Two things here...1 use the weather radar as an AVOIDANCE tool, not a penetration tool; 2 If the airspeed indicator does not work or is giving erroneous information. Place the throttles in a known cruise position, usually jut forward of straight up, and put the nose in a cruise attitude, usually a few degrees nose high, and you might not be in perfect shape but the airplane is in relatively stable flight, i.e. it is not losing or gaining altitude or airspeed at a more than manageable rate.
Respect T’storms, they will kill you.

Sounds like you are describing an aircraft in proper trim. I am nobody's pilot, but I have heard that a properly trimmed aircraft will neither gain nor lose altitude in straight flight, so the pilot can take his hands off the yoke (and no autopilot, of course) and the plane will continue on in a straight, level path.

Do aircraft still use some modern version of the old Ryan Stormscope? Paul Ryan (not the Congressman) is one of our alums:
