NOTE: 1 To ensure recovery by 3000 feet AGL it is recommended that
intentional spins be entered at not less than 5000 feet AGL and in the number of
spin or spiral be limited to 4.
NOTE: 2 Should the propeller stop during a spin proceed in accordance with
procedures for re-starting the engine in flight, Chapter 7 “Emergencies”.
17 Aerobatics
Aerobatics are an outstanding feature of the “Emeraude”. All normal manoeuvres
are permitted as listed on the Aircraft C of A. There is no aerobatic weight
restriction.
The following speeds are recommended:-
Inside loop……………………..120 knots IAS
Slow roll…………………...…..100 knots IAS
Barrel roll…………………..….100 knots IAS
Stall turn………………………...95 knots IAS
Half roll off the loop………..…130 knots IAS
Spins………………………..…slow
deceleration.
When executing manoeuvres in the looping plane do not subject the aircraft to
high (G) loads, (elevator stick force is approximately 10 lbs per “G”)
Throttle back to avoid exceeding rpm limitations
18 Descending
To descend, height may be lost by the conventional power on descent at cruising
speed, or for en route let-down by gliding with the throttle closed.
Before descending check mixture is fully RICH unless carburettor heat is
required in which case adjust accordingly.
Optimum gliding speed, power off at 658 kg max AUW are:-
Clean
……………50
knots
Flaps 20º or 35º …45 knots

20 Approach and Landing
Glide Approach
Reduce speed to 70 knots and lower flap as required. Recommended speed 50
knots IAS flaps up, 45 knots IAS flaps down.
With the throttle closed height is lost quite rapidly.
Ample vision and a good angle of descent is obtained with flaps at 20º.
Full flap may be used if it is desired to steepen the descent still further with no
significant alteration of the landing feel, which is conventional in all cases.
Powered Approach
Reduce Speed to 70 knots IAS and lower flap as before. With power on maintain
45 knots IAS (35º of flap) and regulate rate of descent with the throttle as
required.
