CAAB AME B1.3 Exam Practice Questions - CAAB AME Licence Category B1.3 (Helicopter Turbine) Examination (Bangladesh) Exam - CAAB AME B1.3 Exam Practice Questions - CAAB AME Licence Category B1.3 (Helicopter Turbine) Examination (Bangladesh) Exam

Question 1

What is the primary aerodynamic purpose of main rotor blade twist (washout) on a helicopter?

To decrease rotor tip vortex size and minimize noise signature To produce a more uniform distribution of lift along the span of the blade To increase the structural rigidity of the blade at high rotational speeds To prevent aerodynamic stall on the retreating blade in high-speed forward flight

Correct Answer:

To produce a more uniform distribution of lift along the span of the blade

Question 2

In forward flight, the aerodynamic phenomenon known as 'dissymmetry of lift' is primarily compensated for by which blade action?

Flapping up on the retreating blade and down on the advancing blade Flapping up on the advancing blade and down on the retreating blade Feathering the advancing blade to increase its angle of attack Leading and lagging of both blades simultaneously

Correct Answer:

Flapping up on the advancing blade and down on the retreating blade

Question 3

Which of the following conditions is most likely to initiate 'retreating blade stall' on a helicopter main rotor?

Low gross weight, low density altitude, and high rotor RPM High gross weight, high density altitude, and high forward speed Low gross weight, low density altitude, and low forward speed High gross weight, low density altitude, and low rotor RPM

Correct Answer:

High gross weight, high density altitude, and high forward speed

Question 4

During autorotation, which region of the rotor blade provides the thrust force required to keep the rotor spinning?

The inner 25% of the blade (stall region) The middle 25% to 70% of the blade (driving/autorotative region) The outer 30% of the blade (driven/propeller region) The rotor tip cap assembly only

Correct Answer:

The middle 25% to 70% of the blade (driving/autorotative region)

Question 5

Which combination of parameters is required for a helicopter to enter a Vortex Ring State (settling with power)?

High forward speed, low rate of descent, and engine at idle power Zero or low forward speed, rate of descent exceeding 300-500 fpm, and engine power applied High forward speed, high rate of descent, and engine at maximum power Zero forward speed, vertical climb, and engine at idle power

Correct Answer:

Zero or low forward speed, rate of descent exceeding 300-500 fpm, and engine power applied
