Scheduled Performance 5 - Climb

Question 1

What is the Climb Gradient?

Answer 1

The vertical distance climbed divided by the horizontal distance covered and expressed as a percentage by multiplying the fraction by 100.

Question 2

What is the Phenom Climb Gradient at All Engines Operating (AEO)?

Answer 2

All Engines Operating (AEO) at maximum take-off weight is 18.2%

Question 3

What is the climb gradient of the phenom with one engine operating?

Answer 3

With One Engine Inoperative (OEI) the net climb gradient is only 3.8%.

Question 4

What are the factors affecting climb gradient?

Answer 4

Aircraft Take-Off Weight (TOW)
Aircraft Configuration
Thrust (TOGA with OEI)
Airspeed (V2 - VFS)
The pressure altitude at the airfield
The ambient temperature at the airfield
≤50% of the reported headwind component
≥150% of the reported tailwind component

Question 5

What is the affect of headwind on take-off?

Answer 5

A headwind will reduce the distance covered while climbing to a given altitude, which steepens the climb gradient and improves take-off climb obstacle clearance.

Question 6

What is the affect of a tailwind on take-off?

Answer 6

A tailwind increases the distance covered in the take-off climb, reducing the climb gradient, and reducing the obstacle clearance margins
