Flashcards in Landing - Ch 13 Deck (14):
1

Starts

Screen height 50ft

2

Stops

Full stop

3

Landing distance

The difference between the screen heigh and the full stop (LD)

4

LDR

Landing distance required

5

Distance of landing effected by

Speed and weight

5% faster = 10% longer LD

6

Vref

Min: VMCL
Above stall SPD: Class B: 1.30VS0 Class A: 1.23Vsr0

7

Stop Distance Determined by

Brakes
Reverse Thrust
Drag

Reverse thrust used more than brakes when RW contaminated

8

Contamination effect on LD

You must be below Vp before you start braking/before they start taking effect

Positive touchdown

9

Brakes and Temperature

Higher temp can decrease the effectiveness/efficiency of the brakes

Brakes heat up as you use them

10

Vref affected by

Vref increases with decreasing flap setting

Decreased air density will increase Vref (hot and high)

As they increase you GS

11

Wind

Headwind: Decreases GS - only allowed to account for 50% FC

Tailwind: Increases GS - account for 150% FC

12

Braking in wet conditions

WET LD = 1.15 x Dry LD

13

Downslope

1% downslope = 5% increase in LD

14

MAX Planned Length of RW used for LD

70% total RW: Prop
60% total RW: Jet
