Correction to last... only tandem seat fighters require WSO(FTR)
such as F-16D and F15. Both aircrew in the Apache are pilots.
WSO(FTR) are trained in navigation and operation of aircraft
systems. Simply put, they are to do what the pilot is not doing at
that point in time, to lighten the workload...
The interview is relatively simple. They will ask general
questions like why you sign up for this; why do you want to be a
pilot etc.
Word of advice.. Do not say you sign up so that you are able to
repay Singapore etc etc... They have been through countless
interviews and experiences. They will know what is wayang...
