Stupid transponder question, or, stumped by the wife

In most Cessnas with electric horns, the CB is a hidden "auto-reset"
device that you can't pull. The master doesn't count.


Does the lift detector count?

no electronic horn.. no way to turn it off.. as in the light weight
cessnas..

Then why doesn't the stall warning horn have one?

The stall warning horn in all of my aircraft have two: The CB and the
one labeled "master".

John,

I honestly never thought about it and couldn't answer her question. Does
anyone know?


Heard twice within the last two months on ATC:

N12345, your transponder is indicating FL240, say altitude.
N12345, altitude 3000 feet
N12345, in that case, please turn off your transponder and have it
repaired

or words to that effect.

Irrelavant. The radar computer has software that will not show any
target within the user specified distance from the radar antenna. We
set ours to 1 mile. There are also altitude filters that can be set.
There is no good reason to ever turn your transponder off or to STBY
unless ATC asks you to or you somehow know it's not working properly.

There's still another problem called FRUIT (False Replies Unsynchronised
in Time). The radar bean has a width of about 3 degrees. All the
transponders in this small area respond with their code as soon as the
radar beam hits them. A major installation can handle up to ten codes
simultaneously. But if on a nice Sunday several hundred VFR air planes
are about the situation has arisen where the targets could no longer be
properly separated, with the result that the important echoes of
commercial traffic disappeared in the maze.

The controller can erase the VFR echoes, but when the radar con not read
them anymore the legibility of the remaining echoes is not improved.
Actually, this is one of the reasons why mode S is introduced.

The words should have been "stop altitude squawk."

I am surprised that ATC would have the pilot turn off the transponder. Why
wouldn't they simply ask to stop squawking altitude (switch to Mode A)?
