SCHEMPP-HIRTH FLUGZEUGBAU <strong>GmbH</strong>., KIRCHHEIM/TECK Duo Discus MAINTENANCE MANUAL 6.6 Useful load Load on the seats a) Water ballast fin tank not installed Note: (*) Depending on its equipment and the installation of fixed trim ballast, the actual minimum and/or maximum seat loads of this “Duo Discus” (to which this manual refers) may differ from the above typical weights. The placards in the cockpit must always show the actual weights, which are also to be entered in the log chart – see flight manual, page 6.2.3. Neither the maximum permitted all-up mass nor the maximum mass of the non-lifting parts must be exceeded. Determination of the maximum permitted load on the seats: Flown solo: Two occupants: SEAT LOAD front seat load rear seat load LOAD ON THE SEATS (crew incl. parachutes) TWO PERSONS min. max. 70* kg 154* lb at choice Maximum cockpit seatload 110* kg 243* lb 110* kg 243* lb Always 110 kg (242.5 lb) ONE PERSON min. max. 70* kg 154* lb 110* kg 243* lb Maximum cockpit load (load on both seats) may not be exceeded. For seat loads below the placarded minimum refer to Flight manual - section 6.2 The total of the loads on front and rear seat has to be lower than the maximum cockpit seatload. At the same time pay attention, that the load on each seat stays below 110 kg (242.5 lb) Maximum seat load: This is the difference between the maximum permitted mass of the non-lifting parts (440 kg / 970 lb) and their actual mass (refer to last weighing report). b) Water ballast fin tank installed Note: SEAT LOAD front seat load rear seat load LOAD ON THE SEATS (crew incl. parachutes) TWO PERSONS min. max. 100 ** 220 kg 100 ** * ** lb 110* 243* kg 220 * kg ** lb ( 70* kg) lb ( 70* kg) (154* lb) (154* lb) 110* at choice 243* kg lb Maximum cockpit seatload ONE PERSON min. max. 110* 243* kg lb Maximum cockpit load (load on both seats) may not be exceeded. For seat loads below the placarded minimum refer to Flight manual - section 6.2. The value shown in parenthesis may be used after having thoroughly checked the ballast quantity in the fin tank and the appropriate loading chart. (*) Depending on its equipment and the installation of fixed trim ballast, the actual minimum and/or maximum seat loads of this “Duo Discus” (to which this manual refers) may differ from the above typical weights. If so, the log charts and the placards must be altered accordingly. (**) 1. For safety reasons the minimum seat load for flights with empty fin tank must be increased by 30 kg (66 lb) so as to allow for an unnoticed filled fin tank. 2. Adding the mass of 30 kg (66 lb) is not required, however, if the pilot either - dumps all water ballast (prior to take off) or - determines the ballast quantity in the fin tank and ensures that it is compensated by an appropriate load in the wing tanks and/or on the aft seat. The placards in the cockpit must always show the actual weights (including those allowing for a filled fin tank **), which are also to be entered in the log chart – see flight manual, page 6.2.3. Neither the maximum permitted all-up mass nor the maximum mass of the non-lifting parts must be exceeded. February 2008 MB-No. 396-15 / TN-No. 396-13 Revision 20 TN-No. 396-16 (x) 6.6.1
