Choppie - you've got balls, Ill give you that
I stand corrected, they are Tx pumps. It's been a while.
However, when one qualifies on various helicopter as have several contributers on this forum, one realises certain helos can be categorised very quickly into simple and complex.
The Airbus 135 series couldn't be simpler. The fuel system takes about 30 minutes to read about and digest and about the same to operate confidently. Any 'anomolies' (like captions appearing at certain pitch attitudes can, in this particular incident be put down to the 135 being used for police ops - something the designers didn't exactly have at the top of their wish list.
The 'job' causes these 'digresions' from design and consequently the operator has to accomodate them. Hence the switching off, of the Tx pumps during prolonged hover to avoid masking other warnings and to assist with night vision for eg.
It 'appears' that the pilot forgot about them after departure from a previous hover - possibly because they were busy?
Take it from me Choppie - the fuel system on a 135 is/was a doddle. Now would you like to talk about the 101 or S3 or CH47 fuel systems perhaps?
Radio controlled aircraft don't need fuel and Robbo's have elastic bands so those are even simpler to manage
