Newcastle EGNT SRA Runway 25

[whatdoesthisbuttondo]

Hi folks, does anyone know why the rwy 25 SRA in NCL has higher MHA by 10 feet when ending at 2 miles (630 ft) than 1 mile (620 feet)

I assume it's something to do with the MAP (which is at 1mile from touchdown) so you have to time it if doing a 2 mile SRA.

Why are there both 2 and 1 mile SRA's to rwy 25 when rwy 07 seems to only have a 2 mile SRA available?

Is it also correct that on termination of an SRA which ends higher than MDA, you can continue down to MDA(H).

Thanks.

At the termination of an SRA (whether that be 0.5, 1, or 2 miles from touchdown) you either have sufficient visual refference to continue the approach visually, or you go-around. Once the SRA has terminated, you have no lateral or horizontal guidance, so unless you are visual, you can't continue.
