Sample SHGM ATPL(H) Practice Questions

Try these sample questions to review concepts for the SHGM ATPL(H) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 28+ question experience with AI tutoring.

1An ATC clearance conflicts with a helicopter's flight manual limitation. What should the commander do?
A.Accept it because ATC has assessed aircraft performance
B.Explain the limitation and request an alternative clearance
C.Comply if both pilots agree
D.Comply while recording the exceedance
Explanation: An ATC clearance does not authorize exceeding aircraft limitations. The commander must communicate the inability and obtain a safe alternative.
2Does successful ATPL(H) theory automatically grant an instrument rating or complete ATPL(H) licensing?
A.Yes, both are included
B.It grants the licence but not the rating
C.No; applicable training, experience, ratings and skill tests remain separate requirements
D.It grants the rating but not the licence
Explanation: SHT-FCL treats theoretical knowledge as one part of licensing. ATPL(H) and ATPL(H)/IR routes must be distinguished, including their applicable instrument and practical requirements.
3In a free-power turboshaft, how does the gas generator transfer energy to the power turbine?
A.Through a common rigid shaft
B.Through an overrunning clutch between both turbine shafts
C.Through expanding combustion gases, without a direct shaft connection
D.Through the main gearbox lubrication pump
Explanation: The gas generator drives its compressor on its own shaft. Its gas stream drives the mechanically independent power turbine, which supplies transmission power.
4A transmission filter bypass warning appears. Why can lubrication continue while the condition still requires prompt checklist action?
A.Bypass flow restores filtration
B.Bypass flow preserves oil delivery but may carry contamination
C.The bypass removes the gearbox load
D.The warning indicates only an oil-temperature sensor fault
Explanation: A bypass can preserve oil flow when a filter restriction becomes excessive. It sacrifices filtration, so continued flow does not establish that the transmission is healthy.
5Which control channel is added by a four-axis helicopter automatic flight control system to pitch, roll and yaw?
A.Collective
B.Rotor brake
C.Engine start
D.Landing gear
Explanation: The fourth axis controls collective pitch and thus total rotor thrust. Its available vertical guidance modes depend on the installed system and selected mode.
6A radio altimeter shows decreasing height during an offshore approach while barometric altitude is steady. What is the best interpretation?
A.The radio altimeter must have failed
B.QNH must have changed
C.A rising underlying surface or differing measurement references could explain the disagreement
D.The helicopter must be descending at the radio-height rate
Explanation: Radio altitude references the reflecting surface beneath the helicopter, while barometric altitude references a pressure datum. Compare terrain, platform geometry and instrument validity before diagnosing a failure.
7A helicopter's mass is 3,000 kg at arm 3.00 m. A 200 kg load is added at arm 4.00 m. What is the resulting longitudinal CG?
A.3.250 m
B.3.063 m
C.3.500 m
D.2.938 m
Explanation: The new moment is 3,000 × 3.00 + 200 × 4.00 = 9,800 kg·m. Dividing by 3,200 kg gives 3.0625 m, rounded to 3.063 m.
8A 2,500 kg helicopter has CG 2.95 m aft of datum. To reach a forward limit at 3.00 m, ballast is added at 5.00 m. What minimum ballast mass is required?
A.25 kg
B.41.7 kg
C.50 kg
D.62.5 kg
Explanation: Let ballast mass be b: (2,500 × 2.95 + 5b)/(2,500 + b) = 3.00. Therefore 2b = 125 and b = 62.5 kg; aircraft mass limits must also be checked.
9At the planned conditions, an RFM gives HIGE mass capability 4,800 kg and HOGE capability 4,400 kg. Actual mass is 4,600 kg. What does this establish?
A.Both hover conditions are available
B.HOGE is available but HIGE is not
C.HIGE is available, but HOGE is not demonstrated by these data
D.Neither hover condition is available
Explanation: The actual mass is below the stated HIGE capability but above the HOGE capability. Ground-effect hover capability cannot be substituted for out-of-ground-effect capability.
10An OEI climb achieves 300 ft/min at a groundspeed of 60 kt. Using 1 NM = 6,000 ft for this exercise, what is the climb gradient?
A.3%
B.5%
C.10%
D.20%
Explanation: At 60 kt the helicopter travels 1 NM, or the supplied 6,000 ft, each minute. Gradient is 300/6,000 × 100 = 5%, independent of how the climb is labelled operationally.
