Nick,

I spent two hours over the weekend looking for any information
available to show that the UH-60 can comply with FAA Cat A
requirements. No luck what ever. That is why I thought you might be
able to point me in the correct direction with a link or web site.
Especially with your previous company associations.

The extent of BA609 published range data is as follows:

Maximum Cruise Speed 275 kt 509 km/hr
HOGE(ISA, MGW, AEO) 5,000 ft MSL 1,150 m
Service Ceiling (MCP) (All Engines Operating) 25,000 ft 11,364 m
O.E.I. (ISA, MGW) 12,800 ft MSL 3,866 m
Maximum Range * (no reserve) 1,000 nm 1,852 km
* With auxiliary fuel at MTOW-ISA Pending Certification

You indicated that this 1000 NM range was not possible from a hover,
therefore I merely asked for the source of this information.

As you are aware, my current company employment places restrictions on
any information I can devulge. I can direct people to currently
published data, but I am prohibited from releasing any data that has
not been previously cleared for publication.

I do not know what agreements you have with your previous employer, but
based on your status you are most likely under much looser restrictions
than I.

As a constructive recommendation, if Cat A data is not available on the
UH-60, I was going to suggest that you compare the BA609 to the AB139.
Both are modern verticle lift aircraft designed to FAA Cat A. Plus
both use the same PW engines. In this comparison I would concur that
the 750 NM BA609 range should be used. Since adding extra fuel and
droping below Cat A would be unfair to the AB139.

In regards the CH-53 and V-22 comparison, our differences are much
smaller. Therefore I decided to concentrate on areas of your
presentation that I felt did not necessarily represent a fair
comparison.

Thanks in advance again for any information you can direct me to on
UH-60 Cat A capabilities and take BA609 take off hover range
limitations.

Take care,

CTR
