Use Of Reverse Thrust & Wet Runway
I wonder if anyone can help, specifically, with regards to the origins of a statement I have found in a company (not ours, duing audit) operations manual.
USE OF REVERSE THRUST
Note: Reverse thrust should be used as indicated in type specific
manuals.
It should be noted that safety levels are likely to be affected to an
unacceptable extent if reverse thrust is not selected when:
1. The runway is wet and the landing distance is less than 140% of
the landing distance required.
Now my company does not take credit for use of reverse thrust on dry/wet runways as per EU-ops and I cannot find any reference to the above in EU-Ops (JAR-Ops) or the aircraft manufacturers data. I 'think' the CAA used to allow credit for reverse thrust on dry/wet runways when certifying data, prior to EU/JAR-OPS but this is a very faint memory as I have not been around that long (honestly!).
Can anyone help?> I really hope that John Tull or Old Smokey might be woken up to have a pitch at this for me!
with thanks to all
