty PERIOD)...there is no limitation on Duty time/month or year, the only limitation i known(per month and/or year) is based on FLIGHT time not duty time.(on top of that Standby is free duty..).
(I Might be wrong.. as OM part A is not my best friend
)
The reason:
Is it because one pilot didn't pick up his/her phone during his/her standby period(cfr one of the last ACN)..that now we all have to be punished and given more standby and less days off...
Standard procedure in QR: ONE pilot F..k up, and we ALL have to pay for it!
