Stalls
=== Stalls ===
==== Approach Stall ====
[[Image:SenecaII_HOWTO_approach_stall.jpg|thumb|The approach stall]]
The first stall to achieve is the approach stall. This is done in approach configuration: gear down, flaps fully set and low power. The goal is to recover from this stall without any altitude loss, because there is no altitude to loose when approaching a runway and getting into a stall 300ft above ground. The stall is indicated by either
* end of white arc on airspeed indicator
* stall warning
* buffeting
whichever is first.
 
Since neither stall warning nor buffeting is currently implemented assume a stall at the end of the white arc (61 knots).
To recover from the approach stall
# Don't reduce pitch!
# full power (40" manifold pressure, 2575 RPM)
# reduce drag
## gear up
## flaps up to first notch
## when stall is broken: flaps up
# accelerate to best rate of climb speed
# reduce power to climb power
<br clear="all">
 
==== Clean Stall ====
[[Image:SenecaII_HOWTO_clean_stall.jpg|thumb|The approach stall]]
Clean stalls happen in clean configuration - flaps up and gear up and reduced power. A altitude loss of up to 100ft is acceptable. Stall indicators are
* end of green arc on airspeed indicator
* stall warning
* buffeting
whichever is first.
 
Recovery is done
# reduce pitch
# full power (40" manifold pressure, 2575 RPM)
# when stall is broken, reduce power to cruise power
<br clear="all">
 
==== Power On Stall ====
[[Image:SenecaII_HOWTO_power_on_stall.jpg|thumb|The approach stall]]
Power on stalls are also in clean configuration but with power either climb or full power. They occur on climbouts on a to high angle of attack. Recovery usually leads to an altitude loss. The stall indicators are
* end of green arc on airspeed indicator
* stall warning
* buffeting
whichever is first.
 
There is only one way to recover from this stall
# reduce pitch
# accelerate
# when stall is broken, continue climb with lower pitch
<br clear="all">
