What is the purpose of a VSI?
To indicate whether the aircraft is climbing or descending
To measure the pressure differential
To maintain the airspeed

With the use of VSI, what will happen when the aircraft climbs?
The capsule expands and static pressure drops
The diaphragm will contract and the pressure will drop faster
There will be radio signals
What are the errors that VSI gives?
What will happen to the needle of the VSI when the pressures are equalized in level flight?
