2 minutes at idle speed.
• Then increase the propeller speed to 1400 rpm until
the oil temperature has reached 50° C and the coolant
temperature has reached 60°C.
2. FADEC and propeller pitch functional check (in
accordance with Section 4.4.1, Page 3 of this Chapter)
3. Check engine acceleration behavior and performance
• Move the load selector quickly to the full-load position.
The propeller must accelerate smoothly and steadily
to the following propeller speed limits (rpm):
Single-engined ........................ 2240 rpm to 2300 rpm
Twin-engined........................... 2240 rpm to 2320 rpm

0.3mm are equivalent to one degree blade angle of the
propeller, one degree is equivalent to a change of 100 rpm.
 Note: CD-155:
