Part 7

Aerobatics and Formation Flying

Page 2: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

Aerobatics

Aerobatics

Give pilots confidence in handling aircraft.

They gain experience at operating in different attitudes.

Pilots become accustomed to the high strainsand stress of combat flying.

Page 3: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

Aerobatics

Before any aerobatic flying,a pilot must carry out his HASELL checks:

H

A

S

E

L

L

Height – sufficient to complete manoeuvre.

Airframe – Flaps and U/C UP, Airbrakes IN.

Security – Equipment stowed, harness locked and tight.

Engine – Temperatures, pressures & fuel sufficient.

Location – Airfields, built-up areas controlled airspace.

Lookout – clear of other aircraft & cloud (↔ & ↕)

Page 4: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsAs you should already know,

an aircraft can be manoeuvred in three planes:

Pitching plane

Rolling plane Yawing

plane

Page 5: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThe simplest aerobatic manoeuvre

in the pitching plane is the loop.

Pitching plane

Page 6: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsPilot aligns with linear feature – road, rail

Drop nose to increase speedKeep wings level

Pull up until horizon disappears, looking overhead for new horizon

Page 7: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThe simplest aerobatic manoeuvre

in the rolling plane is the barrel roll.

Rolling plane

Page 8: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsDrop nose to increase speed

Pick point above horizon (cloud)Roll 45° away from banking direction

Roll in banking direction,with nose of aircraft pointing at point on horizon

Page 9: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsIn the yawing plane

the only basic manoeuvre is the stall turn.

Yawing plane

Page 10: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsNose up to 90°, decreasing speed

Apply rudder before wing stalls.

Aircraft falls sideways until nose is pointing downSpeed increases,

round out at the bottom.

Page 11: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThere are other manoeuvres . . .

The Slow Roll As a barrel roll, but slower

Roll off the Top ½ loop followed by barrel roll or slow roll at the top

½ Roll and Pull Through Barrel roll or slow roll followed by a ½ loop

Page 12: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThere are other manoeuvres . . .

The Upward Roll Pull up vertically, roll keepingwings straight.Often ends with stall turn

Aileron Turn A roll flown vertically downward

Hesitation Roll Either a 4 or 8 point roll,stopping briefly every 45° or 90°

Derry Roll A roll flown while inverted

Page 13: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThere are other manoeuvres . . .

Vertical Eight A ½ roll off the top, a full loopand a ½ roll and pull through.

Page 14: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

AerobaticsThere are other manoeuvres . . .

Horizontal Eight A loop and a ½ roll, followed by another loop and ½ roll

A full roll on the first loop and½ roll into the second loop.

Cuban Eight

Inverted FlightAircraft flying inverted

appear to be flying with the nose well above the horizon.

Aircraft wings are less efficient inverted, so a higher angle of attack is required

for inverted straight and level flight.

Formation FlyingThe RAF’s definition of formation flying is:

‘An ordered arrangement of two or more aircraftproceeding together as an element.’

There are two types of formation flying:

Close TacticalTake-off & Landing

Cloud penetration

Show and Display flying

Used for all tactical fighter

operations

Page 17: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

Formation FlyingThere are five standard section formations:

The VIC formationThink of the ‘V’ in Vic and invert it.

Formation Technique

Relative speed – Air Speed Indicator (ASI)is the only method of judging speed

Apparent size – using the size of objects to judge distance – 6 miles to 3 miles isn’t obvious,

but 1 mile to ½ mile is.

Distance – Tendency to underestimate, comes with practise & experience

Page 24: AIRCRAFT HANDLING Part 7 Aerobatics and Formation Flying

Formation Technique

Changes are always small & smooth

Longitudinal changes use throttle & elevatorsLateral changes use ailerons

Vertical changes use elevators

A clean aircraft:Accelerates quicklyDecelerates slowly

Acceleration is often poor at low speed in jet aircraft
