ANALOG ↔️ PFD 👩‍✈️👨‍✈️‼️

Until recently, most general aviation aircraft were equipped with individual instruments utilized collectively to safely maneuver the aircraft by instrument reference alone. With the release of the EFD system, the conventional instruments have been replaced by multiple liquid crystal display (LCD) screens. The first screen is installed in front of the left seat pilot position and is referred to as the Primary Flight Display (PFD). The second screen is positioned in approximately the center of the instrument panel and is referred to as the multifunction display (MFD). The pilot can use the MFD to display navigation information (moving maps), aircraft systems information (engine monitoring), or should the need arise, a PFD.

With just these two screens, aircraft designers have been able to declutter instrument panels while increasing safety. This has been accomplished through the utilization of solid-state instruments that have a failure rate far lower than those of conventional analog instrumentation.
However, in the event of electrical failure, the pilot still has emergency instruments as a backup. These instruments either do not require electrical power, or as in the case of many attitude indicators, they are battery equipped.

🛫🛫🛫🛫🛫

Pilots flying under visual flight rules (VFR) maneuver their aircraft by reference to the natural horizon, utilizing specific
reference points on the aircraft. In order to operate the aircraft in other than VFR weather, with no visual reference to the natural horizon, pilots need to develop additional skills. These skills come from the ability to maneuver the aircraft by reference to flight instruments alone. These flight instruments replicate all the same key elements that a VFR pilot utilizes during a normal flight. The natural horizon is replicated on the attitude indicator by the artificial horizon.

🛫🛫🛫🛫🛫

Understanding how each flight instrument operates and what role it plays in controlling the attitude of the aircraft is fundamental in learning attitude instrument flying.

✈️ Aircraft Exterior Lighting System

Retracted during cruise flight

Purpose: Provides powerful illumination while maintaining aerodynamic efficiency.

🔦 Runway Turnoff Lights

Function: Illuminate areas adjacent to the aircraft's forward path.

Location: Near wing roots or nose gear.

Operational Use:

Runway exits
Sharp taxi turns
Airport surface operations

Purpose: Improves situational awareness during nighttime and low-visibility taxi operations.

🟢🔴⚪ Position (Navigation) Lights

Function: Indicate aircraft orientation and direction of travel.

Location:

Red: Left wingtip
Green: Right wingtip
White: Tail

Operational Use:

Night operations
Reduced visibility conditions

Purpose: Enables pilots and controllers to determine an aircraft's relative position and direction.

⚡ Strobe Lights

Function: High-intensity flashing anti-collision lights.

Location: Wingtips and tail section.

Operational Use:

Activated before entering a runway
Remain on throughout flight
Deactivated after runway exit

Purpose: Maximizes aircraft visibility over long distances and helps prevent mid-air collisions.

🔴 Anti-Collision Beacon Lights

Function: Rotating or flashing red warning lights.

Location:
Upper fuselage
Lower fuselage

Operational Use:

Before engine start
During taxi
Throughout flight
Until engine shutdown

Purpose: Warns ground personnel that engines are operating or about to operate.

🔦 Wing Inspection Lights

Function: Illuminate wing leading edges and upper wing surfaces.

Location: Fuselage sides adjacent to the wings.

Operational Use:

Night operations
Icing condition assessments

Purpose: Allows flight crews to visually inspect wing surfaces for contamination, damage, or ice accumulation.

🔦 Logo Lights

Function: Illuminate the vertical stabilizer and airline tail logo.

Location: Horizontal stabilizer or tail-mounted fixtures.

Operational Use:

Night operations
Ground display

Purpose: Improves aircraft visibility while enhancing airline identification.

✈️ Why Aircraft Exterior Lights Matter

Aircraft lighting systems are more than just illumination devices—they are critical safety systems that:

✔ Improve visibility during all phases of flight
✔ Enhance situational awareness for pilots and controllers
✔ Prevent ground and airborne collisions
✔ Support safe airport surface operations
✔ Enable aircraft recognition in low-light environments

Proper use of exterior lighting significantly contributes to operational safety and compliance with international aviation regulations.

