The Instrument you can live without

If you were about to go on an IFR flight, and for some unknown,
hypothetical reason you had to pick one instrument in the standard six
pack that you could not use, which one would it be?

The DG. Mag compass (not to mention GPS) can be uesd as a backup. If wings
are level and the compass isn't moving, I'm ok on direction and bank.

I second that. The altimeter is more than adequate as a backup for the
VSI. And when you're trying to damp out phugoid oscillations the
altimeter is actually better than the VSI for judging ascent/descent
because the VSI lags.

I've lots the airspeed indicator in IMC twice now and didn't find it
effected the flight awhole lot. Both times were during climb out into
low IMC (stuck spring cover). However, if I had to pick, I'd probably
take the VSI. Nowadays with ok GPS altitude you could also lose the
alitimeter and make a reasonable attempt with the GPS altitude after
figuring out the difference from ATC's mode C response.

The VSI only lags in giving a RATE of climb/descent. In smooth air, or
smooth pilot inputs, the VSI will give nearly immediate response up or
down.
I could live without the VSI, or the AI, or DG, and make do with the
rest of them and do a decent approach. I began teaching what I call
"Primitive Panel" over 30 years ago with a loss of gyros, then taking
away the Turn/Slip, the VSI, and leaving the student with little to
work with. They can do fine if they use their heads. Too many times in
over a thousand hours of actual IFR I've seen gyros fail as well as
other instruments and you had to extrapolate all the available
information. So far so good......

If I had to leave an instrument behind on takeoff, my choices would be:
1. VSI
2. DG
3. AI
4. TC
5. ASI
6. ALT

If I was going to have a single instrument fail during flight:
1. VSI
2. TC
3. DG
4. AI
5. ASI
6. ALT

During my IFR instruction my CFII allowed me to see the AI maybe one
out of ten hours. It actually felt weird when he let me see it. I could
take it or leave it for the most part until we get into unusual
attitudes. I'd like to think I could keep my grip long enough to figure
it out partial panel, but I know I can make sense of the situation a
lot faster with an AI.

A couple of years ago,a high-time pilot who, according to reports,
emphasized partial panel work, took off from TEB and soon killed
himself and family in a Bonanza. Apparently a gyro failure.

Have you any words of explanation to offer, or do you know what the
accident report said?

I practice partial panel regularly, but accidents like that worry me;
if that guy couldn't hack it, could I?
