Setting altimeters with no radio

For VFR, an adjustable altimeter is not required. Therefore, such a 100
mile rule doesn't exist.


What aircraft altimeter is not adjustable? IFR flight requires a sensitive
altimeter adjustable for barometric pressure, VFR flight simply requires an
altimeter. But even altimeters that cannot be adjusted for barometric
pressure are adjustable. My Champ' came with a single-needle altimeter,
once around the dial was 10,000 feet. I hated it, the needle never seemed
to move. But there was an adjustment knob that rotated the dial so the
needle would point to field elevation.

The regulation requires aircraft without radios to set the altimeter to the
elevation of the departure airport or an appropriate altimeter setting
available before departure.
