CX will reap what it sows.
On all fleets the CN upgrades are predominately experienced FOs who joined circa 2006-2008 (commands pending). The success rate is and will continue to be high for the next 18mth+. However, many of the JFO upgrades are at present from ex cadets with little or no experience prior to CX, many are struggling. (babysitting the AP anyone?). With training resources dwindling by the month management continue to squander resources, the 150 sector upgrade is on the cards.
Whilst every new joiner doesn't have to be ex Thunderbirds pilots, they should know the basics of stick and rudder, sadly this now seems to be missing.
