Two operators are recommended to operate the system. Generally, a pilot in command, who is responsible for all flight operations and a co-pilot to assist with ground control operations, mission planning and camera/payloads control.
The ALTI Transition can be rapidly deployed from in the case to in the air in approximately 10 min. This includes unpacking, assembly, mission planning, fueling and conducting all the preflight checks.
ALTI uses Volkswagen’s Transporter Crew Bus Long Wheelbase to transport our products. Any vehicle with a load bay size of 2m (l) x 1,2m (w) x 0.75m (h) will be sufficient to transport the aircraft. The Transition and all the equipment required to operate the aircraft is neatly packed into a rugged hardcase for safe transportation and storage.
Our standard models are sold without Transponders, but we offer a range of ADS-B Transponder that can be installed. We have used and recommend the uAvionics Ping 20Si.
We are busy working with experts in this specific field to develop such a solution for our aircraft, and will be implementing this feature in the near future.
We suggest an area of between 4m to 6m squares. The aircraft takes off and lands vertically so any area larger than the aircraft itself will do, but for safety reasons any larger areas are recommended.
VTOL stands for Vertical take-off and landing. Meaning the aircraft ascends and descends vertically and does not require a runway, bulky launch equipment or parachutes for take-off or landing.
Depending on the actual weather, The ALTI Ascend and Transition aircraft design does not permit operating in wet weather conditions. The ALTI Reach is capable of flight in wet and rainy conditions, depending on payload and other options required.
Search and Rescue
We have flown various payloads and achieved accuracies of between 2 to 4 cm, which are well within accepted industry standards.
Depending on the aircraft, payload and all-up-weight. Hover time is strictly for take-off and landing, with a maximum hover time of up to 3min. Fixed wing flight on the ALTI Ascend is up to 6 hours or 500km (2-4 hours with maximum payload), 12 hours or 900km (6-8 hours with maximum payload) on the ALTI Transition and up to 20 hours or 1800km (8-14 hours with maximum payload) on the ALTI Reach, depending on aircraft options and setup.
Not yet, alternative landing gear incorporating floating devices are being developed for this purpose.
Yes, subject to our technical department conducting a feasibility analysis to check whether the requested modification or upgrade can be made. We also offer advanced custom development and integration services.
Yes, an experienced UAV pilot is required to operate and fly ALTI aircraft. We have minimum operator requirements that can be used as a guideline to safely operate our aircraft.
Our hardware components are rated to handle temperatures between -10° and +50°.
Our aircraft has been CFD tested to operate at a maximum altitude of 4000m ASL, density altitude.
Each specific application will dictate the optimal height of operation, but most clients operate between 120m to 500m AGL.
The aircraft has various autonomous failsafe features that allow for safe operations in all flight modes. In the event of a main engine failure, the Autopilot will detect the drop in airspeed and initiate the VTOL motors to immediately regain safe hover flight before the aircraft stalls.
The operator must glide the aircraft in for an emergency landing. Please do note that we have never, not once, had any VTOL motor failure on any ALTI aircraft, in development, test flights or client production aircraft. We make use of the highest possible quality VTOL motors and controllers and have specifically designed the system to be simple and highly reliable.
Aircraft telemetry data and payload video typically uses 2.4GHz, and the control link is 868MHz or 915MHz (country specific).
Yes, with optional advanced radio systems mesh networking is possible.
Yes, the video feed is digital (IP based) and can be streamed over an internet connection or local network.
Yes, the data can be sent to more than one location via the internet or local network (wired or wireless).
Not as standard but different encryption options are available.
Yes, the digital video link can be integrated into most 3rd party applications or software programs.
After 30 seconds (adjustable) of data link signal loss the aircraft will go into an automatic Return-to-Land (RTL) mode.
After 1.5 seconds (adjustable) of control link signal loss, the aircraft will go into an automatic circle or loiter mode to regain connection. If after 30 seconds (adjustable) the link has not been re-established, the Return-to-Land (RTL) mode will be initiated.
For added redundancy and frequency allocation. Lower frequencies allow for a more stable and reliable connection and further range.
Yes. The data link can be used to control the aircraft (Guided mode, auto mission flight etc), meaning there is no direct input from the operator only flight instructions to a set point can be made.
Our aircraft are able to fly in a variety of wind conditions.
20m/s ( 75kmh / 40kts )
Wind Resistance (Take-off)
10m/s ( 36kmh / 20kts)
Wind Resistance (Cruise)
15m/s ( 54kmh / 30kts )
Our products are exported to various countries across the world. We work with each client to make sure their local import rules, regulations and requirements are adhered to.
Yes, we have various EO/IR options available. We suggest the Trillium HD 25, HD40 and the NextVision NightHawk2.
Yes, Object or Scene Tracking, along with more advanced GEO-lock features are available.
Only payloads that fall within the weight restriction, size dimensions and power supply specifications of the Transition can be integrated.
For directly piloted control as a pilot, direct line of sight is required. Flight control is via the remote controller connected to the GCS. Normal autonomous mission flight is done via the autopilot and a planned mission stored on the aircraft and no manual pilot control, or line of sight is required.
All data and video footage can be recorded and stored directly on the Ground Control Station’s Hard drive and can be viewed or transferred to another storage device. Some payload also offers on-board recording.
The aircraft needs to maintain a link with the GCS for safe and legal operation. This will only be achieved with clear Line of Sight from the GCS to the aircraft. The maximum range will be determined by your choice of antenna solution and the environment, altitude and location of flight. Link range with the standard ALTI Ground Control System is up to 10km. We also offer various more advanced and higher-powered radio system and tracking antennas with maximum ranges of up to 150km.
No, the GCS can be operated with batteries. It has a smart power management system that can switch between available power sources without losing power. Batteries can also be hot-swapped during operation for pro-longed operation without powering the GCS down.
Service & Support
Yes, the autopilot stores all flight telemetry data for each flight. This data can be viewed by the operator or sent to ALTI Support for post-flight analysis or preemptive support services.
Currently all support and communication in provided in English. Translation services can be arranged.
ALTI provides free full technical support (via email or telephonically) to all our clients.
Yes, we offer key spares for maintenance when purchasing a ready to fly aircraft.
Yes, we do offer full system training for ALTI aircraft. Please note this is not pilot or flight training and only systems familiarization training on ALTI aircraft.
Training is conducted at ALTI in Knysna, South Africa. We can offer location specific (international) training pending availability.
