Question 2

MEP.1.1.1 Complex Systems
MEP.1.1.1.1 Retractable Undercarriage

How is the undercarriage selected?

Answer 2

Electrically

Question 3

How is the normal extension and retraction?

Answer 3

Either:

• Direct by an electric motor, or
• Indirect by an electrically driven hydraulic pump

Answer 4

Vlo & Vle respectively

Question 5

What other maximum speeds may there be for selecting the undercarriage down and up?

Answer 5

One for selecting the undercarriage down, another for selecting the undercarriage up after take-off
