Think in terms of the cost of the altimeter as a percentage of the total cost of the aircraft, then thing of all the ways you can get into trouble with a miss-reading altimeter.

So half of a percent of the aircraft value (even 5% for that matter) is not that significant.

"NonTSO" has no more meaning for an altimeter than if they said "contains no additives nor preservatives." If a mfr does not produce a TSO'd version, it could be oriental junk. If they do (and who does?), to produce a TSO and a nonTSO'd version of an altimeter costs the same, if it's of the same design. If you're paying substantially less, how can you be sure of what you're getting? Reg, Fred F.
