(5) Check condition of wing.
(6) Check that canopy fairing on upper wing surface is flush and secure.
(7) Check left fuselage fabric for wear.
e. Nose/Wheel Area:
(1) Check skid and skid plate for security and wear.
(2) Check tow release mechanism wear, condition, and proper engagement.
Inspect release arm and hook for damage, cracks, deformation, and
freedom of movement on pivot bolt. Inspect release arm slot for excessive
wear. Confirm snubber is in place. (Depending on operating conditions,
the unused release mechanism may be secured in place)
(3) Check wheel, tire pressure and brake area for wear, leaks, and condition.
inflation (15 psi if mechanical brakes, 28-30 psi if hydraulic brakes)
(4) Check pitot tubes and static vent for obstructions. Do not blow into the pitot
tube.

3. Some pilots may require seat spacers and cushions to ensure the required sight line
over the nose. Incorrect installation might result in control column interference.

4. VON Marking - Vision Over the Nose (VON) refers to the ability to perform all visual
tasks required for the safe take-off, flight manoeuvres, and landing of an aircraft while acting as
pilot-in-command from the front seat.
(sub paras amended 2016)
5. The ACGP 2-33 requires a VON of 8.1 degrees to enable the front-seat pilot to see the
tow plane while preparing for launch, the tow plane while on tow, most of the tow rope during
tow, and the aiming point on approach; all without looking through the distortion associated with
the lowest portion of the canopy that bends to meet the metal framing.
6. To simplify this requirement and set an
achievable and measurable standard, all
ACGP 2-33 gliders have a VON mark affixed
to the pitot tube IAW Technical Order C-12-
382-000/CF-012. See Figure 3-1.
