Technical General rewards understanding over rote: once you see why a constant-speed unit hunts or why a starboard-turning tendency appears on take-off, half the bank answers itself. Until then, it is 1,626 questions of disciplined repetition across 62 chapters — which is exactly what this bank is built for.
What the bank covers
- Airframes: monocoque and semi-monocoque structure, loads, primary flying controls and trim
- Piston engines: cycles, induction, ignition, cooling, lubrication — and their failure modes
- Gas turbines: compressor, combustor, turbine, propellers and constant-speed units
- Electrics: DC systems, alternators, batteries, bus ties, AC three-phase and protective devices
- Systems: hydraulics, pressurisation, oxygen, fuel, de-icing and the instrument interface
- Applied aerodynamics for the technical paper: stability, control and structure loading
Five questions, exactly as the deck asks them
In a four-stroke engine, the correct order of events is:
- Induction, compression, power, exhaust
- Compression, induction, power, exhaust
- Induction, power, compression, exhaust
- Exhaust, induction, compression, power
Answer: A — Suck, squeeze, bang, blow — the intake, compression, expansion and exhaust strokes in order.
The purpose of a constant-speed unit on a turboprop is to:
- Hold propeller RPM set by the pilot regardless of load
- Limit N1
- Synchronise both engines
- Feather on shutdown
Answer: A — The CSU varies blade angle to hold selected RPM as torque and airload change.
Aircraft DC generators are protected against reverse current by the:
- Voltage regulator
- Reverse-current cut-out (trip lever)
- Circuit breaker
- Bus tie
Answer: B — The cut-out opens when bus voltage exceeds generator output, stopping battery discharge back through the generator.
Engine oil pressure in a well-running piston engine should be:
- Highest at idle
- Lower as oil warms, stabilising in the green band
- Always equal to fuel pressure
- Zero after start
Answer: B — Warm oil thins, so pressure dips then holds in the green arc — a favourite “abnormal reading” question.
Cabin pressurisation is normally controlled by the:
- Outflow valve
- Engine bleed valve
- Pack bypass
- Safety valve
Answer: A — The outflow valve meters air leaving the cabin; the schedule dictates cabin rate of climb.
How to actually clear Technical General
Study system-by-system, not page-by-page: read one chapter (R.K. Bali or your class notes), then drill that chapter the same day. The numerical and failure-mode questions — “what happens if the alternator fails below 10,000 ft” — are the ones that separate 60% from 85%, and the mistakes pool is built for exactly them.
Frequently asked questions
What is covered in DGCA Technical General?
Airframe structure and systems, piston engines, gas-turbine engines, aircraft electrics (DC/AC, batteries, generators), instruments, hydraulics, pressurisation and basic aerodynamics applied to systems. Qwizio Air’s Technical General bank has 1,626 questions across 62 chapters for it.
Is R.K. Bali’s Technical General book enough?
R.K. Bali’s Aircraft Engines & Airframes / Technical General volumes are the common Indian textbooks, and Qwizio Air’s chapters are tagged to that syllabus coverage so you can drill after reading. No text from those books appears in the app — the bank is independent practice material with its own answer keys.
How is Technical General different from Technical Airworthiness?
Technical General (this paper) is about how the aircraft works — structures, engines, systems. Technical Airworthiness is about keeping it legal — maintenance regulations, CARs, logbooks and certification. If your course lists both, check the subject split on dgca.gov.in; Qwizio Air currently covers the five banks listed on this site.
