John don't known the figures for second officers and number of scale if there is..
But for
-F/O, senior F/O have 5 scales..means you gone have an annual salary increase on your basic(3..4%) the First 5 years in your respective grade,after that no increase anymore
F/O basic salary goes from 21500QR(entry salary) to 24190QR (after 5 years)
SFO goes from 24200QR to 27240QR(after 5 years)
1 year= 1 scale. and related to your Basic salary.
-Captain haves 10 scales..means they gone have an annual salary increase for the first 10 years: goes from 31000QR(entry level) to 40460QR(after 10 years of being a captain,).
-Flying allowance: F/O:90QR/H SFO:105QR/H CPT:120QR/H
-Utility 300 QR/Month
-Transport 1500QR/month
Anytime you change of grade F/O->SFO->CPT you go back to scale 1 for the respective grade(entry level).
In other words if you become Captain after 4 years or 10 years , i won't make any difference in your initial Basic captain salary, you go back to Scale 1 captain salary.
Hope its a little bit more clear..
