+# 1. Goal
+A drone delivery operator checks a delivery request before it releases a drone.
+The dispatch program calls one check for each request. The program needs one
+reason code for each request and the battery charge that the flight needs.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The interface {{P}}IF_DRONE_CHECK exists in package $TMP. It is active.
+- The interface has the types TY_REASON (character, length 10), TY_WEIGHT
+  (packed number, length 8, 2 decimals), TY_DISTANCE (packed number, length 8,
+  2 decimals), TY_SPEED (packed number, length 8, 2 decimals) and TY_PERCENT
+  (integer).
+- The interface has the constant structure C_REASON with the components OK,
+  PAYLOAD, DISTANCE, WIND, BATTERY, ZONE and LIGHT.
+- The interface has one method:
+  CHECK
+    IMPORTING iv_payload          TYPE ty_weight
+              iv_distance         TYPE ty_distance
+              iv_wind_speed       TYPE ty_speed
+              iv_battery          TYPE ty_percent
+              iv_in_zone          TYPE abap_bool
+              iv_daylight         TYPE abap_bool
+    RETURNING VALUE(rv_reason)    TYPE ty_reason.
+
+# 4. Contract
+- Create the class {{P}}DRONE_CHECKER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- The class implements {{P}}IF_DRONE_CHECK.
+- The class has the public method REQUIRED_BATTERY:
+  IMPORTING iv_distance TYPE {{P}}IF_DRONE_CHECK=>TY_DISTANCE
+  RETURNING VALUE(rv_percent) TYPE {{P}}IF_DRONE_CHECK=>TY_PERCENT.
+- Do not add other public methods.
+
+# 5. Business rules
+The payload is in kilograms, the distance in kilometres, the wind speed in
+metres per second, and the battery charge in percent.
+The check applies the rules in this sequence and returns the reason of the
+first rule that fails.
+1. If the payload is less than or equal to zero, or greater than 5.00, return
+   PAYLOAD.
+2. If the distance is less than or equal to zero, or greater than 20.00, return
+   DISTANCE.
+3. If the wind speed is greater than 12.00, return WIND.
+4. If the battery charge is less than the charge that the flight needs, return
+   BATTERY.
+5. If iv_in_zone is abap_false, return ZONE.
+6. If iv_daylight is abap_false, return LIGHT.
+7. Else return OK.
+The charge that a flight needs is the result of REQUIRED_BATTERY:
+- If the distance is less than or equal to zero, the result is 0.
+- Else the result is 2 percent for each started kilometre plus a reserve of
+  10 percent. A started kilometre counts as a full kilometre.
+
+# 6. Constraints
+- Release target: SAP_BASIS 816 (ABAP Platform 2025).
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}IF_DRONE_CHECK.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
