Just below 20 000 Euros if you do 4 touch & go!
Hold the phone, you need 6 touch and go's including 2 full stops to gain the rating in EASA land. How much more for the rest?
And which airline in their right mind would take on A320 'blind rated' pilots over which the airline had no say or oversight in he training?? You can bet your bottom dollar you won't receive any low vis qualification what so ever, meaning an airline has to invest in you in any case, and let's guess, the bare minimum number of sims before first shot at LST. So 7? Training slots and the LST, oh yeah, the requirement to join the course must be a big cheque right? No assessment (well, meaningful one) to see if you are suitable? So you bin a sim or the LST, hey presto, you get charged for yet another remedial trg slot then pay for another LST (all of which you already paid for out of your cheque, but the company charges you again in any case). Quite different to any airline that holds a TRTO!
As corporate-pilot says, throwing money at a problem won't make it go away. This obsession with ' I must be in the 320/737 or it's all been a waste of time and I will never get to fly long haul'' mentality shows that perhaps some here really were blinkered by glossy brochures. The 320 flies you, why bother being a pilot at all?
now the caravan or dash or RJ100, and corporate types are good pilot makers!
