Not so fast. Some of the later Pan Am -500's had digital AP's in them.
Negative.
Only the AP/FD glareshield panel appeared to be 'digital'...go down into the MESC and will be found many of the same units as on earlier aircraft.
You will note however, that these specific aircraft had localizer backcourse automated guideance, a PanAmerican requirement at the time.
Of course, most of the -500 model aircraft had active aileron gust relief augmentation, as well as other minor improvements.
MDLC?
Yes, that too.
I always had the Normal Checklist in one hand and the Emergency Checklist in the other. 411A your glasses must be a shade tinted, but at the time it was an awesome machine.
Shade tinted, no doubt.
However, in the last twenty nine years I've been flying the airplane, the 'emergency checklist' was not used once.
Abnormals, yes ( a few times),
emergency...no.
