4.3.4.2. Immediate Changes. When making a pitch adjustment on the attitude<br />

indicator to correct for an airspeed deviation, the airspeed indicator will not reflect an<br />

immediate change. The results of pitch attitude changes can often be determined<br />

more quickly by cross-checking the change in vertical velocity indication. For<br />

example, while climbing, a pilot notes that the airspeed is remaining slightly high and<br />

realizes that a small pitch adjustment is required. If the pitch adjustment results in a<br />

small increase of vertical velocity, the pilot knows, even though the airspeed may not<br />

yet show a change, that the pitch correction was approximately correct. When<br />

properly used in attitude instrument flying, the vertical velocity indicator is an<br />

excellent aid in maintaining airspeed.<br />

4.3.4.3. Desired Altitude. Prior to reaching desired altitude, determine a lead point<br />

on the altimeter. As a guide, use 10 percent of the vertical velocity. When the lead<br />

point is reached, smoothly adjust the power to an approximate setting required for<br />

level flight and simultaneously adjust the pitch attitude, if required to maintain the<br />

desired airspeed.<br />

4.3.4.4. Rate Climbs and Descents. Rate climbs and descents are accomplished by<br />

maintaining both a desired vertical velocity and airspeed. They are proficiency<br />

maneuvers designed to practice the techniques used during instrument approaches.<br />

Pitch attitude control is used to establish and maintain the desired airspeed. Power<br />

control is used to maintain the desired vertical velocity. Proper control techniques<br />

require coordinated pitch and power changes or adjustments.<br />

4.3.4.5. Normal Cruise Climb. To enter a climb from normal cruise, increase power<br />

to the setting that will produce the desired rate of climb (Figure 4.8). As power is<br />

increased, a correction for trim is made with pedals. If cruise and climb airspeeds are<br />

the same, there will be no apparent change of attitude, as read from the attitude<br />

indicator. If the amount of power applied does not produce the desired rate, make<br />

minor adjustments. During climb, the heading, attitude, and airspeed are maintained<br />

with cyclic control. Rate of climb is controlled with power and trim is maintained<br />

with pedals. Once established in a constant rate maneuver, deviations in desired<br />

VVI/airspeed must be properly interpreted. For example, VVI excursions can result<br />

because of incorrect power or inadvertent changes in pitch attitude (airspeed).<br />

Corrections are made on the control instruments with reference to the performance<br />

instruments.
