1.4 Brief Description
1.4.1 Aircraft type
The Apollo Fox type powered microlight is the first aerodynamically controlled aircraft produced by Halley Ltd. After producing hundreds of weightshift controlled aircrafts the birth of Apollo-Fox was a turning point in the profile of the Company. Many years of experiences gained during the production and operation of other Hungarian aircraft types helped us in the contemplation and construction. On development,besides small size, quick assembly and easy transportation, price reduction was a primary aspect. Neither maintenance staff nor established aerodrome is required for operating the aircraft. The aircraft is designed as a high-wing monoplane supported by struts. A two-spar wing is provided with flaperon. The spars and load bearing elements are made of high strength steel tubes. Fuselage is a lattice-work of steel tubes. The tail unit is made of a lattice-work tube frame. Landing gear is of a conventional type, with a nose gear.
1.4.2 Propeller
The propeller is of a conventional two-three-four bladed, tractor, rotating in clockwise direction. It is made of wood and/or plastic, or composite type fixed pitch or ground/air adjustable propeller and has a strengthened leading edge. The propeller type for each serial number is depends on the order made by the plane’s owner.
1.4.3 Power Unit
The Apollo Fox microlight is powered by Rotax 912UL,or ULS engine. It is an opposed cylinder, four-stroke, four-cylinder, centre cam shaft engine with over-head valves. Cylinder heads are water­cooled and cylinder air-cooled. Lubrication system is of a crank case type. The ignition system is of a dual ignition type. The engine is equipped with an electric starter, DC generator, fuel delivery pump and voltage regulator. The propeller is powered from an integrated reduction gearbox.
WARNING
This engine
is not

Link tank ............................................................. 6 l
Max. fuel quantity ............................................... 66 l
Usable fuel quantity ............................................ 60 l
Unusable fuel quantity on ground ....................... 6 l
Unusable fuel quantity in the air with engine on...2 l
Fuel specification unleaded Minimum ............. RON 95
in accordance with DIN 51607
CAUTION
! The fuel tanks (wings+center tank) contains 6 litres of fuel after complete
defueling on the ground. This amount is the unusable fuel quantity on ground. In the air with operating engine the unusable fuel is 2 litres. The engine can completely empty the center link tank.
Page 19
19
The fuel system includes two wing tanks of 30 l fuel capacity each, a link tank of 6 l capacity , drain cock, fuel cocks, a fuel filter, an engine fuel pump, electric fuel pump and connecting line.
The fuel is gravity flown from the right-hand or left-hand wing tank into the link tank depending which wing tank fuel cock is open. The fuel is then further directed from the link tank via the main fuel cock and fuel filter into the fuel pump on the engine which delivers the fuel to carburettors. The amount of fuel in tank is indicated by a fuel gauge which is a part of every tank. Minimum fuel quantity in the link tank is indicated visually by lighting up a warning light on the instrument panel. The remaining fuel, i.e.6 l, is in that case enough for 15 minutes of flight. The drain cock outlet is connected to the link tank to drain off water and dirt. It is not advisable to change the used type of gasoline during engine operation.Since fuel will be in most cases refuelled from a barrel or a fuel can and not from the filling pump, it is necessary to pay a due attention to this activity. Refuelling should be carried out in places not endangering either the aircraft, its attendance or environment. Prior to refuelling it is always necessary to check gasoline for absence of water. Sampling should be done both from the transportation containers and from tanks and aircraft fuel system through drain sump. When refuelling, a funnel must be used provided with a strainer to trap impurities or even better, with a buckskin leather which can trap also eventual fuel moisture content. Fuel dumping is performed similarly as sampling by means of a drain cock. When filling fuel into tanks, be careful to avoid staining of cockpit window panels and glass with fuel as it contains corrosive components that will cause a fast deterioration and damage to cockpit glazing.

3.1.5.15 Landing
At a height of about 10 m reduce the engine speed to idle. Maintain speed of 90-100 km/h till flattening-out. When floating at a height of 0.5 -1 m above ground, decelerate gradually by pulling the control stick backward. At a speed of about 60 km/h the aircraft touches-down on main wheels. At landing run it is necessary to hold the elevator up and to apply brakes with feeling, keeping in mind a potentiality of turning the aircraft over on propeller. At wind speed over 7 m/sec it is advisable to land with increased idle.

