No, not that QFE/QNH debate.

Rounding values

One other affecting part is that at least QNH is rounded down to the nearest whole hPa.

Calculation may give more than 3 hpa, but when its rounded down it comes closer to the QFE.

At lower levels it around 27 feet / hPa.
3.74 hpa, after rounding in most cases 3.

Does it have an instrument approach and does the threshold height differ from ARP ?

Edit:
Just looked at the plates:
Airport elevation 101’
Runway 27 = 87’
Runway 09 =. 74’

Problem solved.
Stop edit.

Try calling TWR and get both QFE and QNH in exact value ( including one tenth) and youll see :-)
