Appendix Flashcards
how are altimeter errors corrected? when do they apply and when do they not apply?
- errors are corrected for due to temperature using an altitude correction table. the correction factor is added to the reference altitude eg. DA, MDA etc.
- applies to any altitude on procedural inst. approach except VNAV approaches
- does not apply for assigned altitudes given by ATC
- ATC must be made aware of corrections
what happens to ASDn and ASDn-1 as V1 increases?
they both increase
What is ACN
- aircraft classification number
- it’s a measure of stress the aircraft wheels put on the tarmac. more wheels = more stress
What is PCN
- pavement classification number
- a value defining the strength of runways and taxiways
a PCN will have a number followed by 4 letters, what are the different combos of them
first letter: (F) flexible (R) rigid
second letter: (A) high (B) medium (C) low (D) ultra low
third letter: (X) pressure limit
fourth letter: (T) measured by technical evaluation (U) measured by usage
how do you know if your aircraft can land or use certain runways and taxiways using ACN and PCN
if ACN < PCN, its okay
if PCN < ACN, it’s not okay
found using the table (follow it down)
what is MAC
- mean aerodynamic chord
- the average chord length over the whole wingspan
how to convert CoG location as a % of MAC
CoG - (LE)MAC / MAC x 100 = % MAC
when should the decision to reject V1 be made
should be made by the captain before V1 so action can be taken AT V1.
What are the memory items for a high and low speed RTO
- close thrust levers
- speed brake
- brakes
- reverse thrust
What should be done for a low speed RTO
- below 80 knots
- memory items
- address failures
- communicate
- decision to taxi or go back
what should be done for a high speed RTO
- above 80 knots
- memory items
- address failures
- communicate w. fire service and ATC/cabin crew for evacuation
- stop on runway
- brake energy calcs if time permits
what are the effects of a continued takeoff 2 seconds before Vef w. engine failure
- reduced safety margins
- reduced climb gradients
- increased TOD, TODn-1
what happens following an engine fire
- Vef “fire bell”
- 400 feet, communicating and confirming failure
- memory actions
- shut down engine
- performance loss after 400 feet.
What happens following en engine failure
- Vef “bang” immediate loss of power
- 50% thrust
