A question I could not find any reference to in the ATC books any help would be great

To ensure obstacle clearance during a missed approach on a certain runway a climb gradient of 3.2% is required, the least rate of climb required to ensure obstacle clearance for a aircraft climbing at 80kts IAS during a missed approach is
A) 320
b) 250
C) 256
D) 500

Those figures are fpm

3.2% X 80= 256

So answer C
Its just gradient by groundspeed, they might try and trick you giving an IAS and a wind component later on.

Although you probably can't take the DAPs into a CPL exam......