Fly-Over and Fly-By Waypoints (IFR) ‼️👨‍✈️👩‍✈️

Waypoints are predetermined geographical locations that are defined in terms of latitude/longitude coordinates or fixes, used to define an Area Navigation (RNAV) route or the flight path of an aircraft employing RNAV.

🛫🛫🛫🛫🛫

Waypoints may be a simple named point in space or may be associated with existing Navigational Aids (NAVAIDs), intersections, or fixes. A waypoint is most often used to indicate a change in direction, speed, or altitude along the desired path. Aviation RNAV procedeures make use of both fly-over and fly-by waypoints. A fly-over waypoint is a waypoint that must be crossed vertically by an aircraft. A fly-by waypoint is a waypoint that marks the intersection of two straight paths, with the transition from one path to another being made by the aircraft using a precisely calculated turn that flies by but does not vertically cross the waypoint.

🛫🛫🛫🛫🛫

Floating Waypoints: Floating waypoints, or reporting points, represent airspace fixes at a point in space not directly associated with a conventional airway. In many cases, they may be established for such purposes as ATC (Air Traffic Control) metering fixes, holding points, RNAV-direct routing, gateway waypoints, STAR (Standard Arrival Route) origination points leaving the en route structure, and SID (Standard Instrument Departure Route) terminating points joining the en route structure.

REJECTED TAKEOFF/ENGINE FAILURE‼️👩‍✈️👨‍✈️

Emergency or abnormal situations can occur during a takeoff that require a pilot to reject the takeoff while still on the runway. Circumstances such as a malfunctioning powerplant, inadequate acceleration, runway incursion, or air traffic conflict may be reasons for a rejected takeoff.

🛫🛫🛫🛫🛫

Prior to takeoff, the pilot should identify a point along the runway at which the airplane should be airborne. If that point is reached and the airplane is not airborne, immediate action should be taken to discontinue the takeoff. Properly planned and executed, the airplane can be stopped on the remaining runway without using extraordinary measures, such as excessive braking that may result in loss of directional control, airplane damage, and/or personal injury.

🛫🛫🛫🛫🛫

In the event a takeoff is rejected, the power is reduced to idle and maximum braking applied while maintaining directional control. If it is necessary to shut down the engine due to a fire, the mixture control should be brought to the idle cutoff position and the magnetos turned off. In all cases, the manufacturer’s emergency procedure should be followed.

🛫🛫🛫🛫🛫

In the event of an engine failure on initial climb-out, the pilot’s first responsibility is to maintain aircraft control. At a climb pitch attitude without power, the airplane is at or near a stalling AOA. At the same time, the pilot may still be holding right rudder. The pilot must immediately lower the nose to prevent a stall while moving the rudder to ensure coordinated flight. Attempting to turn back to the takeoff runway should not be attempted. ❗️Image above illustrates the altitude loss in an event of an engine failure at 300ft AGL❗️The pilot should establish a controlled glide toward a plausible landing area, preferably straight ahead.

✈️ Torque Effect (Engine Reaction)
📌 Propeller rotation creates an equal and opposite reaction on the aircraft
📍 Key ATPL Concepts
✅ Torque Reaction
• Engine turns propeller → aircraft reacts opposite
• Causes rolling tendency around longitudinal axis
➡️ Typical Effect
• For clockwise prop (cockpit view) → aircraft rolls left
• One of the left-turning tendencies
➡️ When strongest
• High power
• Low airspeed
• High angle of attack (e.g. takeoff, climb)
✅ Pilot Correction
• Apply right aileron to counter roll
• Maintain wings level
🧠 Exam Tip (Very Important)
➡️ Torque = roll (NOT yaw)
➡️ Opposite direction of prop rotation
➡️ Most noticeable at high power / low speed
