1. Introduction
In the past 25 years experts of the HALLEY LTD, EGER have designed and
developed approximately 40 types of weight shift controlled (WSC) UL aircrafts,
while basically applying the experiences obtained during manufacturing and
operating the WSC aircraft types Apollo CX and Apollo C15 Racer GT but the
knowledge gained on the other, more than 10 types produced in preceding period
were of course utilized, also. Due to streamlining the cockpit aerodynamically
advantageous and aesthetically favorable designs were produced, while the
introduction of telescopes on all wheels, hidden tanks, topless wing structure, higher
motor selection, vibration dampers, strutted wings and other improvements made
Apollo aircrafts successful examples of advanced engineering.
The purpose of these changes was an aerodynamically favorable design with a high
glide ratio resulting an increase in speed and a decrease of fuel consumption. As a
result of all these developments the Apollo C15 DD - Delta Jet 2 –912 WSC
aircraft type of today is a safe, high performance, economic, durable, comfortable
and easily controllable aircraft on the top of the international UL market, applicable
on the whole range of UL operation from hobby to competition flying, which have
proved its capabilities on several international championships.
Please read this manual and get convinced that you can apply all what concerns
your Apollo C15 DD - Delta Jet 2 –R912 ultralight even before initiating its
operation.
Regular maintenance is required to keep your ultralight in a safe condition.
Maintenance requirements are listed in this Manual. Please refer to these parts of
this document to ensure that the airworthiness of your ultralight is maintained
continuously.
The operating procedures published in this Manual are the result of Apollo
knowledge and experience gained since 1979. Not only for legal flying
circumstances but also for the safety of your body, your aircraft and the environment
of your flights please, keep these procedures,

3. How to use the MANUAL
This manual is an official document prepared by Apollo Ltd, and must not be
amended or altered without the permission of the company. This manual is intended
neither to teach the owner how to fly the aircraft, nor to publish detailed information
about the basics of strength, control and stability of weight shift controlled (WSC)
aircrafts. Training is to be accomplished by a flying instructor licensed and rated to
instruct on this type of aircraft.
This manual is the property of the aircraft owner with the identification marks listed in
Chapter 2. At every flight this document is to be held in the appropriate pocket of the
cockpit and is to be presented to the authorities if requested.
This manual contains factory recommended procedures and instructions for
servicing, inspecting, maintaining and altering. Apollo C15 DD - Delta Jet 2 –912
WSC ultralight aircraft. The procedures described in it are to be used in addition to
the regulations of the particular governing body for each country where the aircraft is
flown. The handbooks of some Aircraft Primary Structures complete this present
basic manual, see Annexes. Legally these complementary manuals are of the same
value and of the same purpose as this present basic manual. Any problem emerges
covered neither by the rules in this Manual, nor the rules of the particular governing
body of the relevant country the prescriptions of the British Civil Aviation Regulations
Chapter „S” is to be referred to.
The information in this manual is based on the data that was available at the time of
its publication. The latest amendments to this manual will be mailed to the operators
either directly or via persons keeping constant contact with Apollo (Dealers and Type
managers, see: 5.3)together with the instructions on the actions to be done, and on
the way of annexing the amendment leafs to the aircraft basic Manual of the aircraft
owner. The AMENDMENT RECORD SHEET (see: Chapter 4) should at that time be
updated with the appropriate details and data. If any errors or omissions are found in
this Manual please, advise the factory.
It is assumed that only people with an adequate skill level will perform maintenance
on this aircraft. A sound understanding of mechanical systems, experience with the
necessary tools and procedures and knowledge of the specific flight mechanics of
WSC aircraft is required as the airworthiness of the aircraft depends on the
competence of the person performing the maintenance. If there are any doubts
regarding the required and appropriate maintenance then let Apollo Ltd or its dealer
be contacted for the correct procedures and/or servicing.
Before the beginning of operation the level of skill of the operator is to be controlled
by examiners designated either by Apollo (he may be the „dealer” if entrusted by
Apollo), or officials licensed and rated in the legal way valid in the country to state
and sign the relevant type-rating into the flight log book of the aircraft owner.
Warranty of Apollo is lost by any aerial operation, inspection, maintenance and
alteration action contradicting to any of the measures of this MANUAL. Warranty is
upheld only if measures of the MANUAL do not got offended.

