Unless the airspeed indicator in the helicopter is connected to
something in addition to the pitot system (ie: normally a single line
connected to the rear of the airspeed indicator), you should be able to
replace it with and it will simply work.

Subject: Yak-List: airspeed indicators
In the Mi-2 helicopters we are restoring the airspeed indicators go to
500 km/hr even though Vne is something more like 200 km/hr. My friend
said this was like his old car that had a speedometer that went to 160
even though the car was scary at 80 mph. :-)
The short question is if we replace these with airspeed indicators
that go to maybe 120 knots (apparently helicopter pilots can only think
in knots), will they simply work, or are airspeed indicators matched to
the air system in an aircraft?
Obviously the other choice is to simply reface them, but everybody
agrees that an airspeed that goes to less than half the gauge for Vne
seems like a waste of a lot of dial space.

I'm almost positive you can go with any airspeed indicator. The ASI
measures pressure and is simply calibrated to indicate whatever pressure
it sees. In my Yak-50 is an ASI that measures all the way out to 1100 km/h
(or something ridiculous for a Yak). It is from a a MiG. It works just
fine.
How long 'til the helicopter flies??

First Mi-2 helicopter has its airworthiness=2C has flown off phase I=2C and
goes to its first airshow this weekend!
Both Mi-24s have had all but 4 (2 each) of their *60* hoses (fuel=2C oil=2C
hydraulic=2C whatnot) replaced (all braided stainless "forever" hoses -- p
rice = ouch). Waiting on the 4 hoses and then a little weight and balanc
e jigging (or! anybody just happen to have a mock-up of the quad 12.7mm Yak
-B Gatling gun?) and it's off to the races with the FAA. Unfortunately the
only date we have on the hoses is "soon". :-)

JB, The A/S indicator in a helicopter works exactly the same as in a fixed
wing platform.=C2- Ram air and static pressure.=C2- When I was in A&P S
chool, we took the A/S indicator out of an old Bell 47 (of MASH fame)=C2-
and installed it in J-3 Cub while we were waiting on a new indicator for th
e Cub.=C2- The one difference b/w helicopter ops and fixed wing ops with
respect to A/S indications is placement of the pitot tube and indications a
t a hover.=C2- Sometimes, at a hover, one will see the airspeed needle ju
mp around because of the induced flow being ingested by the pitot tube.=C2
- Otherwise - same same GI.=C2- JB (Jon Blake)