3.2.1 Introduction
Chapter 3.2 contains procedures for various emergencies which may occur. A thorough performance of maintenance system should prevent occurrence of such extreme cases.
The chapter describes basic emergencies and procedures for their solving. Not all emergencies that may occur can be listed here in full, therefore their solution depends on experience of the crew controlling course of such events.
3.2.2 Engine Failure
3.2.2.1 Engine Failure at Take-Off Run
- throttle reduce to idle
- ignition switch off
- apply brakes
3.2.2.2 Engine Failure at Take-Off
- speed 110 km/h IAS
- choice of landing area - after take-off and up to 50 meter land
in direct straight ahead if possible
in direct straight ahead if possible
- over 50 m: choose landing area The landing area is to be preferably chosen in direction of free runway or a free
clear area, upwind, if possible.
- master switch switch off
- ignition switch off
- main fuel cock shut
- tank fuel cocks change over to shut position
- wing flaps extend as required
- safety belts tighten
3.2.2.3 In Flight Engine Failure
- airspeed 110 km/h IAS
- area selection depending on flight altitude
- master switch switched on
- ignition switched on
- main fuel cock open

- throttle set for start
- starter start the engine if the engine cannot be started up, proceed in accordance with 3.2.2.2.
procedure
.
3.2.3 Carburettor Icing
Carburettor icing mostly occurs when getting into an area of ice formation. The carburettor icing shows itself through a decrease in engine power and an increase of engine temperatures and drag. To recover the engine power, the following procedure is recommended:
use carburetter preheating system
- airspeed 80 - 90 km/h IAS
- throttle max. at 1/3 of power (3500 r.p.m.)
- if possible, leave the icing area
- increase gradually the engine power to cruise conditions after 1-2 minutes if you fail to recover the engine power, land on the nearest airfield (if feasible) or
depending on circumstances, off-airfield, following the procedure given under
3.2.2.2.
3.2.4 In-Flight Engine Starting
- airspeed 110 km/h IAS
- area selection depending on flight altitude
- master switch switch on
- main fuel cock open
- choke switch on (cold engine only)
- throttle adjust to 1/3 of travel
- ignition switch on
- starter start up
- if the engine cannot be started up, increase the flight speed to 140-150 km/h so that air flow can rotate the propeller, thus enabling engine starting.
CAUTION
Loss of height needed for in-flight engine starting is about
150 -200 m.

3.2.5 Engine Fire, Fumes in the Cockpit
Recommended procedures to follow, when fire or fumes in engine compartment and cockpit are detected.
3.2.5.1Ground Fire
- main fuel cock shut
- throttle full throttle
- ignition: switch off after using up fuel in carburettors and engine stopping
- master switch switch off
-abandon the aircraft and extinguish fire (if possible)
3.2.5.2 Fire during take-Off
- throttle idle
- main fuel cock shut
- tank fuel cocks shut
- airspeed 100 - 110 km/h and land
- brakes stop
- throttle full cruise
- ignition switch off after using up fuel in carburettorsand engine stopping
- abandon the aircraft and extinguish fire (if possible)
3.2.5.3 In-Flight Fire
main fuel cock shut
- tank fuel cocks shut
- throttle full travel
- landing area selection guide the aircraft to an airfield,
or choose an area for emergency landing
- ignition switch it off after using up fuel in carburettors and engine stopping
- master switch switch off
- airspeed extend as needed
- safety belts tighten
- perform emergency landing
- abandon the aircraft and extinguish fire (if possible)-
NOTE
Time needed to pump fuel out of carburettors is around 30 sec.

3.2.6 Descent, Gliding
- airspeed 110 km/h
- throttle increased idle
- wing flaps retracted
- engine instruments values within permitted limits
CAUTION
At long final and when descending from a considerable height, it is not advisable to reduce the engine throttle control to minimum. In such case the engine becomes undercooled and a loss of power occurs. When descending, apply increased idle so that engine instrument readings range within the limits for normal use.
gliding ratio ......................................................... 1 : 14
optimum gliding speed ................................ 100 km/h IAS
sinking ................................................................ 2.3 m/s
3.2.7 Emergency Landings
Recommended procedures for various types of emergency landing.
3.2.7.1 Precautionary Landing
- choose landing area, evaluate wind direction and speed, area surface,
surrounding obstacles and total safety of the manoeuvre under consideration
- perform approach and fly-over at a speed of 95 km/h along the deliberate area
at a height of 50 m to estimate the area condition, obstacles and to determine magnetic course of landing
- make orbiting approach to land
- perform landing from the very beginning of the chosen are
a
3.2.7.2 Blown-Out Tyre Landing
- carry out normal approach-to-land
- when floating at landing, keep the damaged wheel above ground as long as
possible using ailerons
- maintain the direction at landing run, applying foot control
3.2.7.3 Damaged Landing Gear Landing
-carry out a normal approach-to-land
-if the nose wheel is damaged, perform a touch-down on main wheels and hold the aircraft on wheels as long as possible till the speed is lost
-if the main landing gear is damaged, perform touch-down at the lowest speed possible and maintain direction at landing run, if possible
Page 35

3.2.8 Vibrations
If any forced vibrations appear in the aircraft, it is necessary:
- to set engine speed to such power rating where the speed is lowest
- to land on the nearest airfield, or to perform a precautionary landing off-airfield
- if the vibrations are increasing, carry out an emergency landing off-airfield, following procedures given under 3.2.2.2.
