In this lesson you will practice the recovery procedures from spiral dives. You may also practice different types of slips, their entry procedures and recovery procedures.
Planned Activities
• Exercises 14, maybe 15
Reference Material
• VTA/VNC
• FTM
• Pilot Operating Handbook
Preparation
• Review exercises in FTM to understand different types of slips.
• Review the airspace around your airport using a VTA/VNC.
• Be able to answer the following questions:
1) What is the difference between a spin and a spiral dive?
2) What are some scenarios that can lead to a spiral dive?
3) Define Va.
4) What happens to the stall speed as bank is increased?
5) What is the proper recovery procedure for a spiral dive?
6) How do we recognize a spiral dive? What will you visually see outside and on the instruments and what will you feel?
• Write down your questions!
Tips/Rules of Thumb/Theory
• A spiral dive is associated with rapidly increasing airspeed and a rapid decrease in altitude
• When pulling out of a dive during a spin or spiral dive recover, level the wings first to prevent further tightening and aggravating the manoeuvre.
• The airplane will recover to wings level faster if using co-ordinated aileron and rudder
• A good rule of thumb is to wait until there is a slight nose up attitude and cruise speed or lower before adding power to recover and begin climbing. This helps prevent excessive engine RPM.
