During a functional check of a stall-warning tone amplifier on a light piston aeroplane, audio input is confirmed present and board supply is correct. On the grounded-emitter NPN output stage, the technician measures base at 0.72 V, emitter at 0 V, and collector at the full supply rail. No tone is produced. What is the most likely fault?

Feedback from learners using Aviation Conquer to make UK CAA Part 66 Aircraft Maintenance License preparation more focused and manageable.
4.9/5
from 400+ reviews
Nadia F.
Aviation Conquer learner
“While preparing for B3, I keep a small list of mistakes from Aircraft Materials, Hardware, and Maintenance Practices. Reviewing why each answer went wrong keeps my study sessions more focused than simply rereading notes.”
Jonas P.
Aviation Conquer learner
“Great B3 prep. Aviation Conquer was clear and easy to use!”
Rosa M.
Aviation Conquer learner
“For B3, Piston Aeroplane Aerodynamics and Structures was the area I kept postponing. Breaking it into a few practice questions at a time makes the material much easier to revisit after work.”
Jamal W.
Aviation Conquer learner
“My B3 routine is simple: one timed set, a short break, then a careful review of Piston Engine and Propeller Systems. The explanations show whether I understood the idea or just guessed well.”
Yuki S.
Aviation Conquer learner
“The B3 practice questions kept my review focused.”
Trevor B.
Aviation Conquer learner
“I use lunch breaks to review Aviation Legislation and Human Factors for B3. Short sessions work better for me because I can focus on one weak area without trying to cover the whole syllabus at once.”
Hannah T.
Aviation Conquer learner
“The hardest part of B3 prep for me is keeping similar ideas in Mathematics and Physics for Aircraft Maintenance separate. I now write one-line comparisons after each practice set, which makes the next review much clearer.”
Elena G.
Aviation Conquer learner
“Aviation Conquer made B3 prep simple and easy to follow.”
Aisha M.
Aviation Conquer learner
“I am still working through B3, especially Electrical and Electronic Fundamentals. Going back through missed questions slowly has shown me which details I rush past when I practice under time pressure.”
Maya R.
Aviation Conquer learner
“B3 review felt much more manageable with these tools.”
Recorded customer testimonials
“the practice questions are helpful similar to the topics covered in the real exams i love the detailed explanation provided right after each question”
“The practice questions, key study notes, and supportive staff all help me pass the exam. The best thing is the questions are well structured and similar to the ones on the exam.”
“The well-structured practice questions help me prepare for the exam conveniently.”
“The practice questions are superbly crafted, making exam preparation a breeze. The explanations provided after this question are like gold dust.”
“Thanks to the well-organized practice questions, I was able to tackle my exam preparations with ease. The questions are thoughtfully designed to closely resemble those in the actual exam.”
“the practice questions are incredibly helpful, closely resembling the real exam scenarios. There are very detailed explanations provided and actually studying has never been this efficient.”
“Can’t I Just Study on My Own?”
Of course you can. Any exam can be prepared for independently. But you’ll spend weeks extracting key concepts from dense manuals, guessing which topics are actually tested, and hoping you covered enough.
Or you can let our full-time exam team do that heavy work for you — so you can focus on practice, pass on your first attempt, and spend your evenings with friends and family instead of buried in textbooks.
- Syllabus already distilled into study notes
- Skip weeks of sorting through manuals

Do all questions come with explanations?

How do I get access after payment?
Full premium content is available immediately after payment is confirmed.
Is this a one-off payment or a subscription?
Every plan is a one-off payment. There are no recurring charges, no auto-renewals, and no subscriptions — you pay once and keep full access for the term you chose.

What is spaced repetition?
Spaced repetition brings weak topics and flashcards back at planned intervals to support long-term recall before exam day.
What is the Exam Readiness Score?
Your dashboard tracks accuracy, pacing, and topic-by-topic mastery across everything you answer, then summarises it as a readiness indicator so you can see which areas still need work before you book the exam.
How does the wrong-answer bank work?
Every question you get wrong is collected automatically into a dedicated review set, so you can retrain exactly the items you missed rather than repeating questions you already know.
