If you refer to CAP 168 Chapter 3, para 4.3.3 (runway strip width), you will see that it states"....when the highest value of TODA or ASDA falls into the bottom third of code number 3 the width for a non-precision runway strip may be reduced to not less than 105m either side of the centreline....".
LCY is a code 3 aerodrome which presumably takes advantage of this rule as their TODA & ASDA is less than 1400m. I do not, however, understand how their runway is classified as 'non-precision' as it has CAT 1 ILS. Or is a CAT 1 ILS runway just an 'instrument runway' and not a 'precision approach runway' thus allowing LCY to benefit from this rule?
The apron manoeuvering area would also seem to impinge on the runway strip width, which I did not think was permitted.
I, likewise, am not trying to 'knock' LCY but just wonder if it operates under some form of derogation of the regulations due to the physical limitations of the site.
Can anyone shed any light of this apparent anomaly?
