CALLOUTS
 

The following information has been derived from the PS1.3  'Qantas' configuration file.

Pilot non flying (PNF) standard callouts:

Take-off roll

80 Kts   =  '80 knots'
V1         =  'V 1'
VR        =  'Rotate'

Climb/Descend/Level Change

Transition Altitude (Clb) = 'Transition - Standard set'   (Transition QNH to 1013 hPa/29.92 hg)

Transition Level    (Des) = 'Transition set' (back to QNH during descend)

1000 Feet To Go (Lvl Chg) = '1000 to go'  (at every change of altitude or level, 1000 ft before reaching assigned level (WATCH YOUR PROFILES  ;-)  )

Final Approach

Approaching Minimum Descend Alt (MDA) = '100 above'
Approaching Decision Height     (DH)          = 'Minima'
1000 ft Radar Altitude                                 = '1000'
500  ft Radar Altitude                                  = '500'
Runway in sight                                           = 'Visual'

Rollout

Rollout 80 kts = '80 knots'
Rollout 60 kts = '60 knots'
