Submit your comments via CRT

The objective of this Notice of Proposed Amendment (NPA) is to reflect the state of the art of large aeroplane certification and improve the harmonisation of CS-25 with the Federal Aviation Administration (FAA) regulations. To that end, this NPA proposes amendments to CS-25 following the selection of non-complex, noncontroversial, and mature subjects. 

In particular, this NPA proposes amendments in the following areas: 

Item 1: Go-around handling qualities and performance; 

Item 2: Minimum control speeds; 

Item 3: Fuel tank and system lightning protection; 

Item 4: Cabin safety (various topics); 

Item 5: Electronic AFMs – computation of misleading primary information; 

Item 6: On-board weight and balance systems; 

Item 7: Air conditioning systems; 

Item 8: Flight guidance systems; 

Item 9: Primary flight displays during unusual attitude and declutter modes; 

Item 10: Lightning protection and electrical bonding and protection against static electricity; and 

Item 11: Operation without normal electrical power. 

Overall, these proposals would provide a moderate safety benefit, would have no social or environmental impacts, and would provide some economic benefits by streamlining the certification process.
