PF/PNF
1. The BEA report of 2009 describes the pilot qualifications as follows:
]1.5.1.1 Captain (Let’s call him Pilot A) TT: 10,988 flying hours, of which 6,258 as Captain Hours on type: 1,747, all as Captain
1.5.1.2 Co-pilot (Let’s call him Pilot B) TT: 6,547 flying hours
Hours on type: 4,479 flying hours Note: It goes on to say: “ …This pilot’s licences allowed him to perform the duties of replacement pilot in place of the captain …”
1.5.1.3 Co-pilot (Let’s call him Pilot C) TT: 2,936 Hours on type: 807 Note: There is no mention of replacement pilot qualifications as per Pilot B above.
2. The BEA report of 27 May 2011 makes the following statements:
The Captain was PNF, one of the co-pilots was PF At 1 h 55, the Captain woke the second co-pilot and said "[…] he’s going to take my place"
3. I had always assumed that it was Pilot C who replaced the Captain as PNF in the LHS but given that Pilot B was the only one of the two co-pilots authorized to the replace the Captain, I now conclude that Pilot B (high time on type) was actually the PNF in the LHS while Pilot C (very low time on type) was the PF in the RHS at the time of the accident.
