Flashcards in Performance And The Pilot - Ch 1 Deck (20):
1

Fatal Accidents on Take Off (%)

20% of all

2

Fatal accidents on Landing and Final Approach (%)

36% of all

3

Class A

10 or more seats
More than 5700kg
Includes all multiengine turbojets and turboprops

4

Class B

All piston props
Less than or equal to 5700kg
Less than or equal to 9 seats (Pax)

5

Class C

Large Piston prop
Less than or equal to 10 pax seats
Less than 5700kg

6

CS25

Covers larger better performing AC (certification specification)

7

CS23

Covers poorer performing AC normally small piston

8

Measured Performance

Brand new AC, test pilots flying, averaged results

9

Gross Performance

Measured performance degraded for average line pilots flying fleet AC using standard techniques

10

Net Performance

Worst case scenario, gross performance degraded by the application of a safety factor (closest to the danger)

11

Safety Factors

Frequent: 1/1000
Reasonably Frequent: 1/1000 to 1/100000
Remote: 1/100000 to 1/10000000
Exceptionally Remote: 1/10000000 to 1/1000000000

12

Safety Factors

Required when probability of an event is greater than 1 in 1 million

Greater chance = greater safety factor

TO: 15%. Landing: 67%

13

TORA

T/O run available, threshold to threshold

14

Stopway

Overrun area at least the width of the RW

15

Clearway

Extra space, clear room in front of you
1.25% slope gradient
- No objects extend into clearway by >0.9m
- Min 75m either side of extended centre line

16

ASDA

Accelerated stop distance available (EMDA)

TORA + Stopway

For rejected TOs

17

TODA

TORA + Clearway
Up to the first significant obstacle
MAX 1.5 x TORA

18

Balanced Field

When ASDA = TODA

If unbalanced, use the shortest distance

19

PCN

Pavement classification number

Can be exceeded occasionally, down to Airfield operators
Flexible 10%
Rigid 5%

20

ACN

Aircraft Specification Number
