Measurements on all the Runway length:
a.- (1) in Center Line
b.- (10) at 2, 4, 6, 8 and 10 meters on each side covering 20 m width
c.- Once a year evaluation
1) Until 1990, the official standard in Mexico had a maximum
Value of P. I. = 30 inch/mile (47 cm/Km)
2) From 1992, the standard value was improved requiring a maximum P. I. = 15 inch/mile (24 cm/Km)
3) The new mexican proposal (2007) now in study and discussion, we expect to have it approved along 2008 and will require for all medium and large airports a maximum “Profile Index of 10,0 and 15,0 cm/Km”
