Performance And The Pilot - Ch 1 Flashcards
Fatal Accidents on Take Off (%)
20% of all
Fatal accidents on Landing and Final Approach (%)
36% of all
Class A
10 or more seats
More than 5700kg
Includes all multiengine turbojets and turboprops
Class B
All piston props
Less than or equal to 5700kg
Less than or equal to 9 seats (Pax)
Class C
Large Piston prop
Less than or equal to 10 pax seats
Less than 5700kg
CS25
Covers larger better performing AC (certification specification)
CS23
Covers poorer performing AC normally small piston
Measured Performance
Brand new AC, test pilots flying, averaged results
Gross Performance
Measured performance degraded for average line pilots flying fleet AC using standard techniques
Net Performance
Worst case scenario, gross performance degraded by the application of a safety factor (closest to the danger)
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
Safety Factors
Required when probability of an event is greater than 1 in 1 million
Greater chance = greater safety factor
TO: 15%. Landing: 67%
TORA
T/O run available, threshold to threshold
Stopway
Overrun area at least the width of the RW
Clearway
Extra space, clear room in front of you
- 25% slope gradient
- No objects extend into clearway by >0.9m
- Min 75m either side of extended centre line
