UK-based aircraft charter and management firm Hangar8 reported yesterday that its overall revenue climbed 39 percent last year to £9.3 million ($14.6 million). This was due in large part to a 118-percent jump in aircraft management fees to £3.7 million ($5.8 million) as the number of managed aircraft rose from 22 in 2010 to 30 last year, with heavy jets accounting for five of the new additions. Charter revenues increased only moderately last year, rising 4 percent to £5.1 million ($8 million). Hangar8 reported a pre-tax profit of £518,000 ($813,260) last year.
