5420N:
Passing the NDB (LOM) is says 2300. Mapt is 2.1nm further. That is nearly 400ft/nm to achieve 1500ft. That's more than a 3.15 degree slope isn't it?
The descent angle is computed to the runway threshold at a TCH of 53 feet.
Having said that, I don't understand this European system at all, especially where the missed approach point is prior to, and above, the pseudo DA point. The missed approach climbing assumptions in criteria presume a climb at not less than 1,500 and not later than the VOR.
For reference, here is the current Jepp chart. I imagine it is the same as the LIDO chart:
