All the best. Name 1. What is the temperature in comparison to ISA conditions at 30,000ft? 0°C -60°C -45°C None 2. In the ISA the height of the tropopause is 11,000 feet 36,000 metres 11,000 metres None 3. A High Aspect Ratio wing is a wing with long span, short chord long span, long chord short span, long chord None 4. At what altitude is the tropopause? 36,000 ft 57,000 ft 63,000 ft None 5. Profile drag consists of what drag types? Form, induced and skin friction Form, skin friction and interference Form, induced and interference None 6. The lift curve for a delta wing is more steep than that of a high aspect ratio wing the same as that of a high aspect ratio wing less steep than that of a high aspect ratio wing None 7. If fluid flow through a venturi is said to be incompressible, the speed of the flow increases at the throat to maintain a constant volume flow rate allow for an increase in static pressure allow for a reduction in static pressure None 8. QFE is difference between sea level and airfield pressure airfield pressure sea level pressure None 9. As the angle of attack increases the stagnation point does not move moves towards the upper surface moves towards the lower surface None 10. Induced drag increases with an increase in speed increases with increase in aircraft weight reduces with an increase in angle of attack None 11. The stagnation point is static pressure plus dynamic pressure dynamic pressure only static pressure minus dynamic pressure None 12. Which has the greater density? Air at low altitude It remains constant Air at high altitude None 13. The 'wing setting angle' is commonly known as angle of dihedral angle of attack angle of incidence None 14. Lift on a delta wing aircraft decreases with an increase in angle of incidence (angle of attack) increases with an increased angle of incidence (angle of attack) does not change with a change in angle of incidence (angle of attack) None 15. "What is the collective term for the fin and rudder and other surfaces aft of the centre of gravity that helps directional stability?" Empennage Fuselage surfaces Effective keel surface None 16. Which of the following is true? Lift acts at right angles to the relative air flow and weight acts at right angles to the aircraft centre line Lift acts at right angles to the wing chord line and weight acts vertically down Lift acts at right angles to the relative airflow and weight acts vertically down None 17. Which is the ratio of the water vapour actually present in the atmosphere to the amount that would be present if the air were saturated at the prevailing temperature and pressure? Dew point Relative humidity Absolute humidity None 18. Density changes with altitude at a rate which is constant until 11 km of 2kg/m3 per 1000 ft which changes with altitude None 19. A delta wing has a lower stall angle than a straight wing a higher stall angle than a straight wing the same stall angle than a straight wing None 20. Which of the following is correct? Absolute pressure + Atmospheric pressure = Gauge pressure Absolute pressure = Gauge pressure + Atmospheric pressure Atmospheric pressure = Absolute pressure + Gauge pressure None 1 out of 1
