Extra Kollsman Altimeter Pointers

Mitty,

When I set the Kollsman window to 29.92 today, the main pointers show
about -200 feet (which is correct as the barometer now is actually
30.15). And as I mentioned, at a Kollsman setting of 29.92, these
extra pointers show 1,740 feet regardless of the actual barometric
pressure.

If these pointers are set to field pressure at your airport, then your
altimeter will read QFE. Your 30.15 was showing you QNH and set to
29.92, you read QNE.

If QFE is an unfamiliar term, it reads altitude above Field Elevation.
QNH is Nautical Height, and QNE is Nautical Elevation.
