in why it is done. Thanks
I am not familiar with the potential differences between PANS-OPS and DGCAA. The plate, however, has the PANS-OPS logo printed in the left margin, suggesting that the plate would comply with PANS-OPS regs. I am not sure, but would these minima not refer to failure of DME cases? IAW if your DME fails after you have commenced your final approach (indicated by the Maltese cross) you can go down to 1330', because obstacle clearance is guaranteed to that altitude. If your DME fails after you have passed 3.8 DME you can continue to 780', because obstacle clearance is guaranteed to that altitude. IF your DME fails after 2.8 DME you can continue to 650', because obstacle clearance is guaranteed to that altitude?
