Vigil® Cuatro is the most accurate AAD on the market. It becomes armed once 1000 ft above “Ground zero” reference is
reached if no or a positive altitude correction is implemented.
When a negative altitude correction is implemented, the Vigil® Cuatro will become armed 1000 ft above the preset
negative altitude correction, also known as the new landing zone.
The Vigil® Cuatro will not activate below 150 ft above "Ground zero" reference in «PRO», «STUDENT» or «TANDEM» mode
when no or a positive altitude correction is implemented.
When negative altitude correction is implemented, Vigil® Cuatro will not activate below 150 ft above the preset
negative altitude correction in «PRO», «STUDENT» or «TANDEM» mode.
The Vigil® Cuatro will not activate below 300 ft above "Ground zero" reference in «XTREME» mode when no or a
positive altitude correction is implemented.
When negative altitude correction is implemented, Vigil® Cuatro will not activate below 300 ft above the preset
negative altitude correction in «XTREME» mode.
Be aware that any implemented altitude correction will not affect the original “Ground zero" reference altitude.
It will adjust the activation altitude in function of the implemented altitude correction parameters. After such a jump, you need
to switch your Vigil® Cuatro off and back on again to implement the new “Ground zero” reference altitude and manually
remove the previous altitude correction. (If no longer required)


As long as your Vigil® Cuatro is not measuring the switch on pressure or its “Ground zero” reference (90 ft / 27,5 m) it will stay
airborne, (measuring 8 times/sec.) You must ALWAYS switch off your Vigil® Cuatro before any move to another location and switch on
your Vigil® Cuatro at the new take-off zone/location to implement the new “ground zero” reference.

If descending in an aircraft with an armed Vigil® Cuatro , the pilot must be advised of the status of your Vigil® Cuatro to limit his
descent rate according to the mode less than 65 ft/sec. (3900 ft per minute) for “STUDENT” and less than 115 ft/sec.
(6900 ft per minute) for “PRO” or “TANDEM” and in the activation zone (this is especially important for Vigil® Cuatro programmed in
“STUDENT” mode).
In these circumstances we recommend that the Vigil® Cuatro be switched off, if possible.
Prior to opening the door of an aircraft in flight while it is in the activation zone (below 500 m or 1640 ft.), it should be
determined whether or not there are any Vigils on board which are set to «STUDENT» Mode.
Certain aircraft configurations can create a pressure spike which can activate a Vigil® Cuatro AAD, when it is set to
«STUDENT» Mode and the aircraft is in the activation zone.

To avoid unexpected cutter activation, you must switch OFF your Vigil® Cuatro before travelling in a closed vehicle (car,
bus, train ...) or before placing the Vigil® Cuatro in a closed traveling bag, due to possible air pressure variation.
However, there is no problem travelling in an open vehicle at the drop zone altitude.
