WARNING
Exceeding the flight parameters may severely damage
the main rotor assembly of the damaged helicopter,
requiring component replacement. Report the amount
and duration of any flight parameter exceeded to the
unit responsible for the damaged helicopter.
The height above ground level may be difficult to
determine during low-level UMARK operations due to
the length of the sling system. Flight crews should
exercise extreme caution during recovery operations
to ensure the damaged helicopter remains clear of
ground obstacles.
4. COMPONENTS REQUIRED
Components of UMARK utilized during the one-hook, short-line recovery are listed in Table 2. Common
equipment used by the ground rigging crew, such as shockproof gloves, goggles, radios, etc., are not included in
