PPL Exam
Hi,
I am going over the sample PPL questions at the CASA website and one question has got me banging my head up against a brick wall.
1.6.9.2
"Which of the following is a likely reason for a yaw to the right during the take-off roll in a single-engine aeroplane fitted with an engine which rotates in a clockwise direction when view from the cockpit?"
I also came across the same question in the Bob Tait Practice Exam.
I cannot remember or access the answers for the question.
To the best of my knwoledge, assuming clockwise prop rotation,
Slipstream creates a yaw to the left
Torque - left
Assymetric blade - left yaw
And Gyroscopic effect - left
Any help is apprecited.
Brad

Could I suggest that the gyroscopic effect is to the right, not so noticable on the roll, but on the rotation point.
Effect on the "bottom of the disc",- 6 o'clock position, is for the disc to be "pushed forward", translate that 90 degrees - 9 o'clock position force push to the right, i.e. right yaw.
If that makes sense.
I stand to be corrected.

gyroscopics on rotation are a definate possibility...
if its included in one of the answers- wind from the right hand side causing the plane to weathercock into the wind (ie yaw to the right...)

The 'most Correct' Answer
Remember that often the correct answer is missing. You are then asked to provide the MOST CORRECT answer out of the available choices. This can really do your head in at times.
