==== 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 | |||

==== 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 | |||
