Nick,

All available published data gives 1,000 NM as the maximum range of the
BA609 with an added internal fuel tank. Please advise of the source of
the data that provides other values or states that this is only
available in short take off mode.

You are correct that the weight savings is the smaller part of the
equation. Still this is much higher than most helicopters because of
the need to maintain a CEO level of comfort at 25,000 ft. The major
restriction is in meeting full Cat A.

As I stated before, for government and special civil applications this
restriction can be reduced (ie Coast Guard).

For a fair comparison to the UH-60 military aircraft, can you provide a
source of data that can confirm that the UH-60 meets the latest Cat A
requirements for loads values you are using?

Thanks in advance for providing this information.

Take care,
