Hi Everyone

Just found this site while searching for something else heli related, so thought I'd sign up and say hello to some like minded people.

I've just started my PPL in a R22 and have about 6.5 hours now and loving every minute of it. Wish I had done this years ago but still plenty of flying years infront of me.

Can some one point the obvious out and remind me what the FREDAT checks are? I know the first 2, think the third is equipment but the rest has dissappeared into the grey mess! Rolling Eyes

Thanks
Matt

Hi Rookster,

Glad to see you here - best of luck with your training. I am at the end of mine now and have my skills test booked for next Tuesday!

It's FREDATT

Fuel sufficient
Radio - no calls to make
Engine - Warning lights out, RPMs top of the green, T&Ps OK, Carb set
Direction correct
Altitude correct
Trim - in if in the circuit, out in general flight
Transponder - standby if in the circuit, squark 7000 elsewhere (unless given another code).

I now stand back, and wait for someone to correct me - or improve on the answer.


Rgds,


Craig.

Thanks for the reply Craig, its good enough for me! Hopefully have time to memorize it fully for Saturday!? Memory like a sieve when I am up in the air, so much to think about and concentrate on.

Good luck with the skills test, let us know how you get on!

Cheers.

The bad news is that the list of things to remember grows - the good news is that you do actually start to remember them!!

Best of luck. Where are you learning?

Flying out of Thruxton at the moment.

The learning process by osmosis has all ready started, but I can never recall the bits I need when asked!! Rolling Eyes

Welcome Rookster,

My experience of FREDA is much the same as above, but instead of adding "trim" at the end I was taught to use the "F" as Fuel & Frictions (to include the trim). I have heard the "T" used at the end for Transponder though. I suppose there are many variations...

It might be helpful to hear a few more though, always good to learn other people's methods.

I wonder who made up the "FREDA" mnemonic in the first place? I can't say I've seen it in a book, it's just something my instructors passed on during PPL training.

One useful addition my PPL instructors gave me...... "Direction" - check your DI & compass are in agreement..... makes sure you are heading in the direction you believe you are!!!

Other than..... enjoy it - its never too late! And safe flying!

Before start think of TITS...

Tie downs - off

Instruments - quick check that they are reading correctly for the given conditions.

Temperature - for turbines check TGT to see if cranking is required.

Safety - Clear area around the aircraft.


Happy landings. HH

Hi Rookster,

There are loads of things that you have to memorise - I put together a two pager with all the key things that I laminated and carry with me in the aircraft (usually clipped to the back of the map).

MATED BRIEF
M = MET Check TAFs, 214s, 215s, Route brief
A = AIRCRAFT Check Docs, A check, Fuel plan
T = TRAFFIC Notams, ATSUs, Radio aids, squawks, service required.
E = EXERCISE The plan for the flight
D = DUTIES PIC, safety brief, other requirements of pax if any

IN FLIGHT CHECKS (Check Ts and Ps, Warning lights off and carb heat)
Pre and post take off
Before and after departure
On leaving circuit and every turning point
On approach

HELICOPTER VFR
<3000ft AMSL
Surface in Sight
Clear of Cloud
>1500m viz

RATE 1 TURN
Airspeed * 15%

AIS INFO LINE
0500 354802 / 020 8750 3939
www.ais.org.uk

TITS (VOR Setting)
T = Tune frequency
I = Identify the morse code
T = Test the VOR is working correctly
S = Select the radial you are tracking to/from

HATS (Cross Country)
H = Heading
A = Altitude
T = Time
S = Speed

WASP (Recovery Unusual Attitudes)
W = Wings level
A = Attitude level
S = Speed
P = Power


PRACTICE FORCED LANDING (AWFUL MFI SHAM)

A = Autorotation enter immediately
W = Wind turn into wind
F = Field Select one
U = Up Do I want to restart engine (usually NO)
L = Light Landing lights if required

M = Mayday
F = Fuel Turn off touch drill
I = Ignition Turn off touch drill

S = Surplus electrics Turn off
H = Harness/Hatches and brace
A = Additional Mayday info give exact location
M = Master Battery off

Max distance = 90% RRPM and 75Kts (R22)
Glide ratio is 4:1 or 1NM per 1500ft (R22)
Caution - Increase RRPM>97% when at 500ft (R22)

MAXIMUM POSSIBLE DRIFT
MPD = (60/TAS) *Wind Velocity

% OF MPD BASED ON WIND DIRECTION
15% x 0.25
30% x 0.5
45% x 0.7
60% x 0.87
75% x 0.97

So if your Max poss drift is 20 degrees and the wind is 30% off to port your max drift to starboard is 20*0.5 = 10 degrees.

