When did LCN have a name change ?
It didn't, just got replaced by a newer system.
From the
BOEING 777-200 PAVEMENT DATA PDF
The ACN/PCN system (Section 7.9) as referenced in ICAO Annex 14, "Aerodromes," First Edition, July 1990, provides a standardized international airplane/pavement rating system replacing the various S, T, TT, LCN, AUW, ISWL, etc., rating systems used throughout the world.
I'm familiar with the
ACN/PCN system, the
LCG system, and to some extent the
LCN system.
But I'm really confused where an airfield lists Maximum AUW (all up weight in x1000Kgs) dependant upon type of undercarriage assembly. (This applies to most of the airfields in the USA)
The only reference I have decodes the following codes:
S = Single Wheel
T = Twin Wheel
B = Bogie
DB = Double Bogie
But I'm coming across codes such as AUW100S/190D/360DT/550TRT/850DDT
Can anyone decode the following for me?
DT
ST
TT
TDT
DDT
DDB
TRT
Rgds SB777
p.s. which of the codes above would a B777-200 come under?
