4.17 Slow Flight Airplane Characteristics
4.17.1 Introduction
This chapter provides the recommended procedures for the safe operation
of the Sportstar at airspeeds less than cruise. It describes flight at minimum
controllable airspeed; and information on stall and spin recognition,
characteristics, and recovery.
Slow flight is defined as any speed in the range from just above the stall to
just below the best endurance speed. This range is typically 3-5 KIAS
above the stall speed. You should be capable of flying the aircraft in this
speed range because you pass through it on every take off and every
landing. Practising it at altitude will give you the confidence to positively
and accurately fly the aircraft in this range when close to the ground.
4.17.2 Minimum Safe Speed
It may become necessary to fly at the minimum safe speed in order to get
to a landing spot with an emergency problem like engine overheat,
damaged canopy, etc. Minimum safe speed is defined as the stall warning
speed + 10%. If no stall warning system is installed, the minimum safe
speed is the stall speed for the given configu 5KIAS + 10%. For
stall speeds refer to the Aircraft Operating Instructions (Flight Manual)
Section 5 Performance.
4.17.3 Slow Flight Entry
You may enter slow flight from at or above the best endurance speed. If
above, throttle back and as the airspeed bleeds off, raise the nose to
maintain level flight. As the airspeed approaches 46 KIAS increase throttle
to maintain airspeed and level flight. If you start from the best endurance
speed, just pull back on the stick slowly and watch the airspeed bleed off.
As it approaches 46 KIAS increase throttle to maintain airspeed and level
flight. You will need about 5000 RPM to hold the aircraft level and trimming
will help considerably to maintain altitude. If any altitude is lost it will be
very difficult to regain and maximum power may be required.
