    lower the nose slightly to increase airspeed.
  29. 3221. Excessively high engine temperature will ___
    cause loss of power, excessive oil consumption, and possible permanent internal engine damage.
  30. 3221-1. Excessively high engine temperatures, either in the air or on the ground, will ___
    cause loss of power, excessive oil consumption, and possible permanent internal engine damage.
  31. 3222. If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with ___
    too much power and with the mixture set too lean.
  32. 3241. Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges?
