CASA also crashed on PAR approach.
There was certainly PAR equipment on Severnyi.
If it was in use and if it was PAR approach, we will know later.
All Polish military pilots are used to and current on PAR approaches.
Until recently most of the Polish military airfields didn't have ILS, just PAR.
In case of the CASA accident the pilots were used to ILS, flying to
Afganistan and mainly from EPKR, not to PAR.
Also the 154 pilots were mainly (or almost only) flying ILS.
Seldom, if ever PAR.
