6.5.5 EMERGENCY DESCENT CONTROLLED FROM THE GROUND USING THE
HAND PUMP IN THE EVENT OF FAULTS ON ALL ENERGY SUPPLY SYSTEMS

and place it in the corresponding adjusting screw (see photo) located in the proportional
valve compartment;
‑ move the switch located on the hand pump to the position corre‑
sponding to movement of the aerial part;
‑ tighten the knob completely;
‑ Withdraw the key enabling the emergency descent and a key ope‑
ning the distributor controls’ protection, if any, from the engine keys
group inside the electrical components compartment;
