Question 1

TODR X …. < ? (No stopway or Clearway)

Answer 1

TODR X 1.25 < TORA

Question 2

TODR X …… < …….. (stopway and/or clearway)

Answer 2

TODR < TORA
TODR X 1.15 < TODA
TODR X 1.3 < ASDA

Question 3

What height must you ensure you clear obstacles by on takeoff

Answer 3

50ft

Question 4

Equation to calculate horizontal obstacle clearance (wingspan less than 60m)

Answer 4

1/2 aircraft wingspan + 60m + 0.125D

D = distance travelled from T/O to obstacle
