window assembly can take a variety of shapes such as a circular shaped or the trapezoidal shaped window frame assembly 400 illustrated in fig4 in another embodiment of the present invention illustrated by the assembly method shown in fig5 the window pane can be installed into the frame in a fashion that ensures that the window will not break or fall out of the aircraft when subjected to drastic changes in environmental conditions in step 510 the ir window pane 210 is set into the window frame 220 in step 520 adhesive 230 is applied at the area between the window pane 210 and the window frame 220 as shown in fig2 and 3 in step 530 the window frame 220 the window pane 210 and the adhesive 230 are heated to an assembly temperature which is at least an upper limit of a predetermined temperature range of interest e g the highest possible temperature that the aircraft is expected to encounter for example the upper limit temperature that most military aircraft will encounter falls within a range of between 130 degrees f to approximately 260 degrees f however those skilled in the art will appreciate that the upper temperature specified for a particular aircraft is based upon the characteristics of the aircraft and its expected use heating the window assembly to the assembly temperature with the adhesive in place allows the adhesive to cure to the window pane 210 and window frame 220 at a point in time at which the materials that make up the frame and the pane have expanded due to the high temperature normally the window pane 210 being a non metal expands at a slower rate and to a lesser degree than the window frame 220 which is.
