AIRCRAFT END-OF-LIFE

G R Mohan | 12:05 AM | | | | Best Blogger Tips



Where do aircraft go when they die? The global aviation sector is expanding at a rapid pace and by 2050; the industry could be handling some 16 billion travellers and 400 million tons of cargo annually. At some stage, maintenance, repair and upgrading become uneconomic and at this point the owner will consider taking the aircraft out of service. It is estimated that over 9,700 aircraft are to be permanently retired or withdrawn from service over the next 20 years. In many cases the retired airframe will contain valuable components and parts that can be returned to 
service.

APPROACH BAN AND CONTINUE APPROACH

G R Mohan | 8:46 AM | | | | | Best Blogger Tips
Here are some ambiguous regulatory provisions. How does one interpret the same? Can a PIC continue with the landing if the required visual references have been established at DA/H or  MDA/H, when reported RVR is below minima? Who is to say that the required visual references have been established and maintained below DA/H or  MDA/H? Will there be a trust deficit issue here ?


EU Ops 1.405
(c) If, after passing the outer marker or equivalent position in accordance with (a) above, the reported RVR/visibility falls below the applicable minimum, the approach may be continued to DA/H or MDA/H.
(e) The approach may be continued below DA/H or MDA/H and the landing may be completed provided that the required visual reference is established at the DA/H or MDA/H and is maintained.





ICAO Annexe 6
4.4.1.3 If, after passing the outer marker fix in case of precision approach, or after descending below 300 m (1 000 ft) above the aerodrome in case of non-precision approach, the reported visibility or controlling RVR falls below the specified minimum, the approach may be continued to DA/H or MDA/H. In any case, an aeroplane shall not continue its approach-to-land at any aerodrome beyond a point at which the limits of the operating minima specified for that aerodrome would be infringed.

Approach ban: If weather deteriorates after an aircraft has passed the approach ban point, the aircraft already on approach may continue to DA (H) or MDA (H).
The approach may be continued below DA(H) or MDA(H) and the landing may be completed provided that the required visual reference is established at the DA(H) or MDA(H) and is maintained.




Indian DGCA CAR  D8O-O2
4.4.1.3 If, after passing the outer marker fix in case of precision approach, or after descending below 300 m (1000 ft) above the aerodrome in case of non- precision approach, the reported visibility or controlling RVR falls below the specified minimum, the approach may be continued to DA/H or MDA/H.
In any case, an aeroplane shall not continue its approach-to-land at any aerodrome beyond a point at which the limits of the operating minima specified for that aerodrome would be infringed.
