NCAA PPL (Helicopter) Theory Exam study guide
NCAA PPL (Helicopter) Theory Exam · Work through your exam, one topic at a time.
The NCAA PPL (Helicopter) Theory Exam is the ground-examination stage of the private pilot licence for helicopters, delivered in nine subject papers that mirror the standard EASA-style PPL(H) syllabus: air law, helicopter general knowledge, flight performance and planning, human performance, meteorology, navigation, operational procedures, principles of flight, and VHF radiotelephony. It is aimed at student pilots who have begun flight training or intend to, and who need to demonstrate ground knowledge before or alongside their flying hours. The NCAA PPL (Helicopter) Theory Exam study guide has 9 sections and about 2,152 words.
01Air Law and Operational Procedures - PPL(H)
This domain tests the legal framework a private helicopter pilot must apply: licence privileges, documents, rules of the air, minimum heights, right-of-way and flight-plan/NOTAM awareness. It is not a memory test of regulation numbers; it asks whether a proposed flight is lawful and safe.
330 words, about 2 min02Helicopter General Knowledge - Airframe, Systems, Rotor Dynamics and Powerplant
This domain tests how the helicopter is built and how its systems interact: rotor head type, controls, transmission, engine, hydraulics, electrical supply and the dynamic behaviour that limits the machine. A fully articulated head has flapping hinges, lead-lag hinges and feathering bearings; a semi-rigid head teeters as a unit; a rigid head relies on blade flexibility.
300 words, about 2 min03Helicopter Flight Performance and Planning - Mass, Balance and Performance
This domain tests whether the helicopter can safely lift the load, keep the centre of gravity within limits and perform in the prevailing density altitude, wind and surface conditions. Use datum, arm and moment.
274 words, about 1 min04Human Performance and Limitations
This domain tests the pilot as a system: hypoxia, hyperventilation, spatial disorientation, fatigue, stress, vision, hearing, alcohol/drugs, medical fitness and decision-making. Helicopter work adds vibration, noise, confined cockpits and low-level visual illusions.
241 words, about 1 min05Meteorology
This domain tests weather knowledge for low-level helicopter operations: pressure, density altitude, wind, turbulence, icing, fog, thunderstorms, fronts and METAR/TAF interpretation. QNH is pressure reduced to mean sea level; QFE is pressure at the aerodrome.
209 words, about 1 min06Navigation
This domain tests dead reckoning, charts, heading and track, wind triangle, magnetic variation/deviation, time/fuel planning and GPS use. True course is measured on the chart; true heading corrects for wind; magnetic heading applies variation; compass heading applies deviation.
202 words, about 1 min07Operational Procedures
This domain tests standard helicopter operations: pre-flight, passenger briefing, fuel management, confined areas, slopes, pinnacles, autorotation, emergencies and radio failure. Pre-flight includes documents, mass and balance, fuel, performance, weather and NOTAMs.
197 words, under 1 min08Principles of Flight - Helicopter Aerodynamics
This domain tests lift, drag, rotor-disc behaviour, translational lift, autorotation, vortex-ring state and retreating-blade stall. Relative airflow and angle of attack produce lift; induced drag increases with lift, profile drag increases with speed.
233 words, about 1 min09Communications - VHF Radiotelephony
This domain tests standard VHF RT: phraseology, readback, distress and urgency calls, position reports and lost-communication actions. Use the phonetic alphabet and standard words: ‘roger’, ‘wilco’, ‘affirm’, ‘negative’, ‘standby’, ‘say again’.
