| Descent and Approach Profile Management
Inadequate management of descent-and-approach profile and/or incorrect management of aircraft energy level may lead to:
• Loss of vertical situational awareness; and/or,
• Rushed and unstabilized approaches.
Either situation increases the risk of approach-and-landing accidents, including those involving CFIT.
Approximately 70 % of rushed and unstable approaches involve an inadequate management of the descent-and-approach profile and/or an incorrect management of energy level; this includes:
• Aircraft higher or lower than the desired vertical flight path; and/or,
• Aircraft faster or slower than the desired airspeed.
To prevent delay in initiating the descent and to ensure an optimum management of descent-and-approach profile, descent preparation and approach briefings should be initiated when pertinent data have been received (e.g ATIS, …), and completed before the top-of-descent (typically 10 minutes before).
