CitationShares, the fractional aircraft ownership venture between Cessna and TAG Aviation USA, claims to be the first fractional operator whose aircraft are all RVSM-compliant. CitationShares currently operates 34 CJ1s, Bravos and Excels for some 300 owners. The Greenwich, Conn.-based company also said all 140 of its pilots are RVSM-qualified. A company spokesman said that all its aircraft are delivered from Cessna with RVSM certification.
