What is the correct statement for the aircraft of the annex?

  • A

    The longitudinal arms for the 11-seat layout are the same as for the 12-seat layout.

  • B

    The longitudinal CGs of the stretchers are more aft than the longitudinal CGs of the middle row of passenger seats of the 11-seat layout.

  • C

    The middle seats of the 12-seat layout have the same longitudinal arm as the medical attendant's seat.

  • D

    The upper and lower stretchers have the same longitudinal arm.

Refer to figure.
'The longitudinal arms for the 11-seat layout are the same as for the 12-seat layout.' → CORRECT.

  • C1 = D1 = 2.86 m (112.6 in)
  • C2 = D2 = 3.64 m (143.3 in)
  • C3 = D3 = 4.35 m (171.3 in)
  • C4 = D4 = 4.4 m (173.2 in)

'The longitudinal CGs of the stretchers are more aft than the longitudinal CGs of the middle row of passenger seats of the 11-seat layout.' → INCORRECT

  • Ambulance Layout Lower Stretchers = A = 3.5 m (137.8 in)
  • Ambulance Layout Upper Stretchers = B = 3.6 m (141.7 in)
  • 11-seat layout middle row of passenger seats = C2 = 3.64 m (143.3 in)

Therefore, the stretchers are more forward than the longitudinal CGs of the middle row of passenger seats of the 11-seat layout.

'The middle seats of the 12-seat layout have the same longitudinal arm as the medical attendant's seat.' → INCORRECT

  • Middle seats of the 12-seat layout = D2 = 3.64 m (143.3 in)
  • Ambulance Layout medical attendant's seat = C = 4.38 m (172.4 in)

'The upper and lower stretchers have the same longitudinal arm.' → INCORRECT

  • Ambulance Layout Lower Stretchers = A = 3.5 m (137.8 in)
  • Ambulance Layout Upper Stretchers = B = 3.6 m (141.7 in)
