ing -p of about 6, but the airplane is very unstable in this position, which anyone will acknowledge who has snapped out of a long tail slide. The minimum gliding angle during a tail slide would be cot-1 6.0 or 9J°, and that during an inverted glide cot-1 2.7 or 20°. In this position the stability… … tea 200 W6 2-10 eso add soo 320 340 0 20 jo go so too 120 mo igo teo Anqle cf ottoc^ Fig. i::.—Forces and moments on complete JN HI model around 360°. CONCLUSION.
