[net.aviation] Question about weight

hsf@hlexa.UUCP (Henry Friedman) (03/19/85)

I'm an aviation novice and haven't followed this group,
but would appreciate an answer to this (possibly dumb) question.

Is there a self-weighing device (say, built into the shocks)
that would give the jetliner crew, before takeoff, an accurate
instrument reading of total loaded weight of aircraft.

Yes, there is, and in fact many of the newer liners have them built in.
If you are obliquely referring to the crash landing of the Air Canada Boeing
757, the plane had the sensors, which are sold by Honeywell. They were not
working correctly, and have been redesigned by Honeywell. On that particular
flight, they were recognized as being inoperable, and a manual fuel measuring
was undertaken.

Question: Do airliners have a device in their landing gear
to measure weight?

The Lockheed L-1011 has exactly such a device which measures
both weight and balance, by measuring the load on each gear.
This is according to an article on the L-1011 by TWA Captain
Barry Schiff, which appeared in AOPA Pilot a year or two ago.
This is apparently a unique feature of this aircraft.

But once when I was I passenger on an L-1011, I visited the
cockpit prior to takeoff, and asked the crew about this device.
They said they kept it turned off because it was unreliable.
