In an aircraft having a pressure window mounted in the hull, an interior window assembly is removably mounted in an interior wall spaced from the hull. The interior window assembly is in register with the pressure window to enable occupants of the aircraft to view the outside. The interior wall has an opening formed therein to accept the interior window assembly and the portions of the wall surrounding the opening are biased toward the interior of the aircraft. The interior window assembly includes a windowpane mounted in a frame. The frame includes a flange that overlies the inboard surface of the portions of the wall surrounding the opening, and the bias of the wall portions is exerted on the flange. A constraint means is affixed to the hull of the aircraft and releasably engages the frame to constrain the frame from inboard movement. The bias force of the wall portions and the constraint means cooperate to hold the window in place. Preferably, the interior wall is comprised of stiffly flexible panel members that are flexed upon placement of the window assembly into the opening and tend to return to their unflexed state, thereby exerting the bias force on the flange.

In an aircraft having a pressure window mounted in the hull, an interior window assembly comprising: an interior wall panel mounted within the aircraft and spaced from said hull, said interior wall panel havng a window opening formed therein in register with said pressure window, the portions of said wall panel surrounding said window opening being of stiffly flexible sheet members that are flexed upon insertion of said window assembly into said window opening, the internal tendency of said wall panels to return to their unflexed state providing a bias force on said wall panel portions in an inboard direction; a rigid windowpane mounted in a frame, said frame being of substantially the same size as said window opening; a first flange extending from an inboard end of said frame, said first flange being of a dimension larger than the window opening, such that portions of said wall surrounding said window opening abut said first flange; and, frame constraint means affixed to said hull adjacent said pressure window and removably engaging said window frame to resist movement of said frame in an inboard direction. 3. The window assembly of claim 2 wherein at least one notch is formed in the wall portion adjacent said window opening and further including at least one keeper block affixed to said first flange substantially coextensive in a fore/aft direction with said notch and engaged with said notch to constrain movement of said window assembly in the fore/aft direction. 4. The window assembly of claim 2 wherein a first notch is formed in the wall portion adjacent an upper edge of the window opening and a second notch is formed in the wall portion adjacent a lower edge of the window opening, said window assembly including first and second keeper blocks affixed to said first flange, said keeper blocks being substantially coextensive in the fore/aft direction with said first and second notches and engaged with said notches to limit fore/aft movement of said window assembly, said keeper blocks abutting the respective upper and lower edges of said wall portions adjacent said window opening to limit vertical movement of said window assembly. 5. In an aircraft having a pressure window mounted in the hull, an interior window assembly comprising an interior wall panel mounted within the aircraft, and spaced from said hull, said interior wall panel having a window opening formed therein in register with said pressure window, the portions of said wall panel surrounding said window opening being biased in an inboard direction; a rigid windowpane mounted in a frame, said frame being of substantially the same size as said window opening; a first flange extending from an inboard end of said frame, said first flange being of a dimension larger than the window opening such that portions of said wall surrounding said window opening abut said first flange; a second flange extending outwardly from said frame positioned within the space between said interior wall and said hull; and frame constraint means affixed to said hull adjacent said pressure window and removably engaging said window frame, said frame constraint means including a spring arm having a first end affixed to said hull and a second end of substantially hook shape that releasably engages said second flange to restrain said window frame from inboard movement. 6. The window assembly of claim 5 further including a release opening in said frame adjacent said second flange to permit access to said spring arm from the interior of said aircraft. 7. The window assembly of claim 6 further including a clip member releasably affixed to said second flange in the area of engagement of said spring arm with said second flange, said clip member having a trip hole formed therein in register with said release hole. 8. The window assembly of claim 7 wherein said constraint means further includes a second spring arm having a first end affixed to said hull and a second end releasably engageable with said second flange at a position opposite the area of engagement of said first spring arm with said second flange, a second metal clip member removably attached to said second flange in the area of engagement of said second spring arm with said second flange, a second release hole formed in said frame constructed and arranged to permit access to said spring arm from the interior of said aircraft, and a second trip hole formed in said second spring clip member in register with said second release hole. 9. The window assembly of claim 8 further including a shade mounted on said frame inboard of said windowpane and operable between a position in which it covers said windowpane and a position in which it is contained within said frame, said frame including a guide channel in which said window shade travels, said first and second release holes being formed in said guide channel. 10. In an aircraft having a pressure window mounted in the hull, an interior window assembly comprising: an interior wall panel mounted within the aircraft, and spaced from said hull, said interior wall panel having a window opening formed therein in register with said pressure window, the portions of said wall panel surrounding said window opening being biased in an inboard direction; a rigid windowpane mounted in a frame, said frame being of substantially the same size as said window opening; a first flange extending from an inboard end of said frame, said first flange being of a dimension larger than the window opening such that portions of said wall surrounding said window opening abut said first flange; a second flange extending outwardly from said frame positioned within the space between said interior wall and said hull; frame constraint means affixed to said hull adjacent said pressure window and removably engaging said window frame to resist movement of said frame in an inboard direction, said frame constraint means including first and second spring arms, each of said spring arms having a first end affixed to said hull and a second end of substantially hook shape that releasably engages said second flange to restrain said frame from inboard movement, said first and second spring arms being spaced from one another and engaging said second flange on opposite sides of said frame, said frame including release openings adjacent said second flange to permit access to each of said spring arms from the interior of said aircraft; first and second clip members, each of which is releasably affixed to said second flange in the area of engagement of the respective spring arms with said second flange, each said clip member having a trip hole formed therein in register with its associated release hole; and a shade mounted on said frame inboard of said windowpane and operable between a position in which it covers said windowpane and a position in which it is contained within said frame, said frame including a guide channel in which said window shade travels, said first and second release holes being formed in said guide channel. 11.
