I have a couple of questions regarding de-icing of full scale commercial jets. I’m trying to prep for being an expert witness on an environmental matter related to de-icing.</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
Is the purpose of the de-icing fluid just to knock off the ice prior to take off or is it also intended to remain on the plane during flight?</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
Do commercial jets contain any other mechanism for preventing or stopping ice buildup during flight (e.g., heating elements)?</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
I always assumed that all de-icing activities occur out in the open. However, I’ve heard some airports now do this within enclosures. Are these enclosures two side (i.e., the plane pulls straight in one side of the enclosure and straight out the other side
of the enclosure without raising and lowering doors on the entrance and exit?</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
Any other details you can provide me would be appreciated.</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
Thanks</p><p style="margin: 0in 0in 0pt; font-family: "Calibri","sans-serif"; font-size: 11pt;">
