Both PF and PM were training Captains.
WRT vision:
”The PF held a current Class 1 medical certificate, and as a condition of that certificate was required to wear distance vision correction and have available reading correction. These vision requirements were determined to have not influenced the occurrence. ”
Having reading correction available while being required to wear distance vision correction is nonsense. What does a pilot do with those restrictions on a medical? Switch glasses every time you look inside the cockpit?
