Question 1

vortex generator

Answer 1

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

Question 2

Ch 1 AOM limitations from 3 areas

Answer 2

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

Question 3

working limit envelope

Answer 3

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

Question 4

loading in shaded area

Answer 4

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

Question 5

constant tail load

Answer 5

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

Question 6

what limits Mmo

Answer 6

high speed limit by shock wave

Question 7

what limits Vmo

Answer 7

high speed limit by air load

Question 8

required takeoff field length

Answer 8

the longest of:

a) 115% takeoff dist AEO
b) takeoff dist OEI
c) ASD with OEI

Question 9

B767 AFM takeoff perf only 1 type rwy

Answer 9

DRY

Question 10

std for wet runway

Answer 10

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

Question 11

std for slippery runway

Answer 11

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

Question 12

perf of engine reduces greater than what temp

Answer 12

32 degs

Question 13

obstacle limit

Answer 13

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

Question 14

engine failure reference proc

Answer 14

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

Question 15

enroute limit

Answer 15

need to determine single engine ceiling and drift down

must clear obstacle by 2000’ for D/D

Question 16

landing limit

Answer 16

max allowable landing limit wt PLUS burn off fuel

Question 17

zero fuel limit

Answer 17

max zero fuel weight PLUS on board fuel

Question 18

tire speed limit and brake energy limit

Answer 18

only check brake energy limit as more restrictive

Question 19

landing dist

Answer 19

for dry rwy
AFM = ANA
ACTUAL DIST/0.6

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

Question 20

CRITICAL OPERATION

Answer 20

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

Question 21

landing wt climb limit

Answer 21

no need to check unless under MEL or CDL

Question 22

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

Answer 22

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

Question 23

does MAX THR always allow max wt?

Answer 23

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

Question 24

sel of THR for line ops

Answer 24

the lower the thrust the longer the engine life can be

reduced takeoff thrust is avail

Question 25

abnormal landing conditions

Answer 25

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

Question 26

optimum alt

Answer 26

best fuel mileage for a given cruising airspeed and wt

Question 27

buffet margin for cruise

Answer 27

1. 3G for smooth or light turb

1. 5G for moderate turb

Question 28

optimum alt at 280000

Answer 28

FL 373

Question 29

Balance arm (ARM) = datum pt

Answer 29

28.5 inches aft of airplane nose

Question 30

MAC

Answer 30

237.5 inches

Leading edge of MAC = 913.2 inch in ARM

Question 31

% MAC

Answer 31

to convert balance ARM to % MAC

%MAC = ARM -913.2

           - ----------------
              2. 375
