040071 · Turbine Engines and Propellers
In a turbojet's vibration monitoring system, any vibration the engine produces is:
- Adirectly proportional to engine speed
- Bsent straight to the cockpit indicator with no amplification or filtering
- Camplified and filtered before being sent to the cockpit indicator
- Dinversely proportional to engine speed
Why that is the answer
Raw vibration signals picked up by accelerometers on a turbojet contain a wide range of frequencies and amplitudes generated by rotating components, structural resonances and aerodynamic noise. If fed directly to the cockpit gauge, this raw signal would be noisy, difficult to interpret and prone to false indications. Engine vibration monitoring systems therefore process the transducer signal through amplification (to bring the weak sensor output to a usable level) and filtering (to isolate the frequency band associated with genuine rotor imbalance or engine-related vibration, rejecting irrelevant noise) before it reaches the cockpit indicator. Option a and d wrongly assert a simple proportional or inverse relationship with engine speed, which ignores that vibration amplitude depends on many factors besides RPM. Option b is incorrect because unprocessed signals would make the indication meaningless to the crew; amplification and filtering are essential steps in the signal chain.

Frequently asked
How many Turbine Engines and Propellers questions are there for the DGCA CPL Technical General paper?
Avielevate's bank carries 35 published Turbine Engines and Propellers questions for Technical General, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
How much of the Technical General paper is Turbine Engines and Propellers?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise Turbine Engines and Propellers?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
