S. 72 : Since military and civil flying cannot both be fully developed at Whenuapai, and the aerodrome cannot be made to satisfy 1.C.A.0. Class 4 Standards, we consider that a new international airport is necessary at Auckland. We recommend urgent investigation of sites at Mangere and Pakuranga and the provision of funds for the necessary meteorological and engineering surveys. (Paragraphs 259-264.) S. 73: We recommend that instrument landing systems and approach and runway lighting should be installed at Ohakea and Whenuapai. (Paragraphs 265-266.) 5. 74: Rongotai could not be developed as an international aerodrome because of the surrounding hills. Paraparaumu could not be made to comply fully with international standards because of the hills on one side. We do not consider there is a case for making an international aerodrome, to serve Wellington, further away from the city. (Paragraphs 267-268.) 5. 75 : Harewood is suitable for the development of an international aerodrome for Christchurch. The Royal New Zealand Air Force aerodrome at Wigram is too close to permit the development of both, and either a decision should be taken to move the Air Force ultimately to another aerodrome or a new site should be chosen and developed now as the civil airport. (Paragraphs 269-276.) S. 76: The reports on which Wellington Harbour was condemned for flying-boat operation are not applicable to modern flying-boats. We believe that examination and trial by seaplane operational experts would prove it to be suitable for modern flying-boats. (Paragraphs 277-279.) Internal aerodromes S. 77 : The practical limit of construction at Rongotai appears to be 1.C.A.0. Class E. This limits the classes of aircraft which may use it. We disagree with the proposal that initial construction should be limited to a strip width of 300 feet. The minimum strip width for safety should be 500 feet, with a clearance of houses over a total width of 800 feet. Full development will necessitate the clearance of the whole isthmus. Plans for the road subway should be reviewed accordingly. When Rongotai aerodrome is constructed, the need for further development of Paraparaumu will disappear. (Paragraphs 284-286.) S. 78: Runways are required at Palmerston North. (Paragraph 287.) S. 79: The economy of air transport and-of aerodrome operation dictate that two towns situated as are Hastings and Napier should, if practicable, be served by one suitably located aerodrome. (Paragraphs 288-290.) 5. 80: Dunedin (Taieri) aerodrome is unsuitably situated for the operation of scheduled air services and involves considerable risk. Investigation of a new site in the Taieri Valley is recommended. (Paragraphs 291-293.) 5. 81: Otago Harbour is suitable only for the operation of small seaplanes. (Paragraphs 294-295.) 5. 82: In Central Otago, it is recommended that an aerodrome of 1.C.A.0. Class E Standard for the operation of scheduled air servicfes be developed at Alexandra. Other towns should have smaller aerodromes for the operation of light aircraft. (Paragraph 296.)
