Brady ROT

Question 1

ROT: Level flight deceleration

Answer 1

Allow 10 kts per nm
Allow 1 kt per second
*Deceleration is faster at lower weights

Question 2

ROT: Descending flight deceleration

Answer 2

Allow 5 kts per nm

Allow 0.5 kts per second

Question 3

ROT: Distance covered during IDLE descent

Answer 3

Allow 3 nm per 1000 feet

Question 4

ROT: Approach profile planning

Answer 4

Aim for 250 kts at 10,000 ft by 30 nm out

Aim for 210 kts on ILS at 12 nm

Question 5

ROT: What speed, distance should you plan to arrive on the ILS?

Answer 5

Aim for 210 kts on ILS at 12 nm

Question 6

ROT: Cruise N1 (& resultant fuel flow)

Answer 6

N1 = (2 x alt / 1000) + 10
ex: at FL350: 35000 x 2 = 70000 / 1000 = 70 + 10 = 80% N1

FF = (IAS x 10) / 2 - 200
ex: at 250 kts: 250 x 10 = 2500 / 2 = 1250 - 200 = 1050 kg / hr / engine

Question 7

ROT: 737-800 attitude & N1

Clean speed

Answer 7

6 deg nose up

58% N1

Question 8

ROT: 737-800 attitude & N1

Flap 1, 190 kts

Answer 8

6 deg nose up

61% N1

Question 9

ROT: 737-800 attitude & N1

Flap 5, 180 kts

Answer 9

6 deg nose up

63% N1

Question 10

ROT: 737-800 attitude & N1

Gear down, Flap 15, 150 kts

Answer 10

6 deg nose up

71% N1

Question 11

ROT: 737-800 attitude & N1

Question 12

ROT: 737-800 attitude & N1
On glideslope
Gear down, Flap 30, Vref +5

Answer 12

1 deg nose up

58% N1

Question 13

ROT: 737-800 attitude & N1
On glideslope
Gear down, Flap 40, Vref +5

Answer 13

0 deg nose up

64% N1

Question 14

ROT: Progression of attitude and N1 for a 737-800 on glideslope?

Answer 14

Flap 15, 150 kts: 2 deg, 53%
Flap 30, Vref+5: 1 deg, 58%
Flap 40, Vref+5: 0 deg, 64%

Question 15

ROT: Progression of attitude and N1 for a 737-800 in level flight while progressively lowering flaps

Answer 15

Clean speed: 6 deg, 58%
Flap 1, 190 kts: 6 deg, 61%
Flap 5, 180 kts: 6 deg, 63%
Flap 15, 150 kts, gear down: 6 deg, 71%
