Straight Climbs and Climbing Turns
| Objective: |
To familiarize the student with the procedures and aerodynamics involved in climbs and climbing turns. |
| Content: |
Before Flight:
- Ability to climb limited by thrust available
- What power/pitch settings lead to following climbs:
- Normal climb
- Better engine cooling
- Easier control
- Better visibility over the nose
- Best rate of climb, Vy
- Airspeed at which most excess power is available
- Best angle of climb, Vx
- Airspeed at which most excess thrust is available
- As altitude increases, Vx increases and Vy decreases. The point at which they meet is the absolute ceiling of the airplane
- Higher angle of attack and slower airspeed will cause torque and asymmetrical propeller loading to cause airplane to roll and yaw left
- Initiate level-off at 10% of climb rate above/below desired altitude
- Loss of vertical lift due to turning
- Adverse yaw more pronounced in climbing turns because of lower speed
During Flight:
- Student should add power and pitch up simultaneously for a straight climbing
- Student should adjust aircraft attitude in relation to outside references, only checking his accuracy using aircraft instruments
- Student should begin to level off at about 10% of the climb rate above/below desired altitude
- After leveling off, student should maintain climb power until cruise speed is reached
See AFH C. 3-13 to 3-15 |
| Completion Standards: |
The lesson is complete when the student is able to perform straight climbs and climbing turns to the satisfaction of the instructor and in accordance with the current Practical Test Standards for the student’s stage of training. |
