PPL/CPL ground aircraft performance (152, change for other aircraft types)

What type of engine does your aircraft have?

CHECK POH AND ADD FOR 152

What type of fuel is required

100LL aviation fuel if available or 100 grade aviation fuel

What is the total useable/ unusable fuel

Total usable is 24.5 USG, unusable is 1.5 USG total capacity is 26 USG, split into 2 tanks

If the fuel vent became blocked what could happen

You could have fuel starvation occurring causing the engine to stop

What is the minimum and maximum oil capacity

Minimum is 4 quarts with a max of 6

Does the aircraft have a fuel pump

No it does not the fuel is gravity fed

Describe/draw fuel system fo the aircraft

Use POH

What type of fluid does the nose oleo require and the brakes

Nose oleo requires MIL-5606 hydraulic fluid and the brakes use DOT-4

What is the recommended tire pressure for the mains and nose wheels

21 PSI for the mains and 30 PSI for the nose wheel

What is the electrical system voltage

28 volts

What is the voltage of the battery

24 volt battery

How many amps does the alternator generate

Belt driven generating 60 amps

How does the ammeter work

Indicates if the battery is charging (right indication) fully charged (neutral indication) or battery overload/alternator failure (left indication)

What does the red voltage light indicate

Over or undercharging, if undercharging may be a annunciation

How does total electrical failure affect the mags

Will not be affected

What would you do if the ammeter has right deflection and the voltage light is on

I would land ASAP knowing if the voltage sensor is malfunctioning i would turn the alternator off as well as nonessential electrical equipment

What would you do if the ammeter had left deflection and the voltage light was on

I would land ASAP and after turning the master off and then back on if it is still failing i would shut off all non essential avionics to save battery power for flaps

What type of flaps does your aircraft have

CHECK POH

What type of ailerons does your aircraft have

CHECK POH

Does your aircraft use an elevator, stabilator or anti servo tab?

Elevator with trim tab yes, all others no

Does the trim tab move in the same direction as the elevator, stabilator or anti-servo tab

Opposite for all but the anti servo tab

Name the pitot static instruments

VSI< altimeter, and airspeed indicator

Which pitotstatic instruments use the pitot tube and static port

Airspeed indicator used the pitot tube and all 3 use the static port

What occurs with a pitot tube blockage? Static port blockage?

Pitot tube:

Airspeed indicator is affected

Static port

All 3 affected, fixed by using alternate static source of breaking the glass on the VSI

Name the gyro instruments and explain how they are powered

attitude indicator is vacuum driven as is the heading indicator

How to determine if gyro instruments have reliable info

Suction gauge is green, no flags, instrument check on taxi and attitude indicator giving proper info within 5 mins of startup

Name the major sources of error in the heading indicator

Bearing friction and earths rotation

How often must you reset the headlining indicator and when can you set it

It must be reset every 15 minutes and can only be set in straight and level or stabilized climbs/descents

How does the inclinometer work

It works on the principle of gravity

Does the turn coordinator indicate the amount of bank

No it indicates the rate of turn and roll

How to lean the mixture for best cruiser and best power

Use max range/endurance of follow POH guidelines

What is the danger of running the engine to lean

May cause overheating/detonation

Whats happening if oil pressure drops and temps rise and what can you expect

Indicates engine problems and a possible engine failure

Quote te following speeds from memory

Vx: 55

Vy: 67

Vs: POH

Vso: POH

VA

Weight 1: 104

Weight 2: 98

Weight 3: 93

Vno:

Vne:

Best glide: 60

Define Va and explain why it is important

It is maneuvering speed and is the max speed at which the airplane is not being overstressed at full deflection

What happens to the Va with an increase in weight and why

Va increases with a increase in weight because with more weight there aircraft will stall before obtaining structural damage with the stall itself preventing any damage from occurring

What is the definition and significance of Vno

It’s the max structural cruise speed where operations are only permitted with caution and in smooth air

Define Vfe

Vfe is the max speed permitted with flaps extended

How does weight affect stall speed

Increasing the weight also increase the stall speed, as an aircraft with more weight requiring a higher AoA to produce the same amount of lift meaning that aircraft will stall at a higher airspeed

How does bank affect stall speed

The greater the bank angle the higher the stall speed

In a climbing turn which wing will stall first

The higher wing will stall first

In a descending turn which wing will stall first

The lower wing will stall first

Why do we not use ailerons for wing drop during a stall

If we have a stall the ailerons become ineffective and trying to pick up a stalled wing with aileron will make the stall worse

What is the max crosswind component and what does it mean

It means the max cross wind the aircraft was tested to and it s 12 kts

What is the significance of the speed providing the best lift to drag ratio

It equals your best glide speed allowing you to travel the longest distance per unit of altitude lost

Whats the difference between a forward side and a side slip

A forward side slip is used t lose altitude without reducing airspeed, in a forward side the longitudinal axis is parallel with the runway

In a side slip does the ASI over or under read

It depends on which side the static port is on, can be dangerous so side slip with extra speed to not stall

Why do we retract the flaps during a short field landing on the ground roll

We are changing the wing camber to produce less lift and add more weight to the wheels to make the brakes more effective

According to the POH at which altitude must you recover from a spin

To do it where you can recover by 4000 feet, and the flight test guide says 2000 or above

How do you recover from a spin

Neutralize ailerons, power idle, opposite rudder, nose down, ease out of dive

Can you spin the aircraft if it is in the normal category

No you cannot

What is the danger of having flaps down in a spin

They induce flatter spins and during recovery Vfe speed will be exceeded by a wide margin

What would you do if you inadvertently flew into icing

Turn back or change altitude an set up throttle for use carb heat with max power

What to do if you have a full comms failure in flight

Squawk 7600, try to contact tower on cell if in zone, leave zone by shortest route possible

What is the significance of the yellow arc

It shows you the region where maneuvers must be done with caution only in smooth air

During run up the oil pressure gauge is inoperative can you continue

No, MOOFACTA
