CAUTION
Use of automotive gasoline containing alcohol (e.g.: methanol or
ethanol) other than specified in the above listed specifications, is not
permitted.
Petroleum suppliers provide automotive gasoline of varying volatilities, depending on the season and climatic zone. Fuels with higher volatility (“cold weather” grade fuels) are more susceptible to fuel vapour formation than fuels with lower volatility (“hot weather” grade fuels), at equal temperatures. Use of fuels dispensed in winter or in colder climatic zones, under high ambient temperature conditions, increases the risk of vapor formation and subsequent possible engine malfunction.

4.3 STRUCTURAL TEMPERATURE INDICATOR
A structural temperature indicator, installed on the spar bridge, indicates when the structural temperature limitation is exceeded (ref. section 2.17). The indicator need only be checked if the OAT exceeds 38° C (100° F). The indicator is accessed by lifting the flap between the two seatback cushions. The indicator is visible through the cut out in the seat shell backs (ref. fig. 2). At temperatures below the 55° C (131° F) limit, the indicator appears all red with a faint indication of “55” (° C). At temperatures exceeding the 55° C (131° F) limit, the indicator displays a clearly contrasting red “55” (° C) on a black background (ref. fig.1).
NOTE
At temperatures approaching the limit, the background will progressively darken
prior to turning black; this indicates acceptable temperatures.
Red “55” on black background indicates that structural temperature limit is exceeded. Flight is prohibited.
All red indicates that structural temperature is below limit. Flight is permitted.

5.1. INTRODUCTION
The performance tables and diagrams on the following pages have been prepared to illustrate the
performance you may expect from your airplane as well as to assist you in precise flight planning. The
data presented in these tables and diagrams has been derived from test-flights using an airplane and
engine in good operating condition, and was corrected to standard atmospheric conditions [59° F (15° C)
and 29.92 in. Hg (1013.25 mbar) at sea level ].
The performance tables do not take into account the expertise of the pilot or the maintenance condition of
the airplane. The performance illustrated in the tables can be achieved if the indicated procedures are
followed and the airplane is in good maintenance condition.
Note that the flight duration data does not include a fuel reserve. The fuel consumption during cruise is
based on propeller RPM and manifold pressure settings. Some undefined variables such as the operating
condition of the engine, contamination of the aircrafts surface, or turbulence could have influences on
flight distance and flight duration. For this reason, it is of utmost importance that all available data is used
when calculating the required amount of fuel for a flight.
For flight operation without wheel fairings the resulting performance variations is given in %.
5.2. USE OF PERFORMANCE TABLES AND DIAGRAMS
The performance data is shown in the form of tables and diagrams to illustrate the influence of the
different variables. These tables contain sufficiently detailed information to plan any flight with the
necessary precision and safety on the conservative side.

NOTE
Poor maintenance condition of the airplane, deviation from the given procedures as well as unfavourable outside conditions (high temperature, rain, unfavourable wind conditions, including cross-wind) could increase the take-off distance considerably.
For take-off from dry, short-cut grass covered runways, the following corrections must be taken into account, compared to paved runways:
Doc # DA202-100-VLA March 19, 2004 Page Revision 3 5 - 7
Page 83
DIAMOND AIRCRAFT DA 20/100 Flight Manual Performance
Grass up to 5cm (2in) deep: 10% increase in take-off roll distance;
Grass 5 to 10cm (2 to 4in) deep: 15% increase in take-off roll distance;
Grass deeper than 10cm (4in): 25% increase in take-off roll distance.
On wet soft grass covered runways with grass deeper than 10cm (4in), the take-off roll distance might be increased by as much as 40%.

1. INTRODUCTION
To obtain the performance, flight characteristics and safe operation described in this Flight Manual, the
airplane must be operated within the permissible weight and balance envelope as described in Chapter 2.
It is the pilot's responsibility to adhere to the weight and balance limitations and to take into consideration
the change of the CG position due to fuel consumption.
The procedure for weighing the airplane and calculating the empty weight CG position are given in this
Chapter.
The aircraft is weighed when new and should be reweighed in accordance with applicable air regulations.
Empty weight and the center of gravity are recorded in a Weighing Report and Weight and Balance
Report as illustrated in the samples in figure 6.1 and 6.2. The actual report for the aircraft is at the end of
this chapter.
In case of equipment changes, the new weight and empty weight CG position must be determined by
calculation or by weighing and must be entered in the Weight & Balance Report. The following pages are
sample forms which can be used for airplane weighing, calculation of the empty weight CG position, and
for the determination of the useful load.
NOTE
After every repair, painting or change of equipment the new empty weight must be
determined as required by applicable air regulations. Weight, empty weight CG position
and useful load must be entered in the Weight & Balance Report by an authorized
person.

6.2. AIRPLANE WEIGHING
Pre-weighing conditions:
- equipment must be in accordance with the airplane equipment list
- brake fluid, lubricant (3.17 US qt / 3 liters), coolant (2.64 US qt / 2,5 liters) and
unusable fuel (0.53 US gal./ 2 liters), included
To determine the empty weight and the empty weight CG position, the airplane is to be positioned in the
above mentioned pre-weighing condition, with the nose gear and each main gear on a scale. Ensure the
aircraft is level longitudinally as illustrated on the weighing report (see figure 6.1).
With the airplane correctly positioned, a plumb line is dropped from the leading edge of each wing at the
root rib to the floor, join these two points to determine the reference datum (RD). From this line use a
suspended plumb line aligned with each landing gear to measure the distances D
main gear) and D
(right main gear).

6.3. WEIGHT AND BALANCE REPORT
The empty weight and Empty Weight CG position data determined prior to delivery of the airplane is the
first entry in the Weight and Balance Report. Each change of the installed equipment as well as each
repair affecting the empty weight, the CG position of the empty weight or the empty weight moment must
be entered in the Weight and Balance Report at the end of this chapter. The following Sample Weight
and Balance Report figure 6.2. is for reference only.
Ensure that you are using the latest weight and balance information when performing a weight and
balance calculation

6.4. FLIGHT WEIGHT AND CENTER OF GRAVITY
The following data enables the pilot to operate the DA 20/100 within the required weight and center of
gravity limitations.
The following diagrams,
Figure 6.3 Weight & Balance Diagram
Figure 6.4 Calculation of Loading Condition
Figure 6.5 Permissible Center of Gravity Range
and permissible Flight-
are to be used for calculations of the flight-weight and the center of gravity as follows:
1. The empty weight and the empty-weight-moment of the airplane should be taken from the
weighing report or from the weight & balance report and entered into the form "Calculation of
Loading Condition" (figure 6.4) in the columns identified with "Your DA 20".
2. Using the Weight & Balance Diagram (see figure 6.3) determine the moment for each part to be
loaded, and enter it in the respective column in figure 6.4.
3. Add the weights and the moments of each column (point 4 and point 6 in figure 6.4) and enter the
sum in figure 6.5 "Permissible CG Range and Permissible Flight-Weight-Moment" to check if the
values are within the permissible limits of the loading range.
