Service Alert 1947 Rev B: Takeoff/Landing Distance (TOLD)

REVISION B:

Added Resolution

PRODUCTS AFFECTED:

All G3000 and G5000 systems with TOLD are affected.

ISSUE:

Some runways have an Accelerate and Stop Distance Available (ASDA) that is shorter than the Takeoff Run Available (TORA). For these runways the TOLD function uses the wrong data to determine available takeoff runway length.

PILOT ACTION:

Refer to the Aeronautical Information Manual (AIM) for additional details on TORA and ASDA. Review the runway distance value used by TOLD for takeoff calculation and manually override if a shorter ASDA field distance is charted for the runway.

RESOLUTION:

This issue is fixed in Navigation Database Cycles 1912 (effective 11/7/19) and later.
