Sample Technical General questions
A few questions from the bank, with the answer and explanation under each.
1. The correct order of strokes in a four-stroke piston engine is:
- Intake – Power – Compression – Exhaust
- Intake – Compression – Power – Exhaust
- Compression – Intake – Power – Exhaust
- Power – Intake – Compression – Exhaust
Show answer
Correct answer: B. Intake – Compression – Power – Exhaust
Four strokes in order: Intake → Compression → Power (combustion) → Exhaust.
2. The generic spin recovery sequence is:
- Full power, ailerons into the spin, rudder with the rotation
- Power idle, ailerons neutral, full opposite rudder, elevator forward
- Power idle, full aileron opposite, elevator back
- Full power, rudder neutral, elevator forward
Show answer
Correct answer: B. Power idle, ailerons neutral, full opposite rudder, elevator forward
Power to IDLE, ailerons NEUTRAL, FULL OPPOSITE rudder, then push the elevator forward to break the stall.
3. Detonation is:
- Ignition of the charge before the spark
- A violent uncontrolled explosion of the unburnt end-gas after normal ignition
- Normal rapid combustion
- Fuel boiling in the lines
Show answer
Correct answer: B. A violent uncontrolled explosion of the unburnt end-gas after normal ignition
Detonation is the explosive combustion of the remaining 'end gas' due to excessive heat and pressure — causing knocking, power loss and engine damage.
4. Compressor bleed valves are opened at low RPM to:
- Cool the cabin
- Increase axial velocity in the front stages and prevent stall
- Boost thrust
- Reduce EGT at takeoff
Show answer
Correct answer: B. Increase axial velocity in the front stages and prevent stall
Bleeding air from the middle stages keeps the front stages' airflow matched to their blade speed, preventing stall during low RPM and acceleration.
5. An oleo-pneumatic shock strut contains:
- Oil only
- Hydraulic fluid and compressed nitrogen
- Compressed air only
- Rubber blocks
Show answer
Correct answer: B. Hydraulic fluid and compressed nitrogen
Fluid forced through an orifice damps the landing impact; the nitrogen charge acts as the spring supporting the aircraft.
Quick answers
How many Technical General questions are in the Ghost Aviator question bank?
The Technical General bank currently holds 184 questions. Each has one marked correct answer, and an explanation where one has been written. They are split across 36 chapter question pages so you can practise one topic at a time.
Is the Technical General question bank free?
Yes. The questions, answers and explanations are free to read and practise, and you do not need to sign up. Signing in only adds saved progress and attempt history on your dashboard.
What is the DGCA Tech. General paper format?
The DGCA Tech. General paper is 100 questions in 3 hours, passed at 70%, with no negative marking.
How do you know the answers are correct?
Every answer is checked against an authoritative reference, such as a standard ATPL textbook, an ICAO Annex or the relevant DGCA regulation, before it is published. Anything that cannot be verified is flagged or removed rather than guessed.
