Class B Regs

Question 1

SEP requirements

Answer 1

Most restrictive ops requirements
Not allowed to do it at night/instrument flying
If a MEP does not meet standard, it should be flown as a SEP

Question 2

MEP climb gradient regs, all engine

Answer 2

Design requirement - with all engines - must achieve a climb gradient of a min 4% with max power
If the gear can get up in 7 secs - dont have to inc it in calcs

Question 3

Climb regs 1 engine inop at 400ft MEP

Answer 3

400 ft - must be able to achieve a positive climb gradient - can be zero
With t/o flaps
Based on V2 speed/ whatever is reached at 50ft

Question 4

1500ft 1 engine inop regs MEP

Answer 4

1500ft - must be able to achieve a gradient of 0.75
Based on critical engine failure
Based on MCT
Flaps retracted
Speed of no less 1.2x stall speed in clean config vs

Question 5

TOD factors MEP

Answer 5

TOD <= TORA
TOD x 1.15 <= TODA
TOD x 1.3 <= ASDA

Whichever is the smallest = TOD allowed

(TOD x 1.25 <= TORA)

Question 6

Upslope factor MEP

Answer 6

Every 1% of up slope you factor 5% of TOD

Question 7

Grass safety factors MEP

Answer 7

Up to 20cm = increase TOD by 1.2

Wet grass = 1.3

Question 8

For an airfield to be judged as contaminated

Answer 8

Min 25% contaminated and up to 3mm in depth

Question 9

SEP obstacle clearance

Answer 9

There isn’t any as you wont be flying in IMC

Question 10

Min height to clear an obstacle

Answer 10

50ft

Question 11

To find the lateral distance we have to fly to avoid an object MEP

Answer 11

60m + 1/2 wingspan (max 90m)

And then 0.125 x d in m

Question 12

After t/o turning regs MEP

Answer 12

Can’t make a turn until 50ft/half a wingspan - not allowed to turn more than 15*

Question 13

Climb gradient up to 1500ft MEP

Answer 13

We use 0.77 of the all engine gradient for calcs - up to the cloud base

Question 14

Cloud base safety factor MEP

Answer 14

Assume 1 engine climb gradient when you hit the cloud base

Question 15

En route regs starts and ends MEP

Answer 15

1,500ft from the departure Airfield and ends 1,000ft above the arrival Airfield

Question 16

Glide distance is based on MEP

Answer 16

Where we glide from to 1,000ft

Question 17

Gradient enroute MEP

Answer 17

Would have to degraded by 4% to make sure clear obstacles

Question 18

Assumed max height class B

Answer 18

Where the max roc achieved is 300fpm

Question 19

Class b - any gradient enroute would have to

Answer 19

Be degraded by 4% to make sure we clear obstacles

Question 20

L/d - class B

Answer 20

Barrier height

Prop are allowed to use 70% of the LDA

Stopway is not included in the l/d distance

Question 21

Baulked l/d - class B

Answer 21

Rejected t/o when already committed

Have to achieve a min 2.4% climb gradient with gear down and flaps in l/d pos

MEP - have to consider an engine failure

Question 22

Missed approach - class B

Answer 22

At 1500ft you need to achieve a 0.75% climb gradient min with flaps in the l/d config and the gear up
