VLO
Max Speed for Operating Gear
What does the danger category of brake usage mean you must do?
Clear the RWY, No Park Brake, Call Fire People, Brake Tyre and Wheel must be replaces
Touch down protection ensures that no brakes are applied on the approach and for touch down. What overrides it?
Wheel spin up on LDG
Wha is meant by swept wing growth
Geometry of ac when dist from centre of turn to wing tip is greater than CoT to Nose
Most dangerous area of an overhearted undercarriage assembly?
sides where wheel hub may explode
In a fully powered control system…
artificial feedback system is req’d
servo tab
used to trim ac from cockpit
balance tab
reduces aerdynamic forces on control surfacesa
Which statements are correct about autobraking?
1) AB will disconnect if any brake pedal is pushed.
2) AB irrelevant wrt throttle position
3) can be selectged in min, med, max
4) removes danger of aquaplaning
1 + 3
Are fully powered controls reversible?
No
fly by wire, signals between comp and PCU is XXXX, and b/w PCU and control surface, it is YYYY
XXXX - Elec
YYYY - Mech
What is a vibrating rod icing indicator
system where ice slow vib which is sensed and timed to give an indication
A de-icing system
removes ice once formed
an anti-icing system
prevents ice forming
Props protected from ice by:
- electrtical heater mats
- TKS
- Pneumatic mech boots
- theremal/ hot air
1 + 2
How does AL34 work as de-ice
70% AL34, 30% Hot Water
T or F:
1) Pure TKS is an anti-ice and de-ice
2) TKS flows along upper wing sfc only
F, T
what does rain repellant do
