Instrument Flying
Descending
Review
- Procedures to climb:
- Power + Attitude + Trim.
- 100 rpm = 5 kts = 100 feets per minute.
- Procedures to Level off:
- Power + Attitude + Trim.
Start leveling off at 10% of your rate of descent.
- Pitch control airspeed.
- Power control rate of descent.
Scan technique: descending
- What information do I need ?
- Pitch, speed, altitude, heading.
- Which instrument give me the needed?
- Attitude indicator and Airspeed indicator to ensure that the desired attitude is maintained. If the descent attitude is correct, the airspeed will stabilize at the desired airspeed. If the airspeed is low or high make an appropriate pitch correction
- Is the Information reliable ?
- Confirm the reliability of the heading indicator by referring to the turn coordinator and the magnetic compass.
- Confirm the reliability of the airspeed indicator by referring to the altimeter and the vertical speed indicator.
