As per the latest,.. (Since 10 months or so)
Any flight related activity e.g. SIM or Flight will result in a full pay. This is called on your pay slip as Flight allowance (=tax free) this comprises roughly 50% + of the basic salary. Because things can take up to 3-4 months this was being 'taken care' of by a random observer SIM session for which you would not even have to attend, but just to check-inn and go back home in idle months. As Bus Driver Man was referring to. You could request such a SIM session at the end of idle months so you would end up with a full salary. However, since 10 months or so this has changed! During ground training and roughly 1 to 2 additional months, if unlucky you might end up with 3500$ or so. There will be no more such SIM's available for salary purposes. Hope this answers the question.
