Limted PWR Ops Flashcards
Explain what approaches/departures are flown at each perf cat:
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
Explain the sequence for an IGE approach:
50kts commence a shallow angle flat ATT RLDG —> Once committed maintain ETL until HIGE —> 5ºNU decel maintain 10ft AGL
Explain the sequence for a profile approach into a CA:
60kts —> normal to shallow angle —> maintain above F1 —> committed —> rate of closure scan —> look at PWR margin —> Terminate IGE
Explain the sequence for an OGE approach:
50kts —> normal to steep angle —> maintain flyaway heights until @ designated HHP —> committed —> vertical descent
Explain the sequence for a rolling T/O:
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)
Explain the sequence for an IGE departure:
Achieve ETL while in ground effect —-> taxi through ETL —> @ ETL assess excessive PWR, then pull to MCP to climb away
Explain the sequence for a profile departure:
Assess DEP angle —> pick a decision point —> 5ºND/MCP —> Assess IAS/angle —> Flyaway or abort
Explain the sequence for a marginal OGE departure:
MCP —> Vertical climb —> Passing HHP —> 15ºND/MCP —> Flyaway @ F speed
Explain the sequence for an OGE departure:
Vertical climb —> Passing HHP —> Nose forwards IOT achieve F speed
How is ground roll distance calculated for the rolling T/O?
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
How is ground roll calculated for an IGE approach?
30m ground roll for every 10kts G/S
Why is the CAT 3 OGE departure allowed but approach banned?
The approach is banned because if you had too high RoD coming down, you don’t have the power margin to correct
Above 6100kgs, what restrictions are applied to manoeuvring?
No greater than 30ºAoB, rate 1 turns where possible and gentle roll inputs
Slope landing: 8L, 8NU, 3ND
What considerations are there when selecting the decision point in the CAT 2, profile departure?
- Shallowest departure angle into wind
- Downhill departure
- 10ft obstacle clearance
- Escape route (If OEI exactly at F1 and unable to climb)
How can pilots determine if the departure angle for a CAT 2 approach is too steep?
The 10ft obstacle clearance point must be below half way up the windscreen, if above, then too steep
What time limits are there for operating above MCP when AEO?
TRANSIENT class B if MCP for 5 sec, you can still operate for another 10 secs without and damage/post flight
What additional aircraft limits are associated with operation between 6100 and 6400kgs? (5)
Below 120KIAS: Not above 60ºAoB/2Gs
Above 120KIAS: Not above 55ºAoB/2Gs
VNE: 160KIAS
Max Yaw Rate: 30º/sec
Max sideways hover: 20kts
What is the max speed with the tail wheel locked during a rolling takeoff?
35kts G/S
