Document Title: AC 119-ANSP
Summary: This AC is essential due to technologies in modern aircraft that may be vulnerable to threats common to IT platforms. Previously, aircraft designers used ARINC 429/629 or MIL-STD data buses to interconnect flight-critical avionics. TCP/IP were used only to support passenger information and entertainment systems. New aircraft designs use TCP/IP technology in a manner that virtually makes the aircraft an airborne interconnected network domain server.

Document Title: AC 61-107B CHG 1, Aircraft Operations at Altitudes Above 25,000 Feet Mean Sea Level or Mach Numbers Greater Than .75
Summary: Individual variability in hypoxia tolerance was the basis of discussions between the National Transportation Safety Board (NTSB) Chief Medical Officer and the Federal Aviation Administration (FAA) about whether to continue to include information in this Advisory Circular (AC) relating to time of useful consciousness (TUC) (a measure of hypoxia tolerance) with increasing operational altitudes. TUCs are based on data that represent average values and reflect wide variation among pilots in terms of time to incapacitation. There was concern that this table was misleading because of the considerable ranges in TUCs given. Rather than delete the table from the AC, we agreed to augment it with more specific information on why hypoxia tolerances vary among individuals. This is in the form of a CAUTION statement presented underneath the original table.
