Tu-154,
add on top of that the organization, quality of maintenance, status of equipment... (or lack thereof).
Nevertheless most Spanish FTOs must be crowded with customers because I have e-mailed and phoned 3 of them (including Panamedia) to enquiry about FI rating renewal and no way I could get hold of anyone.
On the other hand, are we talking 50k/year for a VFR instructor, or are we talking about CRI/IRI?
