STEEP DESCENDING TURNS Aim • To understand the principles involved in descending an aircraft at 45 AoB, maintaining balance and airspeed. Application • Height loss manoeuvre within a confined space • Control coordination exercise Overview • Revision • Principles • Considerations – Under-banking – Over-banking – Load Factor & Stall Speed • Air Exercise • Airmanship • Review Revision Forces in a Steep Turn g LF 2 cos60 1    W AoB LF cos  1 Revision Forces in a descent Principles • The vertical component of lift is reduced in both the descent and turn. • The combination of both manoeuvres produces a highly tilted lift vector. • Therefore, at the glide speed a high rate of turn and RoD will be achieved. • Back pressure will be required to maintain speed. Considerations A B • Overbanking Considerations • Under-banking Outer Wing Horizontal Distance Travelled Loss of Altitude Inner Wing L L Larger Angle of Attack Considerations Load Factor and Stall Speed • Load factor and stall speed increases therefore fly faster (70kts) to maintain a safe buffer over the stall. AoB LF cos  1 V V LF S NEW SOLD   Air Exercise Pre-Entry • Trim for glide attitude • Select a reference point • Lookout Entry • Roll into steep descending turns, as you would into a steep turn (B B B) except that, you lower the nose for 80kts and apply a little back pressure. • ≈ 1000 fpm During • ALAP • If done correctly, descend 500ft every 360 Exit • Same as steep turn resuming glide attitude Airmanship • Lookout • Smooth but positive aircraft handling • Correct Handover/Takeover procedure Review
