Tulsa, Oklahoma-headquartered Advent Aircraft Systems has received FAA approval to revise the aircraft flight manual for King Air B300/B300C aircraft equipped with the Advent eABS. The STC effort was supported by Textron Aviation, which provided the King Air 350i, flight crew and flight test support under contract with Advent.

The revision offers a reduction of up to seven per cent in take-off field length at typical higher, hotter and/or heavier conditions due to improvements in accelerate-stop performance, with up to 10 per cent available in more extreme conditions. This reduction enables the use of shorter runways for departure, or departing with additional fuel or payload from currently-used runways. The STC also offers a modest reduction in landing distance (up to four per cent) in hot, high and heavy conditions. Though modest, this reduction in landing distance under Part 135 regulations could permit using a 5,000 ft runway.

“This is an important STC for the eABS,” says Advent VP of programmes Don Taylor. “While the primary benefit of eABS for the King Air is overall runway safety and reduced costs, this STC now offers B300 operators additional range, payload and airport options, increasing the usefulness of their aircraft.”

The AFM supplement will be an option for new or current operators of B300/B300C King Airs equipped with eABS. The supplement may be ordered from Textron Aviation service centres, Advent-authorised dealers or Advent Aircraft Systems, and is priced at $2,500.