5. General description of Apollo WSC aircraft
5.1 Aircraft Primary Structures (AP Structures)
All WSC aircraft is a combination of the Aircraft Primary Structures, that is
wing, trike, engine, propeller, BRS (optional)
Practice has proved that AP Structures can be of different types. A certain WSC
aircraft type is a defined variation of four airworthy AP structures (only the fifth being
optional). This way a wing can be paired with different trike, motor and propeller.
The aircraft composed of a defined variation of AP structures is airworthy only if
Apollo declares this fact, after fulfilling the relevant prescriptions of the authorities.
This present Manual defines one aircraft type with the following AP structures:
- Apollo C15 DD wing,
- Delta Jet 2 trike,
- Rotax 912 motor,
- PPP propeller.
- BRS (optional)
The airworthiness of Apollo C15 DD - Delta Jet 2 - R912 aircraft-type is declared on the
title page of this present Manual. The identification marks of the owner’s machine are
designated in Chapter 2.
As any change within a set of AP structures may alter the characteristics of the aircraft
with special attention to the operation limitations the airworthiness (see: 8) of the new
variation is to be declared by Apollo. If an owner intends to operate his aircraft with a set
of AP structures containing one or several AP structures outside of the set approved to
the type, he is to request the permission of the Apollo Ltd. As a response the Apollo
- insert a note into the Manual on page Technical Amendments Record Sheet, with the
leaflet describing the variation annexed, or
- publishing a new manual with altered LIMITATIONS,
- or may refuse its approval.
An alteration of this kind may generate a number of technical modifications, control
measurements and test flights together with the necessary documentation the price of
which all may charge the operator.

5.2 Aerial and Ground Operation
5.2.1: Aerial Operation
Aerial Operation (flying) of Apollo WSC aircrafts is considered to be legal by Apollo
only if the pilot disposes of a valid WSC licence with the relevant type rating.
5.2.2 Ground Operation (GO)
Concerning ground operation Apollo defines here two types of activity:
Heavy Ground Operation (H)—any maintenance, inspection, repair, or alteration,
which Apollo designated to be „heavy” ones, and require
- specific training and licensing (e.g. flight mechanic), or
- professional equipment (e.g. sail stitching tools) or
-special facilities (e.g.: workshop)
The pilot cannot make these activities independently. To find the proper way to carry
out the tasks excluded from the pilot’s activity appropriate licensed and type-rated
assistance is to be used.
Light Ground Operation (L)—any repair, maintenance, scheduled checks, servicing,
inspections, or alterations, which are not designated to be heavy ones by Apollo.
As the items of a Pre-flight Check are not qualified as „Heavy” ones, the pilot may do
them. This right of him terminates if during the Pre-flight Check a component is
discovered which requires special means.
5.3 Assistance for Ground Operation
To handle questions emerging while planning aircraft maintenance, inspection,
repair, or alteration Apollo stays at the disposal of the costumer by keeping contact
with him either directly, or by a Contact Person.
Contact Person for a costumer from a foreign country operating his/her aircraft
privately is the Dealer. The Dealer is the sole and exclusive representative of Apollo
Ltd in this country. The basic purpose of the assistance provided by the Dealer is the
fulfillment of the prescriptions of the Apollo while the regulations of WSC aircraft
operation valid in the county are also complied with, if possible simultaneously.
Description of this assistance is detailed in the Certificate of Appointment prepared
by Apollo for the dealer.
Contact Point for a costumer operating his/her aircraft under the supervision of an
Operating Organization is the Type Manager appointed by the relevant technical
leader of the Organization (mostly the Chief Engineer). Detailed description of this
assistance is an agreement between Apollo and the Operating Organization only if
such a document is required by any of the parties.

5.4 Aircraft Secondary Structures (AS Structures)
All AP Structures are composed of AS Structures. An AS Structure may operate with
different Components (Parts), however an AS Structure is airworthy only with the parts
ordered and received directly from Apollo or are declared by Apollo to be applicable.
Any change on an AP or an AS Structure without the approval of the Apollo Ltd may
generate legal consequences, especially if an aircraft accident or flying incident occurs
and the investigation reveals causes in connection with aircraft airworthiness.
In order to find the way among the actions which are to be followed during inspection,
maintenance and repair AS Structures are listed in 5.4.1 –5.4.5. together with their
ground operation type (Heavy/Light, requirements see: 5.2). For the sake of discovering
hidden damages, faults or discrepancies when preparing any inspection the aircraft is to
be precedingly cleaned and attended.
When inspecting, maintaining, repairing and altering the data in 9.3.5 Component
replacement schedule is to be considered.
