Yes, symmetrical positioning of redundant sensors is common. 'Commonplace' and 'traditional' does not mean such positioning is not arbitrary.
Positioning sensors such that their relative ability to sense is dependent on common condition is not necessarily rational.
It merely makes them susceptible to failure when the ambient condition is unexpected
Why is it always ICE?
In the current condition, the symmetry is flawed....
Predicting (and making dependent) any multiple system on the 'expected' is
not sound.....
At the bottom of all this is the utter lack of a simple test for failure....
"Let's fail AoA, and see the response..."
"Let's fail Airspeeds, and assess autotrim..."
"Let's allow the ASI to drop to zero, and Test STALL WARN..."
"Let's put some knackered crew in the sim, and stuff the A/P...."
"Let's study manual handling in divergent Law/axis..."
What have I missed?
Oh... Isn't THS busy in this case, workin' ND ? Does the new AFM include, "Without Delay"?
