  1. Airspeed indicator
  2. Altimeter ✔
  3. Vertical speed indicator

Why: In level flight, a pitch error shows up as an altitude change, so the altimeter is the primary pitch instrument. The attitude indicator, VSI and airspeed indicator support it.

Huh, didn't know that: The airspeed indicator gives only an indirect indication of pitch attitude.
