In gliding within the United Kingdom, CBSIFT BEC[1] is the standard mnemonic to guide pilots through a series essential pre-takeoff checks.
Each letter in the acronym represents a specific component or procedure that must be verified to ensure flight safety Move each control individually, checking for full and free movements, with no restrictions.
If flying the aircraft solo, ensure the straps in the rear cockpit and will not interfere with any of the controls.
Check that the instruments are reading correctly, no broken glass and the panel is secure.
In the event of a launch failure, the glider must be flown at the minimum approach speed established for the prevailing wind conditions (for example 50, 55, or 60 kt).
If a landing ahead is not feasible, the glider must perform a downwind turn (using the appropriate side as indicated by the current wind) to complete an aborted circuit.
Should a wing drop be observed, the cable must be released immediately, and a landing ahead should be attempted.
This brought the checklist in line with common practice and acknowledged that pilots often want to leave the canopy open on sunny summer days, to avoid overheating, and on cold, humid winter days to avoid the canopy misting up.
