Principles
• The combination of both a turn and
descent produces a highly tilted lift vector
• This means the vertical component of lift
will be very small
• Resulting in a high ROD and high turn rate
• Back pressure will be required to maintain
speed
Considerations
• Overbanking tendency

Considerations
• Underbanking tendency

Load Factor and Stall Speed
• Load factor and stall speed increases
therefore fly faster (80kts) to maintain a
safe buffer over the stall.

Considerations
• Limited bank angle (not in excess of 45°
Angle of Bank)
• Aim for a speed of 80 KIAS
• Rate of Descent 1000 Ft/min
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 80 KIAS and
apply firm back pressure.
Air Exercise
During
• ALAP
Exit
• BBB
Same as steep turn resuming glide attitude.
Airmanship
• Lookout
• Smooth but positive aircraft handling
• Correct Handover/Takeover procedure
• Aircraft within operating limitations
• Coordinated turns
• Awareness of spiral dive symptoms and
prompt recovery if necessary
Review
• Highly tilted Lift vector
• Overbanking / underbanking tendancy
• Load Factor

Pre Flight
Objective
• To understand the principles and
considerations involved in descending an
aircraft at a 45° ± 5º AoB, maintaining
balance and airspeed.
Application
• Control coordination exercise
• Height loss manoeuvre within a confined
space

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 70kts and
apply a little back pressure.
Air Exercise
During
• ALAP
• If done correctly, descend 500ft every
360
Exit
• Same as steep turn resuming glide
attitude.
Straight & Level
Aim: To learn the principles and considerations of
straight and level flight, and how to maintain it
Application:
•Used in the cruise segment
•Shortest distance between two points
•Improve passenger comfort
