Flashcards in perf docs Deck (40):
1

vortex generator

high bypass ratio engine has a chine (vortex generator) to help airflow to flow smoothly over the wing

2

Ch 1 AOM limitations from 3 areas

1) Airplane Flight Manual (comply with airworthiness cert)
2) established by company for safety of operation
3) established by company in accordance with manufacturer recommendations

3

working limit envelope

allows for CoG movement in flight
fuel burn
flap movement and configuration changes

4

loading in shaded area

requires control of cargo lateral imbalance (may cause excessive load to main gear)

5

constant tail load

the strength of the tail and aft body structure can impose a limitation on the forward CoG limits

6

what limits Mmo

high speed limit by shock wave

7

what limits Vmo

high speed limit by air load

8

required takeoff field length

the longest of:
a) 115% takeoff dist AEO
b) takeoff dist OEI
c) ASD with OEI

9

B767 AFM takeoff perf only 1 type rwy

DRY

10

std for wet runway

v1 reduction
screen ht 15'
wt reduction for a few cases

11

std for slippery runway

more v1 reduction
v1 is limited by vmcg
wt reduction maybe required

12

perf of engine reduces greater than what temp

32 degs

13

obstacle limit

net flt path to have 35' over obst
net flt path is lower than actual flt path by 0.8%
on FPDM * indicates obst limit wt, not field limit wt

14

engine failure reference proc

provided for those airports where obstacles in the climbing course affect the safe clearance especially in IMC.

PIC takes all conditions into account, and takes the best way to clear the obstacles.

It may also be a good choice to enter the traffic pattern or avoid those obstacles visually in VMC condition

15

enroute limit

need to determine single engine ceiling and drift down

must clear obstacle by 2000' for D/D

16

landing limit

max allowable landing limit wt PLUS burn off fuel

17

zero fuel limit

max zero fuel weight PLUS on board fuel

18

tire speed limit and brake energy limit

only check brake energy limit as more restrictive

19

landing dist

for dry rwy
AFM = ANA
ACTUAL DIST/0.6

for slippery rwy
AFM (WET) = AFM (DRY) X 115%
ANA = CRITICAL OPERATION

20

CRITICAL OPERATION

ANA AFM wet

threshold spd Vref + 15 Vref
touchdown pt 2000' 950'
transition time 3 sec 0.3sec
braking force idle (max v slip) dry max force
reverse thrust as above not used
coefficient of length margin 1.0 complex

21

landing wt climb limit

no need to check unless under MEL or CDL

22

Cat I RVR <1200m, Cat II/III runway length

115% of DRY runway for weight. If landing wt less than WET (G) FPDM then this reqmt is met

23

does MAX THR always allow max wt?

shortens takeoff dist
improves climb gradient
lengthens the ASD at the wt that v1 is limited by vmcg

24

sel of THR for line ops

the lower the thrust the longer the engine life can be
reduced takeoff thrust is avail

25

abnormal landing conditions

threshold speed BUG + 5
touchdown speed ABOVE -4KTS
touchdown pt 1250'
transition time 3 SECS
deceleration during transition 2KTS/SEC
thrust BOTH REV 85% UNTIL 70KTS, OEI IDLE REV
brake MANUAL FULL BRAKE
braking coefficient DRY AFM, OTHERS AVG SLIPPERINES
temp DRY/WET 30 SNOW ETC 0
press alt SEA LEVEL

26

optimum alt

best fuel mileage for a given cruising airspeed and wt

27

buffet margin for cruise

1.3G for smooth or light turb
1.5G for moderate turb

28

optimum alt at 280000

FL 373

29

Balance arm (ARM) = datum pt

28.5 inches aft of airplane nose

30

MAC

237.5 inches
Leading edge of MAC = 913.2 inch in ARM

31

% MAC

to convert balance ARM to % MAC

%MAC = ARM -913.2
-----------------
2.375

32

what is OEW

ABEW plus standard operational items
ie crew, crew baggage, food and beverages

33

observer with baggage

+170lbs, and -1 Index U

34

child

3 to less than 12 (2 less than 12 international)

35

infant

less than 3 (less than 2 yrs international)
seated with adult is included part of adult wt
seated in own seat use std child wt

36

how many W + B forms?

B767 300 300ER DOMESTIC
B767 300 300ER INT SKED INT CHTR
B767 300F
B767 300F FERRY FLT AND CARGO <4000LBS
B767 300F WINGLETS

37

Aim of flt planning

with safety as a premise, the aim of flt planning is to maintain maximum ACL and economic operation with due consideration given to flight regularity

38

takeoff applied performance

1) deepest snow/slush of the 3 sections of rwy
2) the worst braking action of the last 2 section of the rwy used for takeoff

39

landing applied performance

1) choose worst braking action of the 3 rwy sections
2) if all 3 sections slush use slush perf

40

fuel flow for EAI and WAI

EAI 4lb/min
