Before every flight, pilots have a legal obligation to ensure the safe conduct of the operation. It’s essential to establish a thorough pre-flight planning process, which should include verifying the validity of your personal license, assessing aircraft serviceability, and reviewing the latest weather and NOTAMs.
As the pilot in command, it is crucial to evaluate your own fitness to fly. This assessment encompasses both physical and mental well-being, as well as your proficiency and currency for the planned flight.
Prior to in-depth planning for a specific destination, conduct an initial review of the weather and NOTAMs to identify any immediate concerns, such as adverse weather conditions or training restrictions.
If your flight involves multiple aerodromes, make sure to check the NOTAMs and weather conditions for each location you intend to visit.
Lastly, conduct your flight planning in a quiet, distraction-free environment. If it has been some time since your last flight, allocate extra time to refresh your knowledge of necessary procedures and items that need to be checked.
Dento Aviation promotes a 'Threat and Error Management' (TEM) approach to flight planning and execution. TEM focuses on the timely identification of threats, errors, or undesired aircraft states, and involves implementing appropriate responses to ensure safe flight operations.
Threats may include unpredictable weather or complex airspace scenarios. It is essential to consider how to mitigate these risks. Additionally, potential errors during flight execution—such as incorrect aircraft configuration or navigation issues—should also be acknowledged. Employing a systematic approach throughout the various stages of the flight and utilizing checklists can significantly reduce the likelihood of errors.
Pilots must assess that cloud base and visibility conditions are suitable for the intended flight. Safe minimum visibility standards can vary based on factors like terrain and obstacle elevation.
Flying below 1,500 feet AGL is not recommended, as it can complicate visual navigation, decrease terrain clearance, and heighten the risk of encountering obstacles such as tall masts.
In addition to reviewing the weather at the departure and destination aerodromes, develop an understanding of the en-route weather conditions. Analyze TAFs and METARs for airports along your flight path, keeping in mind elevation differences when evaluating reported cloud levels.
Training flights will only proceed if weather conditions satisfy VFR minima as outlined in the AIP. No training flights will be conducted in significant weather conditions that pose a risk to flight safety. However, “basic instrument flight” training may occur under IFR conditions, provided both the Flight Instructor and the aircraft are appropriately certified.
All operations must remain within the operational limits of the training aircraft as stated in the pilot's operating handbook.
When establishing weather limits, it is vital to consider the experience level of each individual applicant. The following table serves as a guide:
VISIBILITY: 8 KM
DISTANCE FROM CLOUD: 2.000ft Vertical / 3.000m Horizontal and In-Sight of the surface
VISIBLE HORIZON: YES
X-WIND: 7KTS
H-WIND:15 KTS
VISIBILITY: 5 KM
DISTANCE FROM CLOUD: 1.000ft Vertical / 1.500m Horizontal and In-Sight of the surface
VISIBLE HORIZON: As required
X-WIND: 15 KTS
H-WIND: 25 KTS
You must check NOTAMs before flight. Further details of temporary changes can be found in AIP supplements.
Part-NCO specifies minimum fuel reserves above the amount required to fly the intended route:
Aeroplane reserves are computed at ‘normal cruising altitude’ and for helicopters ‘best range speed’. These should be regarded as minimums for fuel carriage. It is important to know your anticipated fuel burn at different cruise power settings.
It is a legal requirement for the aircraft to remain within its specified weight and balance envelope throughout the entire flight. Ensure that you are familiar with the methods for calculating weight and balance (W&B) for your specific aircraft, and accurately determine the weight of passengers and cargo on board.
Additionally, it is essential to verify your takeoff and landing performance to ensure safe operations.
It is a legal requirement to carry suitable and current navigation charts. While electronic charts are acceptable, the ATO strongly recommends having a paper chart as a backup.
For VFR flights, pilots should make effective use of moving map devices that incorporate current aeronautical data and are integrated into all phases of flight planning and execution.
Additionally, it’s advisable to review and mark the planned route on a 1:500,000 or 1:250,000 scale VFR chart, which serves as both a backup and an additional information resource during your flight preparation.
When evaluating your route, identify potential airspace hazards, high terrain, and other obstacles. Take these factors into account during planning; for instance, if the forecasted cloud base is lower than expected, it may be wise to choose a route that’s further from high ground.
While there is no legal mandate for a formal ‘minimum safe’ altitude during VFR flight, it is prudent to establish personal altitude thresholds for the intended route that you will not descend below. Be sure to have alternative plans in place should weather conditions render the original route unsuitable.
Keep in mind that the ‘Maximum Elevation Figures’ (MEF) displayed on VFR charts represent the highest terrain or obstruction expected in a given area, but do not include a safety margin and should not be considered a minimum safe altitude.
Even when using a moving map display, it’s important to identify significant ground features and/or visual reference points (VRPs) along your route. These may be necessary for ATC coordination when transiting controlled airspace or approaching an aerodrome.
Aim to fly at the highest practical altitude, considering airspace restrictions and aircraft performance. You may also want to select randomized altitudes for your cruise, rather than consistently choosing round numbers.
Creating a Pilot's Log (PLOG), whether electronically or on paper, is highly recommended for each flight. A well-organized PLOG should include:
VFR flight requires that you remain in ‘Visual Meteorological Conditions’ at all times. The assumption of VFR flight is that you have enough visibility to control the aircraft by visual references and avoid collisions with terrain and other aircraft.

(**) The VMC minima in Class A airspace are included for guidance to pilots and do not imply acceptance of VFR flights in Class A airspace.
(***) When so prescribed by the competent authority:
Flight visibilities reduced to not less than 1,500 m may be permitted for flights operating:
(1) at speeds of 140 kts IAS or less to give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or
(2) in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low volume traffic and for aerial work at low levels.
Pilots should maintain a visual scan outside the cockpit approximately 80% of the time, particularly focusing on detecting other aircraft. The ATO encourages the use of Electronic Conspicuity (EC) devices to aid in visually identifying potentially conflicting traffic. It is essential that users understand how to correctly configure these devices and are aware of their individual functions and limitations.
Set the aircraft's flight attitude primarily by visual reference, while occasionally consulting your instruments for confirmation. Before changing altitude or making a turn, conduct a thorough visual scan of the sky in your intended direction. During climbs, periodically perform small lateral turns to check for traffic that may be obscured by the aircraft's nose. In high-wing aircraft, raise the wing before initiating a turn to ensure you can see any traffic to your side or above.
While monitoring your position on the VFR moving map, avoid becoming overly fixated on cockpit instruments. Refrain from "track crawling" or "chasing the magenta line"; instead, maintain a steady heading and periodically assess your track. If a correction is necessary, select a new heading as required.
Use the acronym 'FREDA' as a useful reminder for periodically assessing the status of your flight and aircraft. Conduct these checks at significant route waypoints or approximately every 10 minutes:
Every year, pilots inadvertently transition from visual flight conditions to instrument flight conditions (VFR into IMC), often with tragic outcomes. In fact, VFR into IMC is the leading weather-related cause of accidents, with a staggering fatality rate of 86% in non-commercial fixed-wing aircraft. It is crucial to respect weather limitations and make prompt decisions to divert when conditions are not suitable for safe flight.
Shut-Down and Parking Procedure
At the conclusion of each flight, both students and instructors must follow these procedures:
Note: Foreign Object Debris (FOD) refers to any items found inappropriately on the airfield that could potentially damage equipment or injure personnel.