LISTENING SQUAWKS
SOLENT 0011 Monitor 120.225 over sea
Monitor 119.475 over land
GATWICK 0012 Monitor 126.825
LONDON CITY 0012 Monitor 132.700
LUTON 0013 Monitor 129.550
STANSTED 0013 Monitor 120.625
BIRMINGHAM 0010 Monitor 118.050
MANCHESTER 7366 Monitor 118.575
DONCASTER 6170 Monitor 126.225
BELFAST 7045 Monitor 128.500

POWER CHECKS
Fly straight and level at 53 kts

LANDING
>7 Full vertical *clearing*
>6 Hover OGE *confined*
>5 Hover IGE
>=4 Zero/Zero
<4 Running Landing
Allowance of 1 if power check done with Carb heat on

TAKE OFF (using a 1ft hover IGE)
<1 Running takeoff
>1 Cushion creep
>2 Towering takeoff
>3 Full vertical


FREDAT
F = Fuel / Frictions
R = Radio
E = Engine Ts and Ps / Warnings / Carb heat
D = Direction and DI
A = Altitude /Altimeter
T = Trim / Transponder

WATER
W = Wind direction
A = Altimeter
T = Traffic
E = Engine Ts and Ps Carb heat selected
R = Radio

Note - "water" was taught to me by an instructor as an additional mnenomic for use in the circuit.

CLIMB DESCENT
Carb heat
Attitude Power
Power Attitude
Trim Trim

HASELL
H = Height sufficient
A = Airframe no flaps etc
S = Security no loose items
E = Engine Ts and Ps
L = Location suitable for exercise
L = Lookout no traffic

PASSENGER SAFETY BRIEFING
Approaching the helicopter from the front with pilot eye contact
Departing the helicopter to the front
Warn of the danger of the rotors and tail rotor in particular
Consider briefing of rotors on sloping ground
Use of the doors
Use of the seatbelts
Importance of not touching the controls - If feel unstable put hands under your legs
Brace position
Event of engine failure autorotation + running landing
Show where carb heat is in case need to be applied
Radio communication
Feel free to ask questions but NO talking in the hover, hover taxi, on departure or final approach
Warn departure is along the ground, nose down till airspeed sufficient for climb

WARNING LIGHTS (R22)
Oil Indicates loss of engine power or oil pressure.
Check engine tachometer for power loss and pressure gauge
If pressure loss is confirmed LAND IMMEDIATELY

MR Temp / MR Chip / TR Chip
If light accompanied by indication such as noise, vibration or temp rise then LAND IMMEDIATELY.
If there is no other indication than land as soon as practical

Low fuel You have approx 1 gallon remaining which is 5-6 minutes flying time only - LAND

Clutch
If light stays on longer than 7-8 seconds in flight pull the red circuit breaker, reduce power and LAND IMMEDIATELY. Be prepared to enter autorotation if required

Alt Indicates low voltage and possible alternator failure.
Turn off nonessential electrical equipment and switch ALT off and on again after one second to reset over voltage relay.
If light stays on Land as soon as practical
Continued flight could result in loss of tachometer which is very hazardous.

Brake Indicates rotor brake is engaged. Release immediately if in flight or before starting engine.

Starter-on Indicates starter motor is engaged. If light does not go out when ignition is released from start position pull mixture to idle cut off and turn master switch off. Have starter motor serviced.

Gov Off Indicates that the governor is switched off. It should be switched on for flight.

Carbon Monoxide Indicates high Carbon Monoxide. Open nose and door vents. Turn heater off. If signs of CO poisoning (headache, dizziness, drowsiness) then land immediately.

LOSS OF TAIL ROTOR THRUST IN FORWARD FLIGHT
Failure indicated by nose right yaw
Immediately enter autorotation
Maintain at least 70Kts
Roll throttle into overtravel spring and perform autorotation landing.

Note - it may be possible to fly over 70Kts to a better landing site without the tail rotor. Once at the suitable location enter autorotation to land. The reason to roll throttle into overtravel is to ensure that no throttle is applied on the flare which would increase torque on landing.

Alternatively, you can try 10% + 7

Example:
10% of 80 knots = 8
8 + 7 = 15

My FREDATT is pretty much the same as HeliCraig's, with the addition of checking that the next frequency you are likely to need is ready on standby under the Radio heading.

Another nice little one for cross-country flying whenever you have a few seconds of having done nothing is HATS:

Heading
Altitude
Time
Speed

Mine is also similar with an added H,

FREDHATT, with the H standing for harness and hatches secure

All the best with your training and safe flying

10% of 80 knots = 8
8 + 7 = 15


10% + 7 is the one quoted in the books. The instructor that gave me the 15% rule instead insisted that it was more reliable at the lower airspeeds helis work at (he was previously a heli instrument instructor in the military). I tested his calculation at 80kts on the R22 (so 12 degrees instead of 15 degrees) and it was pretty much spot on. You pays your money and takes your choice Smile
