Performance Class A Theory

Question 1

Drift down procedure

Answer 1

Airplane descents lower when engine fails for denser air to generate more thrust to equal the drag.

Continued to the net level off altitude

Question 2

De rated thrust take off

Carried out on both dry and wet runways
Full or TOGA thrust cannot be selected
Lower values of Vmcg and Vmca
Allow a higher limiting TOM

Less thrust = less yaw force = reduced Vmcg

Question 27

Calculating TOD on dry runway - Field Length Requirements specified in CS25

Answer 27

TODN x 1.15 TODN -1 (no safety factor applied to one engine) Brakes release to midway between VLOF and screen height

Question 28

Calculating V1 wet

Answer 28

Find the greatest of TODN-1 wet - (no safety factor) TODN DRY - 1.15 safety factor TODN1 dry (no safety factor) Greater of the above

Question 29

Landing on a flooded runway in stormy conditions

Answer 29

Increase approach speed - prevent stall from increased drag from rain Land firmly to obtain firm contact of wheel with runway Use all lift dumper devices Apply brakes up to anti skid activation

Question 30

De rated vs flex thrust

Answer 30

De rated - allows for operation on all runways Reduced thrust - not allowed on contaminated runways/anti skid inop/Windshear

Question 31

CLTOM is increased when

Answer 31

Lower flap setting =higher gives more drag reducing excess thrust therefore lower increases climb limited take off mass Higher air density = lower altitude more dense therefore more thrust giving a higher CLTOM Lower outside air temperature = increased density improving gradient

Lift off may be too slow and insufficient above VMCA and VMU for safe flight Aeroplane climb shallower than planned angle Risk of tail strike Reduce margin above VMCA and VSR Aircraft may not lift off
