Operational Test - Magni Gyro M16C Ordinary Maintenance Manual

3.2.3 EFFICIENCY TEST:
(See Fig. 3.2/1 ‐ 3.2/5)
WARNING DANGER:
An operational test of the system is strongly recommended before starting to fly. Excessive shimming
(between the pre‐rotation assembly pn 117 and the support pn 120) could prevent the disengagement
of the power transmission when the pre‐rotation control lever pn 415 is released, thus generating
hazardous consequences! Two people are needed to execute this test: a qualified gyroplane pilot that
knows the pre‐rotation procedures and an outside observer that will always keep outside the rotor
range area!
WARNING DANGER:
1. Before starting the engine make sure that there are no obstacles, people or objects within the
rotor range area as too much shimming may result in an immediate rotation of the rotor upon
engine start up!
2. Start the engine, following the standard start procedure;
3. Warm up the engine taking it to minimum operational temperature;
4. Set engine to 1800 r.p.m. rotation speed;
5. Gently engage the pre‐rotation. Keep in mind that the coupling will happen in advance;
6. Keep the engine setting to 1800 r.p.m. and gently push the pre‐rotation control lever pn 415 until it
reaches the end of its run. Verify the number of the rotor revolutions achievable with this engine speed.
In optimum conditions, it should easily exceed 160 rotor r.p.m.;
7. When the number of rotor revolutions stops increasing, gently increase the engine revolutions till 200
rotor r.p.m. are reached (approx 2.200‐2.400 engine r.p.m.);
8. Release the pre‐rotation control lever pn 415;
