A Takeoff Acceleration Monitoring System automates the pilot monitoring of Distance to Go (DTG), "to sense, in a timely fashion the development of insufficient acceleration, which would extend the takeoff roll, perhaps precipitously".
Over the years, recommendations have been made to develop a Take Off Performance Management System. The NLR and NASA developed TOPMS prototypes. However, these systems were never operationally introduced.
EASA established two working groups (WGs) to address this issue. WG-88 focussed on the specification and standardization of On-Board Weight and Balance Systems
(OBWBS), an ongoing effort for what is considered to be a feasible option. WG-94 focussed on standards and operational conditions for a TOPMS; it WG-94 was concluded early 2017, considering that TOPMS was not feasible, in particular due to limitations in technology and data availability.
A version suitable for detecting gross errors, which can be integrated in existing avionics, has been proposed by
National Aerospace Laboratory (NLR),
KLM, and
Martinair
Martinair (legally ''Martinair Holland N.V.'') is a Dutch cargo airline headquartered and based at Amsterdam Airport Schiphol and a subsidiary of Air France–KLM. The airline was founded in 1958 by Martin Schröder. Since 2011, Martinair has o ...

A 2019 research paper explores the cause of a
July 2017 serious incident, caused by erroneous data entry, where such system could have been useful. It "summarises a basic takeoff acceleration monitoring system and the effect this would have had on the July 2017 event".
