Straight, Constant Airspeed Climbs / Descents (Instrument)
Written by Jack on May 31st, 2008
| Objective: |
To enhance the student skills and comfort with performing straight, constant airspeed climbs and descents under instrument meteorological conditions. |
| Content: |
Before Flight:
- Climbs:
- Under given power setting and load condition, only one attitude will give most efficient climbs
- Entry:
- From cruising airspeed, raise mini aircraft to approximate nose-high indication for predetermined climb speed
- Power may be set to climb power simultaneously, or after pitch change
- See IFH Figure 5-25 for Primary and Supporting Instruments
- Stabilized Climb at Constant Airspeed:
- See IFH Figure 5-26 for primary and supporting instruments
- Leveling Off:
- Level off before reaching desired altitude (lead by 10% VS)
- To level off at climb airspeed, reduce power simultaneously with pitch change
- See IFH Figure 5-29 for primary and supporting instruments
- Descents:
- Entry:
- Reduce power first to descent speed and then pitch to maintain that speed
- Any airspeed deviation calls for pitch adjustment
- See IFH Figure 5-30 for primary and supporting instruments
- Leveling Off:
- Apprx. 100-150 feet above altitude, set cruise power (for level flight at higher than descent speed)
- Begin to level-off 50 feet above altitude
- To level-off at descent airspeed, level-off and set cruise power at 50 feet above altitude
- See IFH Figures 5-31 and 5-32 for primary and supporting instruments

During Flight:
- Instructor ensures student follows procedures outlined before flight
See Instrument Flying Handbook C. 5-16 to 5-22 |
| Completion Standards: |
The lesson is complete when the student demonstrates knowledge through a written or oral exam and is able to perform straight, constant airspeed climbs and descents with reference to the instruments to the satisfaction of the instructor and in accordance with the current Practical Test Standards for the student’s stage of training. |
