is somewhat roomier in the L-23, and some differences are a swept fin and a T-tail, and on the L-23 flaps were deleted to save weight since they were rarely used on the LET L-13. The airbrakes were retained however, and these open on both the top and the bottom of each wing. LET also moved the tailplane to the top of the vertical stabilizer for better protection in case of an outlanding. It also has a new instrument suite. The aircraft has a two-piece canopy, where the front part opens to the right, and the rear part opens upwards and to the rear. This was done to improve vision compared to the L-13. From serial No. 968401 it was delivered with a one-piece canopy, that opens to the right only (with a very small canopy section opening to the rear at the wing root). The maximum number of occupants is two. If it is to be flown solo, the pilot must be sitting in the front seat and his weight (including

A weighted seat weighing 15 kg (33 lb) is available to replace the soft seat cushion bottom in the front seat. The United States Air Force Auxiliary
