Demonstrate a power and flap stall

 

HASELL checks

 

Ref point – In front of a/c and out your side window Ref Altitude

 

Entry

 

Carb heat to hot

Decrease power to 1500rpm, keeping straight with rudder

In white arc, apply 30° flap

Maintain Ref Alt with elevator

Carb heat cold through 60kts

 

Gently increasing the backpressure to maintain the ref altitude

Keeping straight on the  reference point with rudder

 

Stall

 

Stall recovery

Check forward

Full power, keep straight with rudder on ref point

Raise nose, climb

Raise flap in stages

 

DEMONSTRATION

 

Wing drop stall

Now I am going show you a wing drop stall, so one wing will drop, and in the recovery I am just going to check forward centrally. This will show you what a fully developed wing drop stall looks like.

 

HELL checks

 

Ref point – In front of a/c and out your side window    Ref Altitude

 

Entry

 

Carb heat hot

Decrease power to 1500rpm, keep straight with rudder on ref point

In white arc, apply 30° flap

Maintain Ref Alt with elevator

Carb heat cold through 60kts

Just before stall release rudder pressure

 

Gently increasing that backpressure to maintain the ref altitude

 

Stall

 

Check forward centrally

Note we have lost ……feet, and our direction is significantly lost

 

Climb back up

 

Wing drop stall with minimum altitude loss

 

Now you can see that a wing drop stall could be really dangerous especially close to the ground, this time we will go through the stall again, but this time using the correct recovery technique, so we can minimise our altitude loss.

 

HELL checks

 

Ref point – In front of a/c, and out your side window , Ref Altitude

 

Entry

 

Carb heat hot

Decrease power to 1500rpm, keep straight with rudder on ref point

In white arc, apply 30° flap

Maintain Ref Alt with elevator

Carb heat cold through 60kts

Just before stall release rudder pressure

 

Gently increasing that backpressure to maintain our ref altitude

 

Stall

 

Check forward

Full power

Opposite rudder to prevent further yaw

Wings level, release rudder

Raise nose, climb back to ref alt + ref pt.

 

FOLLOW THROUGH – HELL check

 

STUDENT – HELL check

 

DEMOSTRATION

 

Now just like the previous stalling lessons we looked at recovering at the onset to prevent the actual stall from occurring, so now we will practice these again.

 

Student to set up for another stall, this time recovering at the stall warning (eg)

 

Note:  No stall, No altitude loss, No wing drop
