Hi,
whith so much knowlede about Pumas here, I would like to forward a question from a model builder, which I couldnīt answer, cause I fly different helicopters...
For a stand up model with "animation" he would like to know, how the lights are operated in and out and in which direktion the main rotor turns viewed from above.
about the lights, he wants to know about the interior lightning, signal lights, colors of the lights, landing lights, frequenzy of the strobes and anti colision light.
Photos would help him (yes, he could google - but Iīm sure, you have better stuff - donīt you?)

BIMS
I was once despatched from Odiham to take an HC1 to Aerospatiale Marignane (Sp?) to collect some new door rails that would hopefully prevent the doors falling off in-flight. Our aircraft had an F700 entry on the BIMS that limited us to 30 minute sectors between shutdown external checks. Luckily, we went U/S near Guildford for some reason and that was the end of what would have been a very tedious flight!

The Puma HC1;1971-1978. The 330J; 1978-1982. The 332L/1; 1981-2008.
A Cat; British, Australian and Chinese licenses.
They were modified after the Belize crash in 1976. This is Shy Torque's post on that thread which describes it.

The Pumas electrical system was modified after this accident. The normal main rotor speed (Nr) limits were 258 to 272. If the Nr dropped to 240 for 2 seconds, the alternators tripped off. The system was modified to remain on unless the Nr dropped to 220.QUOTE]
Up to that point if an engine failure occurred at a heavy weight and high power demand the rotor would droop more rapidly than one could be expected to correct for it. Later Pumas with the Makila could cause no more concern than a decibel failure on one side.
