Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.

How does an altimeter work and which errors can an altimeter experience?
How does an altimeter work and which errors can an altimeter experience?
When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.
This in turn moves the needle on the instrument to indicate a corresponding altitude.
During descent, the opposite function applies.
Altimeter errors can originate and vary from:
Instrument Pressure Time-lag Barometric Density Temperature Blocked static port
