13. Aircraft Operations - Types & Categories Flashcards
What are the ICAO Wake Turbulence Categories
SUPER (J) - A380-800 Recommended by ICAO
HEAVY (H) - 136 000 kg or greater
MEDIUM (M) - >7,000 kg but <136,000 kg
LIGHT (L) - <7,000 kg
What is Wake Turbulence?
Turbulent Wake (see Induced Drag/Wing Tip Vortices) is produced by most aircraft, especially when flying slowly, is ‘clean’ and at high angles of attack
e.g. departure and on ‘Final Approach’.
What is Approach speed based on?
Based on 1.3 times stall speed in the landing configuration at maximum certificated landing mass.
Approach Categories
Cat. A: less than 91 kts IAS
Cat. B: 91/120 kts IAS
Cat. C: 121/140 kts IAS
Cat. D: 141/165 kts IAS
Cat. E: 166/210 kts IA
What are the noise categories based on?
Based upon decibels - EPNdB (Effective Perceived
Noise in Decibels
What is CDA?
Continuous Descent Approach
Descents from an optimal position with minimum thrust and avoids level flight to the extent permitted by the safe operation of Aircraft
What is the principle of CDA?
The principle is that CDA can be implemented from any altitude but, where and when possible, the aim should be an optimised descent profile from Top of Descent. (ToD)
