Chapter 1 - General Theory Flashcards
Where are the rules EASA rules set out for performance certification and for which a/c types?
CS23 - smaller aircraft
CS25 - large aircraft
What is Measured performance
Achieved by test pilots on test/new aircraft
What is Gross performance
The average aircraft performance which a pilot can expect to achieve on a normal day
What is Net performance
Gross performance reduced to ensure a margin of safety
What is the acceptable level of safety chance
If under the value what has to be done
1 in a million
If the probability is greater than above - the larger the safety factor is required
Class A (CS25) =
Give Perf and Op’s rules
All multi-engine jets and turbo props;
carry 10 or more pax
OR
greater than TOM 5700 KG
Perf rules - strict
Op’s rule - relaxed
Class B (CS23) =
Give Perf and Op’s rules
All pro driven a/c;
9 or less pax
OR
TOM 5700 KG or less
Perf rules - relaxed
Op’s rule - strict
Class C =
Large multi-powered piston a/c;
10 or more pax
TOM greater than 5700 KG
What happens to Net (application of safety factor) climb gradients compared to Gross
Reduce
When do Net performance figures increase? x3 Situation
Take Off distance
Decent gradients
Landing Distance
What is the Clear Way
Is an area after the TORA which is free of any obstacles
Min width 500 feet
No more than 50% of the TORA
What is the Stop Way
An area at the end of the TORA which can be used for emergency stops
Must be at least the width of the runway
What does ASDA =
TORA + Stopway
What does TODA =
TORA + Clearway
If you have an overload of 10% PCN what are the sitpulation
Pavement older than 10%
No visible signs of damage
Overload operation are no greater than 5% of the annual movements
