Regulated takeoff weight
 

Hi all
can someone tell me where to find a formal defination of regulated takeoff weight (RTOW).

thanks

See JAR-OPS 1.490.

'Maximum Permitted Take-Off Mass' is probably the eurospeak version of Regulated Take-Off Weight.

It is NOT the aircraft MTOW, of course.

As has never really been made well known, it appears that the AF Concorde which crashed on take-off at CdeG may have been slightly over its structural MTOW, but was considerably above its RTOW.....

4 TAKE-OFF WEIGHT LIMITATIONS - RTOW

4.1 For the purposes of paragraph 235 (2) (a) of the Regulations, the maximum weight that an aeroplane to which this section applies may not exceed at take-off is the least of the weights determined in accordance with
subparagraphs (a) to (d):

(a) a weight at which the take-off distance and accelerate-stop distance
required under subsection 6 for the aerodrome elevation, ambient
temperature, wind component along the runway, runway slope and runway
surface conditions at the time of take-off are equal to or less than the
take-off distance and accelerate-stop distance available in the direction of
take-off. Approved declared conditions may be used instead of the
ambient temperature and aerodrome elevation;

(b) a weight that will permit compliance with the take-off climb requirements
mentioned in subsection 7 taking into account either ambient temperature
and aerodrome elevation, or approved declared conditions;

(ba) a weight that will permit compliance with the obstacle clearance
requirements mentioned in paragraph 7.5 and subsection 12 for take-off
from a dry runway (whether it is dry or not), and taking into account either
wind conditions, ambient temperature and aerodrome elevation, or wind
conditions and approved declared conditions;

(c) a weight which will permit compliance with the en-route obstacle
clearance requirements specified in subsection 12;

(d) a weight which, allowing for normal consumption of fuel and oil in flight
to the destination and alternate aerodrome, will permit compliance the landing weight limitations mentioned in subsection 5.

5 LANDING WEIGHT LIMITATIONS -RLW

5.1 For the purposes of paragraph 235 (2) (b) of the Regulations, the maximum weight which an aeroplane to which this section applies may not exceed at landing is the least of the weights determined in accordance with
subparagraphs (a) to (c):

(a) a weight at which the landing distance required in accordance with
subsection 11 for the aerodrome elevation, wind component along the
runway, runway slope (when exceeding 1%) and runway surface
conditions at the time of landing, is equal to or less than the landing
distance available in the direction of landing;

(b) a weight which will permit compliance with the approach climb
requirements specified in subsection 9, taking into account forecast or
ambient temperature and aerodrome elevation or approved declared
conditions;

(c) a weight which will permit compliance with the landing climb
requirements specified in subsection 10 taking into account forecast or
ambient temperature and aerodrome elevation or approved declared
conditions.

Interesting to see a German poster quoting from the SUPERLATIVE Australian regulations. (Mind you, I'm not prejudiced :E ).

Sehr gut bulfly.
