TOGA and missed-approach guidance

Press TOGA

Missed approach briefed ^[38]

Initiate TOGA

Use a stable practice approach with the missed approach briefed and sufficient fuel; do not practise after thrust-reverser deployment.

Press TOGA while airborne and maintain control. Check thrust and the vertical and lateral FMA indications.

FSS activation limits

GA / TRACK / actual path

Vertical GA and lateral

Compare the actual ground track with the published missed-approach path.

FSS says TOGA in the air engages vertical GA and lateral TRACK. The same page also lists a 2,500 ft radio-altitude activation limit, or 17,000 ft barometric altitude when radio altitude is invalid, without explaining how that limit relates to its summary.

FMA and flight path

TRACK / charted route

Do not assume TRACK follows the charted route. If the expected GA guidance is absent, fly the aircraft and published missed approach. Select the next lateral mode deliberately; cancelling vertical GA alone does not cancel TRACK. ^[10]
