General Notes

Rudder control: In both Mouselook and External view, Rudder is controlled by clicking and holding the left mouse button, together with left/right stick input (arrow keys or a/d). In external view, Shift + left/right input controls rudder as well.

Stalls/spins: The aircraft is optimized for stall/spin training and VFR flight. In case of low RPM or engine failure, the autofeather system will activate. This will reduce drag and enable the aircraft to glide for an emergency landing (see relevant section below).

Mouselook flight: This aircraft was designed to be flown in Mouselook using the instruments on the dashboard. If you prefer to fly from the external camera view, the HUD will provide you with the main flight instruments.

Checklists: Use the provided checklists to become familiar with normal procedures.

Personalization: The emphasis on this aircraft is primarily on its flight behavior and less on appearance. There is no paint kit option at present. However, parts of the aircraft can be painted in RGB colors using the color HUD provided. The aircraft is modifiable, so additional links may be added (e.g. decals) to further personalize it. The default version already includes some optional decals (aft left and on the tail). You may replace the textures with your own, turn them transparent, or unlink them at will (reset all scripts after each link/unlink operation).

Modifications: Please do NOT rescale the aircraft, NOR modify the names or description fields of existing links, or it will break. Do NOT remove any existing links. Make sure any additional links you add have unique names, different to the ones of already present links. There is a simple way to swap between passenger and cargo variants without the need to unlink (see chat commands below). Reset all scripts after any linking/unlinking.

Systems/Avionics

Dashboard instruments

FMS & Instrument Flight

The T-700 v1.3 includes a simplified flight management system (FMS) allowing for flight route programming and waypoint tracking, linked to the horizontal situation indicator (HSI) and the distance measuring (DME) instrument. In addition to serving as a heading indicator, the HSI allows tracking ILS localizers and GPS fixes and, furthermore, turns into a course deviation and glideslope indicator for ILS approaches. As for v1.4, the FMS can be coupled to servos (see the Autopilot section below). However, even with servos uncoupled, the system provides navigational aid and can be a significant help for approaches.

The figure displays the three modes of the HSI: heading indicator (left), RMI/waypoint direction (middle), and ILS (right).

Autopilot

Autopilot dashboard

The T-700 v1.4 is equipped with functional Autopilot (AP) servos. The AP panel is located on the dashboard (as in the picture) and displays the various active/inactive modes, as well as the heading (HDG), vertical speed (VS) and altitude (ALT) programmed. When the AP is active (servos coupled), the aircraft's ailerons and elevators will receive input according to the selected AP mode. The various modes and their functionality are discussed below.

Fueling

The T-700 currently supports 2 options for fueling:

Annunciator panel & Failures

The T-700 annunciator panel contains six (6) warning lights, as shown in the legend below:

Flight Characteristics & Notes

Normal Operations

In addition to the following notes, use the checklist to ensure proper aircraft configuration for the various stages.

Normal Takeoff

  • Check your lineup using the HSI compass. Check flaps extended. Set takeoff power to 90-100% throttle. Monitor airspeed and rotate at or above 30 knots. Gently raise the nose to +5 degrees pitch, then gradually to around +10 or +15 degrees pitch.

  • Upon establishing a positive rate of climb (vertical speed above 500 fpm), raise the landing gear. Retract flaps above 35 knots. Set climb power to around 65-70%. Monitor airspeed and adjust pitch and throttle accordingly.

Normal Approach (Visual Straight-in)

  • Start at throttle 55%, wings level, gear down, flaps extended, at an initial altitude of 50-70 meters AGL (above runway elevation).

  • Line up early. About one sim before the runway, enter the glide path (i.e. start descent on final approach). Reduce throttle to 40-45%, as required. Aim for the runway numbers (or a little before), i.e. bring the runway numbers just above the bottom of the glare-shield. Your approach should be at a slight nose down attitude, and around 30 knots. Excessive negative pitch will considerably increase airspeed, so power down accordingly and attempt to establish a stabilized approach (constant pitch, constant power setting, constant airspeed).

  • The optimal glideslope for this aircraft is around 8 degrees. If you are too steep, you will have excess airspeed that will be harder to bleed off and might balloon later on and have a "long landing". If you are too shallow, you might stall on flare. Remember: high and fast is better than low and slow. If you think you aren't coming in correctly for the approach, wave off and try it again - no shame in that.

  • If you are correctly stabilized for approach, you will normally NOT need to cut power for landing (that is, if your airspeed on final approach is stable at around 30 knots). If you drop power under those conditions, cutting power completely may result in sudden loss of altitude (and if you pull up suddenly or too hard, you might stall it). If you are at the correct airspeed but too high, drop power slightly and only for as long as needed. If you are below glideslope, consider adding some power for a bit and adjust as needed. If you are descending too fast, reduce power and slightly lift the nose. If you are too too slow, add power slightly and slightly lower the nose. But aim to be around 40-50% power during final.

  • Adjust pitch in order to keep aiming for the runway numbers. If all goes well you will reach the runway threshold at a height of about 20-30 feet (~10 meters). If needed, cut power to 40-45% throttle, and start your flare, i.e. gently pull the nose up slightly above the horizon around 2.5 to 5 degrees of pitch, and keep it there. This will reduce your vertical speed, and bleed off some airspeed so that the aircraft will touch down on its own, with its mean gear first. Avoid nose first landings, as you can be pretty sure it would rip off the nose gear, break the propeller, and cause structural damage to the aircraft. If your descent rate is too big, you can reduce some of the vertical speed and soften your touchdown if you slightly add some power during the flare, just before touchdown - however, adding too much may balloon it or lead to a long landing, so avoid adding power just prior to touchdown if your airspeed is more than 30 knots.

  • If you're slightly high and your flare balloons it, cut some more power down to 40% or even 35% for a short amount of time, as required.

Emergency Procedures

The T-700 does not have a random failures option, but failures can occur as a result of the pilot's actions. Those can be turned off by the chat command input "failures". The most common failures are either due to incorrect fuel being fed into the tank, due to exceeding engine ITT during flight, or due to hot-starting the engine. The warning/annunciator lights will give an indication of the failure and give the pilot the chance to hopefully land the aircraft in time.

In case of engine failure during flight, the recommended procedure (assuming you have sufficient altitude) is:
