From density altitude and deteriorating weather to flight planning and search-and-rescue procedures, a recent aviation safety briefing at Brakpan-Benoni Airfield revisited some of general aviation's most familiar risks.
Aircraft performance, weather, fuel management and flight planning are fundamental parts of pilot training. Yet failures involving these familiar subjects continue to feature in serious and fatal aviation accidents.
These are not new or poorly understood hazards. Pilots are introduced to them early in their training, and the procedures and information needed to manage them are readily available. Nevertheless, mistakes continue to occur, raising questions about how consistently the fundamentals are applied in everyday flying.
These concerns featured prominently during a safety briefing hosted by Alt. Academy at Brakpan-Benoni Airfield (FABB) on 7 November 2026. The event brought together student pilots, experienced aviators, search-and-rescue specialists and aviation support organisations to discuss some of the recurring challenges in general aviation.
Santjie White, former Chief of the Aeronautical Rescue Coordination Centre (ARCC), addressed complacency in a short interview following the briefing.
“The most important thing is not to become complacent, to plan and plan again.”
White also emphasised that preparation extends beyond the aircraft itself. A pilot's mental wellbeing, proficiency and readiness for the intended flight deserve the same consideration as the aircraft's serviceability.
Density Altitude and Aircraft Performance
For pilots operating from South Africa's Highveld airfields, density altitude is an everyday consideration, particularly during the warmer summer months.
As density altitude increases, aircraft performance deteriorates. Take-off distances increase, climb performance decreases and an aircraft may not perform as it did under cooler conditions.
These effects are well established and are covered extensively during flight training. However, familiarity with an airfield or aircraft does not guarantee the same performance on every flight.
Aircraft loading, temperature, wind, runway conditions and elevation all influence the available performance. A runway that provided adequate margins on a previous flight may present different limitations under changed conditions.
The aircraft's approved performance documentation provides the information needed to assess these factors. Previous experience with an aircraft cannot replace calculations based on the conditions of the intended flight.
Weather and the Pressure to Continue
Deteriorating weather remains a significant concern in general aviation, particularly when pilots face pressure to complete a flight.
Alt. Academy CEO Ryan van Wijk shared several experiences from his flying career, including challenging weather encounters and a flight involving a pressurised Baron.
Retired South African Air Force Colonel Keith Fryer also discussed the influence of passenger expectations on pilot decision-making, particularly among less experienced aviators.
Commercial commitments, accommodation bookings and passenger expectations can all create pressure to continue when conditions are no longer favourable.
Weather planning extends beyond checking the conditions at departure. Conditions along the route, at the destination and at suitable alternates must also be considered, particularly on longer cross-country flights.
Inadvertent VFR flight into instrument meteorological conditions (IMC) remains a recognised accident risk. A developing weather problem may leave a pilot with progressively fewer options, particularly when decisions to divert or discontinue a flight are delayed.
Both Van Wijk and Fryer drew on personal experience to discuss the importance of recognising changing circumstances and making decisions before available alternatives become limited.
Flight Plans and Search-and-Rescue Preparedness
A flight plan provides more than routing information. It can also give search-and-rescue coordinators an important starting point when an aircraft fails to arrive.
Gregory Critchley, Chief of South Africa's ARCC, explained some of the difficulties encountered when aircraft go missing and reliable information is unavailable.
Among the concerns raised were flight plans that had not been properly activated, emergency contact details that were no longer current and aircraft that had become overdue without anyone recognising their absence.
The South African Aeronautical Information Publication (AIP) sets out the procedures for activating and cancelling nominated search-and-rescue services.
Pilots need to understand these procedures, particularly the distinction between filing a flight plan and activating the associated SAR service.
Prematurely cancelling SAR protection can leave an aircraft without that nominated protection during the remaining flight. Equally, failing to cancel it after a safe arrival can result in unnecessary follow-up action.
Critchley also raised the importance of reliable emergency contact details. An office telephone number that goes unanswered outside working hours may delay attempts to establish an aircraft's whereabouts.
For flying schools and operators, aircraft-return monitoring is another consideration. Knowing when aircraft are expected back, and having a reliable procedure for recognising overdue flights, provides an additional safeguard when something goes wrong.
Know Who to Contact in an Emergency
The ARCC coordinates aeronautical search-and-rescue operations in South Africa and its designated search-and-rescue region.
In a separate interview after the briefing, Critchley emphasised a straightforward precaution: pilots and their families should save the ARCC's emergency contact numbers in their mobile phones.
Its published contact numbers are:
ARCC 24-hour duty: 063 505 4164
ARCC standby: 063 505 5485
Following an accident or forced landing, accurate information about an aircraft's position, registration, occupants, injuries and accessibility can assist rescue coordinators in organising an appropriate response.
Critchley discussed the difficulties caused by delayed notifications and attempts to organise independent rescue efforts without involving the ARCC. The organisation works with various emergency services and volunteer agencies to coordinate rescue operations.
Pilots and operators should also distinguish between requesting emergency assistance and meeting formal accident or incident notification requirements.
South African Civil Aviation Regulations set out the requirements for reporting aircraft accidents and incidents, including notification procedures, responsibilities and applicable time limits. Pilots and operators should familiarise themselves with these requirements and consult the current regulations available through the SACAA portal.
The briefing also addressed the circulation of accident-scene photographs, particularly where families may learn of an accident through social media before receiving an official notification.
The Human Factors Behind Aviation Safety
The effects of an aviation incident are not necessarily limited to physical injuries or aircraft damage.
Representatives of Mayday-SA discussed the psychological pressures experienced by aviation professionals, including the consequences of accidents, professional difficulties and concerns relating to medical certification.
The organisation provides confidential, peer-based support to pilots, air traffic controllers, engineers, cabin crew and other aviation professionals.
Its network includes volunteers familiar with the aviation environment, with access to professional support where necessary.

The briefing also addressed the value of sharing experiences, particularly difficult decisions and near misses.
For student pilots, these accounts offer insight into situations that may not arise during routine training. They also provide an opportunity to understand how experienced aviators recognise developing problems and assess their options.
The discussions at Brakpan returned repeatedly to subjects taught from the beginning of pilot training. The procedures are familiar, but their application still requires attention on every flight, regardless of a pilot's experience or the apparent simplicity of the operation.
