Just a thought after looking at the L1011,who can claim the largest glass area of a cockpit window on a commerical aircraft?
I'm pretty sure it's the side windows on the 787...that's a flight deck with much more total glass area than a 777 and that area is distributed on 4 windows instead of 6. There are other flight decks with big windows but they're all 6 pane sets, that I can think of.
This is one of those instances where this was probably not the exact right question to ask. When a flight deck is designed, window size is a fall-out of pilot vision requirements. There are flight decks with very large glass (measured in area), which provide less pilot visibility than flight decks with smaller windows, but which are designed with a better flight deck layout. A huge factor is how far the pilots eyes are located forward in the cockpit. Older airplanes tended to have the pilot seat mounted further aft from the windows, which made a significant impact on what could actually be seen outside, sometimes even in flight decks with very large windows. The graphic below is an illustration of how flight deck windows are evaluated for the vision they offer the pilot, measured in degrees. If you had this for multiple aircraft, you could make a very relevant comparison, determining which aircraft offered its flight crew the best visibility from the flight deck.
The right question to ask is probably "What aircraft offers the best flight deck visibility?"
