Effect of the "Long Term Solution" Seat Pack on Harvard II (CT156) Aircrew Accommodation
Abstract
The requirement to include additional survival equipment as part of the seat survival kit of the Harvard II has caused a significant increase to the seat thickness (4 to 5 cm). A previous study determined that any increase in seat thickness would likely have repercussions on the ability of the taller individuals to see all of the information displayed by the Electronic Attitude Director Indicator (EADI), on control stick authority, and possibly on helmet to canopy clearance. The object of this study was to assess the impact of this new seat pack, or Long Term Solution (LTS) seat pack, on pilot accommodation. The study found that approximately 12% to 17% of student pilots (i.e. individuals in the front seat) would not be able to see all of the EADI information. In addition, the taller 2% to 3% of pilots would likely exceed the aircraft's maximum sitting height limits and have insufficient clearance between the top of the helmet and the canopy. Stick authority was relatively little affected by the proposed seat compared to the baseline. Removal of the g-suit from the winter clothing configuration significantly improved stick authority.
