The 109 patient lies behind the co-pilot to the rear bulkhead along the LH sliding door,thus also lenghtwise. The 5th fuel tank must be removed to lengthen the cabin to accommodate 5.8ft stretcher on a box type assembly. Guess it is ok if your averaged size patient is 5.6ft weighing 60-80kgs. We are now getting a 109 shortly so we will see first hand how it works as our average patients(other than incubator cases) weigh 80 to 140kgs with the length to go with it. We currently often have to lift the shortened dr seat at the patients head in the Squirrel so do not know how it will work in the 109. Will let you know
