Extracts from the RFM

FLOATS

IN FLIGHT PROCEDURES
1. FLOATS EMER switch
Over land operation — Confirm OFF.
Over water operation — Confirm ARMED, FLOAT ARM caution
displayed on CAS.


That cannot be clearer.
TORQUE LIMITER

This extract covers the pre-start checks, collective control switch panel:-

40. ♦ RPM switch (on collective) — Set 100%
41. ♦ 1 ENG GOV (on collective) — AUTO
42. ♦ 2 ENG GOV (on collective) — AUTO
43. ENG TRIM beep switches (on
collective)
— Verify operation, then leave
the engine control levers in
the FLIGHT position.
♦ On BATTERY power use a
single ‘click’ back and forward
to confirm ECL stops in
FLIGHT gate.
Note
Each engine trim beep switch controls the respective
control lever from MIN to FLIGHT position when in
AUTO mode, and from MIN to MAX position when in
MANUAL mode
Note
Both engines control levers should always be operated
through the beep switches located on the collective control.
They should be operated manually only in case of
failure of the remote control (ECL FAIL caution message),
or before starting, to position the lever to FLIGHT.


NOTE - no mention of the TL.
This means that if it was considered 'normal' to use the TL then it would be mentioned - maybe 'Test, then leave on as required' or something similar. The fact that is that it is not mentioned because it is not a normal consideration. As I said before if you can justify the use of the TL in special circumstances then you may have a sound argument in which case you should include it in your (published and approved) SOPs or OM. In my opinion those that fly around with the TL habitually armed are asking for trouble. The TL for OEI ops will always be there whether you like it or not but to loose an airframe for want of worry about an overtorque really is throwing the baby out with the bathwater.
