Nose Low v. Nose High

1. Failure to keep the airplane properly trimmed. A cockpit

interruption when you are holding pressures can easily lead to inadvertent entry into unusual attitudes.

1. Disorganized cockpit. Hunting for charts, logs, computers,

etc., can seriously detract your attention from the instruments.

1. Slow cross-check and fixations. Your impulse is to stop

and stare when you note an instrument discrepancy unless you have trained enough to develop the skill required for immediate recognition.

This maneuver is a series of climbs and descents at a definite indicated rate.

1. Climbing or descending airspeed should be established prior to entry.
2. During the reversal of vertical direction, lead the altitude 40 to 60 feet in descents and 20 to 30 feet in climbs.
3. Change the altitude 500 feet, 400 feet, 300 feet, then 200 feet, returning to the original altitude each time. After the 200-foot altitude change, return to the original altitude and level-off at climbing or descending airspeed (low cruise).
4. Performing the Vertical S.
   1. From an exact altitude and climbing or descending airspeed, adjust power and pitch attitude to enter a climb or descent.
   2. As the power is adjusted in the entry, the airspeed indicator becomes primary for pitch.
   3. As the vertical speed approaches 500 feet per minute, the vertical-speed indicator becomes primary for pitch and remains so until the reversal of the vertical direction is started. As the vertical speed reaches 500 feet per minute, the airspeed indicator again becomes the primary instrument for power.
   4. As the reversal of the vertical direction is started, the airspeed indicator becomes primary for pitch and remains so until the vertical speed approaches the desired rate of 500 feet per minute.
   5. Stress the importance of trim and cross-check.
