Performance

Question 1

TODR

TORR

Answer 1

1800 ft clear 50ft

1100 ft

Question 2

Torr

Answer 2

TORR = TODR

Question 3

Up slope of 2%
(TO)

Downslope
2%
(Lnd)

Wet

Answer 3

Increase 10%

Increase 10%

LDR only Increase 15%

Over 3% add 5% for each. Percentage for slopes

Question 4

ROC

Answer 4

1100 fpm

Question 5

OIE climb rate

Answer 5

100-150 FPM

Question 6

LDR
LRR

Safe landing

Answer 6

1900ft
1100 ft

Safe landing

LRR = LDR

Question 7

Cruise 55%

Approx fuel consumption per eng

Answer 7

4 gallons per hour
16 litres

Per engine

3-4 hours flight time

Question 8

MTOW

MLM

Answer 8

1785kg
1700kg

85/3 = 25 us gallons

Question 9

TORR T departure

Rwy 26
Rwy 08

Answer 9

2500ft

2100ft

Question 10

ASDR =

Answer 10

ASDR = TORR + LRR + 80m

Question 11

Legal Dispatch to destination airfield

Answer 11

Must be able:

A) land the most favourable rwy in still air conditions
B)the most likely in the forecast met

Question 12

LDR

Answer 12

LDR x 1.43 must not exceed LDA

Question 13

TODR

Answer 13

TODR x 1.25 must not exceed TORA

Question 14

Destination Alternative

Answer 14

One if both:
Planned duration less than 6 hours
2 separate rwys 1 hour before+after ETA is 5km vis 2000ft cloud base or circling Minima + 200ft

Question 15

Planning minima if looking forward a non precision app

Answer 15

Non precision
Min + 200ft
RVR + 1000m

Question 16

Converting to RVR?

Answer 16

Take Met via and multiple by factor in jeppesoon according to the lighting system available

Alternatively take the RVR minima or CMV and divide by factor to find minima

Question 17

Head tail factors

Answer 17

50% hdg

150% tailwind

Question 18

What is pressure alt + density alt?

Answer 18

Example

Elevation 38ft
10 degrees

QNH - 1013 - 993hpa = +600ft would read on the altimeter without change on the rwy because the pressure = 638ft

8-15 = - 7 degrees difference
7 degrees colder X 120ft = 840ft lower

Density alt = 638ft - 840ft = -200
The aircraft will perform better

Question 19

When should you not fly when calculating climb performance?

Answer 19

150ft/m OEI

Question 20

NG

MTOW
MLM

Answer 20

1999kg

1999kg

Question 21

When can TORA be less than 1.25 x TORR

Answer 21

When TODR x 1 less then TORA
TODR x 1.15 less than TODA
TODR x1.3 less than ASDA

In other words if there is a stop way or clearway

Question 22

Max drift normal Asym

Answer 22

120kts - divide by 2

Asym 105kts - wind speed x 0.6
Slightly greater max drift affects

Question 23

Take off alternative

Answer 23

Required if you can’t land back on departure aerodrome for Met reasons

2 engine ac must be within 1hr flight time on single engine speed

Weather +- 1hr eta must be at or better than landing minima

If the only app available are non precison felling is considered

Question 24

Destination alternative

One required unless

Answer 24

Planned duration is less than 6 hrs 
2 separate rwy available 
Weather +- 1 he eta is:
5 km 
2000ft cloud base
Or circling minima plus 500ft

Question 25

Destination alternative | 2 required if

Answer 25

Weather is forecast below planning minima No Met I formation is available

Question 26

Planning minima for destination alternative

Answer 26

Use the minima for the next type of app Cat 1 use non precision app minima (RVR + ceiling above MDA)
