Perf Manual

Question 1

Section 2 : T/O

Fire and Rescue Categories for the variants
aka RFF….

Dept & Dest, All Alts except Etops, ETOPS

Answer 1

RFF Cats

788 - 8
789 - 9
78X - 9

DEPT/DEST - 1 below or 2 if tempo

T/O Alt, Dest Alt, ERA - 2 below or 3 if tempo (72 hrs max by NOTAM)

ETOPS enroute alts - 4 at 30 mins notice

Question 2

Section 2 : T/O

ICAO design code…

Answer 2

All are Code E (Wingspan < 65m)

Question 3

Section 2 : T/O Perf

Emergency Turn Procedures (ETP)
EGPWS Warning - how to fly

Answer 3

EGPWS CAUTION/WARNING can be expected after failure @ V1

Follow lateral ETP maintain SPD above V2
(Climb perf is based on this min speed)

Question 4

Section 2 : T/O

Temp Inversions

How do we identify them?

Answer 4

Forecast..
or CALM, CLEAR conditions at night, temp above ISA +15℃

Add 3℃ to reported temp prior to calc TOPL & Thrust reduction

Question 5

Section 3 : LANDING

Non normal - how to calc OPT figs
to ensure you can stop & make go around gradient

Answer 5

To ensure G/A climb gradient is achievable

• 2 engine Perf - NON FAILURE
• Flap 20 Engine out
• MEL / OVERWEIGHT

Calculates most limiting & distance increments

Question 6

Section 3 : LANDING

SOP - Minimum Reverse Idle
Except… 3 items

Answer 6

1. RWY - covered by standing water, snow, slush or ice.
2. Target Threshold Spd has been increased due to a deficiency.
3. Any unservicability of SPD BRKs, Brakes or Anti Skid

Question 7

Section 3 : LANDING

Brake Cooling, how long should you wait?

Answer 7

Wait 10 mins before check brake temps

Do not dispatch with BRAKE TEMP message

Question 8

Section 4 : T/O from CONTAMINATED Rwys

Where is the Flow Chart?

Answer 8

Perf 4.3

Question 9

Section 4 : T/O from CONTAMINATED Rwys

When is a runway contaminated?

Answer 9

When a significant portion, within the required length and width is covered by..

> 3mm water/wet snow/dry snow/slush, compacted snow or ice

for <3mm use WET data

Question 10

Section 4 : T/O from CONTAMINATED Rwys

What Limitations need to be observed 7 items…

Answer 10

• Snow + temp ABOVE -5℃ = SLUSH
• Refer to FCTM 3.14 for XWind guidelines
  (OPT will warn if Xwind is exceeded)
• FULL THRUST T/O
• Eng A/I on
• Use FULL LENGTH
• Min Runway & Cleared width 45m (150M)
• If not fully cleared consider it contamtd with whatever hasn’t been cleared
• TW > 5kts not recommended

Question 11

Section 4 : T/O from DEGRADED Rwys

Considerations, 4 items …

Answer 11

• FCTM for XWind guidelines
• FULL THRUST T/O
• No cleared width limits
• TW > 5kts not recommended

Question 12

Section 4 : Landing on CONTAMINATED or DEGRADED Rwys

Opt factor, min width, cleared width, what if it’s not fully cleared?

Answer 12

• Remember OPT includes a factor of 1.15%
• Min Width for Landing 45m
• Min CLEARED width 40m
• Consider it contaminated if not fully cleared.

Question 13

Section 5 : Driftdown and Depress

What if you can’t maintain MSA in event of IFSD?

Answer 13

Fuel Jettison

• Start dumping ASAP - brief before terrain

Question 14

Section 5 : Driftdown and Depress

How do we prepare for the Escape route…

Answer 14

Escape Route

• Prebrief and …
• MUST be loaded into route 2

Question 15

Section 5 : Driftdown and Depress

MSA Bandwidths are …

…might you go below FPlan MSA?

Answer 15

• Normal flight plan 10nm either side of trk
• RNP5 A/C MSA for Driftdown and depress can be reduced to 5nm
• A/C may descend below flight plan MSA as this is the highest between 2 waypoints
• Actual terrain clearance is calculated under the procedure (see procedures for actual MSA)

Question 16

Section 5 : Driftdown and Depress

Strong Wind adjustment…

Answer 16

Is not considered

Question 17

Section 5 : Driftdown and Depress

Turns - assumptions and the corridor..

Answer 17

• A/P engaged and bank angle selector set to AUTO
• A/C will exit the 10/5nm corridor but…
• Turn backs are completed early in the escape procedure at height.
