First circuit - Field selection
Where do you join the circuit
Crosswind or early downwind at 500ft AGL
First circuit - Field selection
Cruise type and performance targets
Prec cruise
2100RPM
20* flaps
75KTS cruise
First circuit - Field selection
What’s the next action once stable on down wind
PAX brief
then
BUMFISH
First circuit - Field selection
What also needs to be done on down wind
HHSS
Height - 500ft AGL
Heading - Ref point
Spacing - 2/3 wing strut
Speed - 75Kts
First circuit - Field selection
When do you turn base
As normal, 45* from aim point 1/3 into field
First circuit - Field selection
What is the passover of the field like
Parallel to the field but just off to the right at 500 ft AGL
First circuit - Field selection
What are you looking for going over the field
Wind direction
7 S’s
Obstacle
Time taken to fly over field to estimate length
First circuit - Field selection
How do you judge the length of the field
1/2 GS x time
75kts / 2 =37.5
37.5 x 10 secs = 375m
=38m/s
Second circuit - Low Level Inspection
What’s the type of cruise and performance
Prec cruise
2100RPM
20* flaps
75KTS cruise
Second circuit - Low Level Inspection
Once established on down wind
PAN PAN call
BUMFISH
Second circuit - Low Level Inspection
When to start the descent
Set up a normal descent at 45* point from aim point.
Second circuit - Low Level Inspection
What will the field fly over be like
At 200ft AGL
Roughly halfway between the previous flyover and the runway
Second circuit - Low Level Inspection
What are you looking for during the fly over
Obstacle clearance
Power lines
Surface condition
Third circuit - Practise approach
Once back at 500ft AGL and on downwind what is the type of cruise + performance
Prec cruise
2100RPM
20* flaps

Third circuit - Practise approach
Once on established on downwind
BUMFISH
Third circuit - Practice approach
When turning base
Set up a approach descent by reducing power to 1500RPM
Turn base at 45* from aimpoint
Third circuit - Practise approach
What’s the goal of the approach
Inspection of touchdown zone
Selection of aim point
Approach/departure gradient
Third circuit - Practise approach
At what height do we go around
50ft AGL
Fourth circuit - Landing
What height do you climb to
500ft AGL
Fourth circuit - Landing
When established on down wind and prec search cruise set up what do we do
Another PAX brief
Fourth circuit - Landing
What is done around mid downwind
BUMFISH and HHSS
Fourth circuit - Landing
Conducting a normal circuit pattern after downwind, when do you turn final
To line up on the centre of the field
Fourth circuit - Landing
How should the landing be conducted
Descend to the aim point
Short field approach
