Legalities
To be legal for IFR, youre supposed to have current charts, under the catch-all “all available information” of FAR 91.103. But its the grayest of gray areas. The dirty little secret is that many pilots ignore this requirement in varying degrees and while we don’t condone this, we cant blame them. The risk of an accident, incident or violation due to expired charts is minimal, but still possible. Sticklers will insist on having the freshest possible nav data and we don’t blame them, either.
But having current charts might not even guarantee that you have the most up-to-date information. Case in point is the Comair crash in Lexington, Kentucky, on August 27, 2006. The crew had the latest IFR charts, but failed to note a NOTAM that pointed out a new taxiway leading to Runway 22, to which they were cleared.
