CR. LTH-1 Advantages

The advantages of the concept so evolved and preserved throughout the development work, in the light of its achievements and planned consequences, are summarised below: 

1. Twin-engine safety up to Transport Group A (Category A) standard. 
2. Operational flexibility through unrestricted over-city, over-water and low-level flying, and operation from "tennis court" sites. 
3. Low cost in production and operation. 
4. There are no power losses to a tail rotor. 
5. Increased hovering efficiency due to close rotor separation. 
6. Aerodynamic rotor efficiency due to close rotor separation. 
7. Streamlining is effective with no loss of accessibility. 
8. All control effects are totally independent and fully symmetrical. 
9. The two-bladed rotors assist ground handling and storage in limited areas. 
10. The absence of a tail rotor eliminated a notorious hazard on the ground. 
11. Rationalised design of airframe and systems achieves servicing economy and minimises essential spares. 
12. Simplified servicing/overhaul procedures. 
13. The entire mechanical system is built as a compact central unit, readily installed and maintained. 
14. Reduced noise level. 
15. Easy conversion within a choice of various operational roles. 
16. Easy adaptability to many layouts, types of engines and special purposes is achieved. 
17. Advanced development potential in terms of simplicity, speed, and flight handling qualities is inherent in the configuration.
