Mysterious Codes On Jepp Charts

Sun Aug 08, 2004 5:14 am

For years I've seen the codes on the Airport Diagram charts that list information about each runway in a mysterious format.

Here's an example from the chart for Dulles, my home airport:

RWY 1L-19R
S200, T250, ST175, TT450, DDT875


What do these codes mean and how can I decipher them? Are they related to weight restrictions?

Thanks!

Bryan,

The codes are for the types of landing gear and the weight restrictions for each type.

S= Single
T=Twin
ST= Single Tandem
TT= Twin Tandem
DDT= Double Dual Tandem

The numbers following the gear code is the max weight in 000 of pounds.

Sounds like PCN numbers to me. What part of the Jepp's did you find them in?

875,000 is about as heavy as they get....for the 747-400. I've rarely seen more than that.
