Vsi Flashcards
1
Q
Meter unit
A
Divides flow into turbulent (knife edge/ orifice) And laminar ( capillary)
Keeps the flow rate constant and keeps the delay to 4 secs
2
Q
To stop the lag
A
IVSI uses a bob weight
3
Q
Blockage in the static line for a VSI
A
Constantly show 0 as the capsule will equalise
4
Q
Leak in the static line VSI
A
Pressurised - will show 0 due to the cabin being kept at 6,000
Unpressurised - will not be effected much
5
Q
IVSI
A
A piston is moved due to the inertia of vertical climb
Allows more/ less static pressure to reach the capsule quickly and reduces lag
