Limted PWR Ops

Question 1

Explain what approaches/departures are flown at each perf cat:

Answer 1

Cat 0 = IGE AP/Rolling T/O
Cat 1 = IGE AP/DEP
Cat 2 = Profile AP/DEP
Cat 3 = Profile AP/Marginal OGE DEP
Cat 4 = Profile AP/OGE departure

Question 2

Explain the sequence for an IGE approach:

Answer 2

50kts commence a shallow angle flat ATT RLDG —> Once committed maintain ETL until HIGE —> 5ºNU decel maintain 10ft AGL

Question 3

Explain the sequence for a profile approach into a CA:

Answer 3

60kts —> normal to shallow angle —> maintain above F1 —> committed —> rate of closure scan —> look at PWR margin —> Terminate IGE

Question 4

Explain the sequence for an OGE approach:

Answer 4

50kts —> normal to steep angle —> maintain flyaway heights until @ designated HHP —> committed —> vertical descent

Question 5

Explain the sequence for a rolling T/O:

Answer 5

Rolling T/O 200m for 10kts F1 —> COL until light on wheels —> Cyclic edge of box —> @23/25KTS GS increase COL to TOP —> 1ºNU after liftoff (Consider decision point)

Question 6

Explain the sequence for an IGE departure:

Answer 6

Achieve ETL while in ground effect —-> taxi through ETL —> @ ETL assess excessive PWR, then pull to MCP to climb away

Question 7

Explain the sequence for a profile departure:

Answer 7

Assess DEP angle —> pick a decision point —> 5ºND/MCP —> Assess IAS/angle —> Flyaway or abort

Question 8

Explain the sequence for a marginal OGE departure:

Answer 8

MCP —> Vertical climb —> Passing HHP —> 15ºND/MCP —> Flyaway @ F speed

Question 9

Explain the sequence for an OGE departure:

Answer 9

Vertical climb —> Passing HHP —> Nose forwards IOT achieve F speed

Question 10

How is ground roll distance calculated for the rolling T/O?

Answer 10

For every 10kts of F speed, ground roll = 200m. Then double that for the abort distance and add a buffer, x2.5

E.g. 40kts F speed = 4 x 200 = 800m. 800 x 2.5 = 2000m RWY required

Question 11

How is ground roll calculated for an IGE approach?

Answer 11

30m ground roll for every 10kts G/S

Question 12

Why is the CAT 3 OGE departure allowed but approach banned?

Answer 12

The approach is banned because if you had too high RoD coming down, you don’t have the power margin to correct

Question 13

Above 6100kgs, what restrictions are applied to manoeuvring?

Answer 13

No greater than 30ºAoB, rate 1 turns where possible and gentle roll inputs
Slope landing: 8L, 8NU, 3ND

Question 14

What considerations are there when selecting the decision point in the CAT 2, profile departure?

Answer 14

• Shallowest departure angle into wind
• Downhill departure
• 10ft obstacle clearance
• Escape route (If OEI exactly at F1 and unable to climb)

Question 15

How can pilots determine if the departure angle for a CAT 2 approach is too steep?

Answer 15

The 10ft obstacle clearance point must be below half way up the windscreen, if above, then too steep

Question 16

What time limits are there for operating above MCP when AEO?

Answer 16

TRANSIENT class B if MCP for 5 sec, you can still operate for another 10 secs without and damage/post flight

Question 17

What additional aircraft limits are associated with operation between 6100 and 6400kgs? (5)

Answer 17

Below 120KIAS: Not above 60ºAoB/2Gs
Above 120KIAS: Not above 55ºAoB/2Gs
VNE: 160KIAS
Max Yaw Rate: 30º/sec
Max sideways hover: 20kts

Question 18

What is the max speed with the tail wheel locked during a rolling takeoff?

Answer 18

35kts G/S
