fastener 56 the purpose of these stops is to limit the fore aft potential travel of the handgrip 10 as previously explained the present invention offers simulation for afterburner operation however it is desirable to require a handgrip movement in order to simulate handgrip movement which would energize afterburners in an actual aircraft this concern for afterburner energization is due to the fact that fuel consumption is quite high during afterburner operation in order to achieve the required motion a semi cylindrical plate 58 fig2 is coaxially mounted over the body of the friction device 34 it is held in place by means of hose clamps 60 of course other types of securement are quite possible the plate 58 includes a notch 62 that may be characterized as a straight portion connecting to an offset portion 64 it is this offset or zig zag portion which must be traversed by the support shaft 65 of handgrip 10 in order to simulate afterburner operation the handgrip 10 is attached to shaft 65 which in turn is mounted to the upper end of link 43 via a clevis type arrangement which allows it to rotate in a lateral direction about pivot 200 fig2 in addition a spring loaded detent mechanism not shown is mounted on link 43 and causes the handgrip to assume.
