16
Q

What is the relationship between VMCG and V1?

A

VMCG has to be equal to or less than V1

17
Q

What is min V2 with regard to Vs

A

Vs x 1.2

18
Q

What is the relationship between V2 and VMCA?

A

V2 is normally equal to or greater than 1.1 x VMCA

19
Q

What is V3 speed?

A

The all eng op takeoff climb speed that the aircraft will reach screen height

20
Q

What is V4 speed?

A

The all eng op speed that the ac will reach at 400ft

21
Q

How does humidity affect TO perf?

A

Increased humidity increases TODR. Humidity decreases air density.

22
Q

How much head/tail wind should be used for TO perf?

A

Not more than 50% of reported HW

Not less than 150% of reported TW

23
Q

What will runway downslope do to TODR?

A

ac will accelerate faster so TODR is reduced

24
Q

What is WAT?

A

Weight, altitude and temperature

25
Q

What do the WAT limits ensure?

A

That the ac’s MTOW is limited so that it meets second segment and missed app climb gradient perf with one eng inop

26
Q

What guaranteed alt/height would you be able to achieve at MTOW WAT limited conditions?

A

1500ft or circuit height.

27
Q

What is gross performance?

A

Average perf that a fleet of ac should achieve if flown using correct techniques
The ac should have a 50% chance of exceeding the gross perf

28
Q

What is net perf?

A

Gross perf adjusted for errors
