A4 2.C1/C2/C3/C4
Objectives
The objective is for the aircraft to touch down within a marked deck, as close to the start of the deck as possible, coming to a halt in as short a distance as possible.
Summary
This task simulates a landing on an aircraft carrier deck, the deck being a deck 100 metres long and 25 metres wide. Deck length shall be adjusted according to the airfield elevation (S10 4.31.5). The width of the deck may be decreased to be adjusted to the width of the existing runway (S10 4.31.5). The first 25-metre section of the deck is divided into five 5 metre strips which are scored from 250 to 50 points as shown. The remainder of the deck scores 25 points. In order to score the main wheels must touch down in a particular strip and the aircraft must come to a complete halt within the 100-metre deck, as close to the start of the deck as possible.
Landing
Once the aircraft has started its final approach no deviation of over 90 ° from the deck centreline either in the air or on the ground is permitted and the engine must remain at idle or may be switched off. The aircraft must come to a complete standstill and must not move until instructed to do so by a marshal.
Scoring
The score will be the value of the strip in which both main wheels touch down with the ground (PS) plus the distance between the finish of the deck and the closest wheel, scored 1 point per whole metre (PD). Touching down on a dividing line scores the higher of the two strips.
The pilot will be scored zero if:
\- The aircraft commences takeoff before instructed to do so by the marshal
\- The engine is not stopped or the throttle is not closed before passing over the deck
\- The aircraft does not pass over the entire length of the deck before turning to descend
\- The engine does not remain at idle once final approach has started if engine idle permitted
\- The aircraft turns by more than 90 degrees from the deck centreline between starting the landing approach and coming to a standstill
\- Any part of the aircraft touches the ground before the deck.
\- The aircraft does not stop within the limits of the deck.
\- The aircraft moves from the deck before instructed to do so by a marshal
\- The aircraft is unable to taxi or take off unaided following the touchdown although failure to start the engine will not incur a penalty
Thus the score calculation will be (PS + PD) with a hypothetical maximum score of 350

A4 2.C1/C2/C3/C4
Objectives
The objective is for the aircraft to touch down within a marked deck, as close to the start of the deck as possible, -coming to a halt in as short a distance as possible.-
Summary
This task simulates a landing on an aircraft carrier deck, the deck being a deck 100 metres long and 25 metres wide. Deck length shall be adjusted according to the airfield elevation (S10 4.31.5). The width of the deck may be decreased to be adjusted to the width of the existing runway (S10 4.31.5). The first 25-metre section of the deck is divided into five 5 metre strips which are scored from 250 to 50 points as shown. The remainder of the deck scores 25 points. In order to score the main wheels must touch down in a particular strip -and the aircraft must come to a complete halt within the 100-metre deck, as close to the start of the deck as possible-.
Landing

Scoring
The score will be the value of the strip in which both main wheels touch down with the ground -(PS) plus the distance between the finish of the deck and the closest wheel, scored 1 point per whole metre (PD).- Touching down on a dividing line scores the higher of the two strips. {color:#ff0000}If the aircraft bounces after touchdown and jumps over more than 1 strip, the touchdown after the bounce is measured as the first touchdown for scoring.{color}
The pilot will be scored zero if:

\-{color:#ff0000}The aircraft touches the ground with any part other than the main wheels before touching with both main wheels.{color}

This proposal includes the same modifications to tasks 2.C2, 2.C3, and 2.C4.

h3. Reason
The short landing tasks are the most dangerous, leading to most accidents, putting a lot of strain on the aircraft undercarriages and are one of the reasons why not more participants are coming to the competitions. By removing this, we can attract new competitors and prevent practically all accidents.
By adding the restriction on bouncing and touchdown with the main wheels first, we encourage the pilots to execute a nice, low speed precision landing on the main wheels, instead of pushing the aircraft into the deck, sometimes nose wheel first and then braking hard. That will increase both safety and recognition of well executed landings instead of pushing the landing gear and the brakes to (or beyond) its limits.
