The Altitude Hold Gain is used by the altitude hold control algorithm based on the ultrasonic sensor. The user should mount the sensor so
that it is pointing towards the ground and is not impeded by any wires or landing gear structures. Ultrasonic sensors have a wide beam width
and a simple dangling wire within the beam can cause a huge error.
To use the Altitude Hold Function, rise to a safe altitude that you would like the aircraft to maintain. Then activate the Altitude Hold Function
by turning the associated switch to on or enabled (position is user dependent). The aircraft will rise and fall within a range of altitude around
the chosen altitude. The pilot can increase or decrease the Altitude Hold Gain to increase or decrease the range of altitudes. The accuracy
of Altitude Hold depends on sensor configuration (hardware positioning), sensing surface, and other conditions. Typical operation is within a
few centimeters.
Adjusting Altitude while in Altitude Hold Mode
While Altitude Hold is enabled the throttle channel no longer adjusts the throttle level directly. Instead the throttle stick controls the altitude
based on the ultrasonic sensor. The user can change the altitude simply my increasing or decreasing the throttle.
