Thanks for uploading the PDF. Here’s a complete summary of the key information you need to know from the document:

Part 1 – Summary of Important Knowledge

General Aircraft & Flight Basics (PS-28 Cruiser)

  • Aircraft Type: PS-28 Cruiser

  • Category: EASA CS-23 – Light aircraft (used in PPL and early ATPL training)

  • Seats: 2 seats (pilot + passenger)

  • Engine: Rotax 912 ULS2 (piston engine)

📏

Main Aircraft Speeds

Speed Type

Value

Note

VNE (Never Exceed Speed)

138 KIAS

Maximum speed not to be exceeded

VNO (Max Structural Cruise)

108 KIAS

Max speed in turbulent air

VFE (Max Flap Extension)

75 KIAS

Don’t deploy flaps above this

Vr (Rotation Speed)

45 KIAS

Liftoff begins

Vx (Best Angle Climb)

57 KIAS

For obstacle clearance

Vy (Best Rate Climb)

65 KIAS

For fastest climb over time

Vs1 (Stall Clean)

45 KIAS

Stall without flaps

Vso (Stall Landing Conf.)

40 KIAS

Stall with flaps

🧮

Performance Basics

  • Max Takeoff Weight (MTOW): ~600 kg

  • Fuel Capacity: Around 114 liters (usable fuel approx. 100 liters)

  • Endurance: Around 5 hours, depending on power settings

  • Cruise Speed: ~95–100 KIAS

  • Fuel Burn: ~18–20 liters/hour

  • Range: ~400–500 NM with full fuel

📋

Important Procedures

  • Startup Checks – Mixture, throttle, fuel pump, mags, master switch, etc.

  • Takeoff Procedure – Full throttle, maintain runway centerline, rotate at 45 KIAS

  • Climb – Maintain Vy (65 KIAS)

  • Cruise – Set RPM, adjust trim and mixture

  • Landing – Maintain VFE limits for flaps, final approach ~60 KIAS

🚨

Emergency Procedures

  • Engine Failure After Takeoff:

    • Pitch for 60 KIAS

    • Pick safe landing spot

    • Master + fuel OFF before touchdown

  • Engine Fire in Flight:

    • Fuel valve OFF

    • Cabin heat OFF

    • Increase airspeed (blow out fire)

    • Emergency landing

  • Electrical Fire:

    • Master OFF

    • Vents OPEN

    • Use extinguisher

🧠

Operational Limits & Facts

  • Max Demonstrated Crosswind: 12 knots

  • Flaps Settings:

    • T/O = 15°

    • LDG = 30°

  • Oil Temp Range: Keep in limits during climb and descent

  • RPM Limits: Avoid redline, typical cruise is around 5000–5200 RPM

🔍

Radio Navigation (Basics Covered)

  • VHF Range: Line-of-sight limited; keep antenna considerations in mind

  • Transponder: Use correct squawk (7000 VFR), Mode C (altitude reporting)

  • Q Codes:

    • QDM: Magnetic bearing TO the station

    • QDR: Magnetic bearing FROM the station

🧭

Airport Procedures (LERJ – Logroño Airport)

  • Treat as ATC-controlled.

  • Standard circuit:

    • LH (left-hand) pattern

    • Entry via downwind

    • Communication on designated frequency (typically TWR or AFIS depending on airspace)

Summary for Practical Use

If you memorize:

  • Key aircraft speeds

  • Takeoff and landing checklists

  • Emergency procedures

  • Fuel & range data

  • Key radio phrases and navigation basics

  • How to operate in/out of Logroño Airport

Then you’re ready for both exams and practical flight at this phase.
