Narrative:

On jul/xx/94 I was in command of flight from den to rap departing at xxoo pm local time. The temperature was quite warm so we were dealing with weight restrs. In an effort to carry as much as possible I was hoping that cloud cover would move over the field to drop the temperature. I guessed it would drop about 5 degrees giving me a much better weight restr. The flight was booked full (30 passenger). After the passenger loaded, the flight attendant informed me that there appeared to be 5 half weight passenger (under 12 yrs of age) giving me a 400 pound break on weight. There were delays for inbound flts so connecting bags were having trouble getting to us, I was informed by rampers that we had about 20 bags and some freight on board. After this count I did see a couple of carts pull up but I was not given an updated count so I left it as is. My fuel was loaded so I used a liberal taxi burn to bring the fuel weight down to minimum weight at takeoff for VFR reserves. It is my opinion that in an effort to carry as much payload as possible I used several gray performance figures that, if added up as worst case, could put the aircraft in an overweight condition. All crews should keep this in mind when checking aircraft performance data to insure a safe flight.

Title: ACFT GROSS WT EXCEEDED IN TKOF PROC.

Narrative: ON JUL/XX/94 I WAS IN COMMAND OF FLT FROM DEN TO RAP DEPARTING AT XXOO PM LCL TIME. THE TEMP WAS QUITE WARM SO WE WERE DEALING WITH WT RESTRS. IN AN EFFORT TO CARRY AS MUCH AS POSSIBLE I WAS HOPING THAT CLOUD COVER WOULD MOVE OVER THE FIELD TO DROP THE TEMP. I GUESSED IT WOULD DROP ABOUT 5 DEGS GIVING ME A MUCH BETTER WT RESTR. THE FLT WAS BOOKED FULL (30 PAX). AFTER THE PAX LOADED, THE FLT ATTENDANT INFORMED ME THAT THERE APPEARED TO BE 5 HALF WT PAX (UNDER 12 YRS OF AGE) GIVING ME A 400 LB BREAK ON WT. THERE WERE DELAYS FOR INBOUND FLTS SO CONNECTING BAGS WERE HAVING TROUBLE GETTING TO US, I WAS INFORMED BY RAMPERS THAT WE HAD ABOUT 20 BAGS AND SOME FREIGHT ON BOARD. AFTER THIS COUNT I DID SEE A COUPLE OF CARTS PULL UP BUT I WAS NOT GIVEN AN UPDATED COUNT SO I LEFT IT AS IS. MY FUEL WAS LOADED SO I USED A LIBERAL TAXI BURN TO BRING THE FUEL WT DOWN TO MINIMUM WT AT TKOF FOR VFR RESERVES. IT IS MY OPINION THAT IN AN EFFORT TO CARRY AS MUCH PAYLOAD AS POSSIBLE I USED SEVERAL GRAY PERFORMANCE FIGURES THAT, IF ADDED UP AS WORST CASE, COULD PUT THE ACFT IN AN OVERWT CONDITION. ALL CREWS SHOULD KEEP THIS IN MIND WHEN CHKING ACFT PERFORMANCE DATA TO INSURE A SAFE FLT.
