The Gear Down call
Immediately below the table, you can select at which flap position
you would like to hear the Gear call by selecting the option beneath
the corresponding column. Alternatively, you can enter an altitude at
which to make the call. Setting the ‘Gear Down’ Altitude to ‘0’
makes the Gear Down call occur with the selected flap call. Setting
the altitude (different from ‘0’) makes the Gear Down call occur as
you descend below that altitude.
Flap position radio buttons Trigger ‘Gear Down’ call

Select the option corresponding to the flap call with which you wish

The altitude at which to make the Gear Down call

option. If you wish to make the Gear Down call occur at a given
altitude rather than following a given flap setting, you can enter the

Required:No
Let’s take the Boeing 737 as an example. Normally, the Gear Down
call is made when the Flap 25 call is made. This is achieved by
entering ‘0’ in the ‘Gear Down’ Altitude box, and select the option
beneath the F25 column. If you would rather hear the call when you
pass 2500 ft during your descent, simply enter ‘2500’ in the ‘Gear
Down’ Altitude box.
Flap calls
Just like the Gear Down call, flap calls can be triggered in two ways.
They can either be based on airspeed (IAS), and will in that case use
the data entered in the table above. Alternatively, the call can be
made based on the altitude of your aircraft. In the lower section of
