Question 1

The engine must not be operated above _______. Doing so will result in abnormal wear on ________, ____________ and ______________, concluding in possible _________________.

However, since instances of inadvertent over speed do occur, it must be emphasized that reporting to the technician in charge is ________ , if RPM exceed _______ for more than _______, or RPM exceed ________ regardless of duration. The maximum RPM and duration of over speed condition should be stated.

Answer 1

The engine must not be operated above 2700 RPM. Doing so will result in abnormal wear on bearings, counterweight rollers and other engine parts, concluding in possible engine failure.

However, since instances of inadvertent over speed do occur, it must be emphasized that reporting to the technician in charge is mandatory, if RPM exceed 2700 for more than 2 sec, or RPM exceed 2730 regardless of duration. The maximum RPM and duration of over speed condition should be stated.

The limiting load factors “G” are 5.4 positive and 2.7 negative.

Question 15

Aerobatic category

Answer 15

The aircraft is in this category when the AUW is less than 900 kg. and the CG is not behind 27.5% MAC and within approved CG-envelope.

Question 16

Aerobatic category maneuvers

Answer 16

In the aerobatic category, the aircraft is limited to the same maneuvers as in utility categories 1 and 2.
The limiting load factors “G” are 6.0 positive and 3.0 negative.

Question 17

Inverted flying

Answer 17

Inverted flying is limited to 10 seconds due to engine oil system design.

During and/or immediately after inverted flying, you may momentarily experience a power loss due to air locks in the fuel system.
