Thank you for your response Hartmut and for the first sentence of your response William Bayne.? Maybe I need to get out more William, but I have never heard anyone argue against the the benefit of keeping a level attitude.? I do appreciate however that you both showed me the courtesy of actually reading my question and speaking directly to it.?
I suspected that there was no written reference or tolerance for this within the realm of approved data, but thought that perhaps there were citations in one of Mr. Weicks books or technical papers that could be pertinent. Cheers, Bill
