Please explain what is RTOW, and what is the difference between RTOW and MTOW. Is there a link between the RTOW and the Weight and Balance Manual?

    $\begingroup$ @Farhan I don't think that question mentions RTOW? This one does, but only indirectly and it doesn't give a definition. $\endgroup$

1 Answer 1


Google gives you the answer without even clicking any links:


MTOW is a hard limit regardless of other considerations and is tied up with the basic aircraft certification basis.
RTOW is the limiting takeoff weight calculated for a particular runway under particular specified conditions

Maximum Take Off Weight - The maximum weight in which an aircraft can ever take-off, under any circumstances.

Regulated Take Off Weight - The maximum weight in which an aircraft can take off from a particular runway under specific conditions (winds, weather, specific aircraft configuration, etc,). For example, runway 29 at KXYZ airport with ambient temp of 20° C. This can get as specific as you wish.

Of course $RTOW \le MTOW$.

    $\begingroup$ In addition, there is no direct relation between the RTOW and the weight and balance manual (WBM), other than that limits specified in the WBM might impose a restriction which the RTOW would have to consider. $\endgroup$ Nov 15, 2017 at 16:11
