re# 826 and others and climb rates
..." "This rate of climb is very high, too high. It appears to be beyond the performance envelope of the aircraft”
Wouldn't the local change in baro pressure in a major updraft or downdraft give false readings to the transponder instrumention- thus indicating a major change in altitude even in relatively level flight- thus the computer(s) have a garbage in- garbage out issue ?
Or were the so called "radar" readings based on actual target -skin return changes? ( I'm doubtful of skin returns at that distance from radar )
Seems to me would have to wait for combination of readings/g levels from FDR ?
