4331. Video. Aircraft pushback tractor

 

 

An aircraft pushback tractor is a specialized vehicle used to push or tow an aircraft away from a gate or parking bay, allowing it to taxi to the runway without using its own engines. 

These tractors are low-profile, powerful, and maneuverable, connecting to the aircraft's nose landing gear with either a tow bar or a towbarless system

They are crucial for airport ground operations, as large aircraft cannot easily reverse on their own. 

 

 

 

How it works
  • The tractor connects to the aircraft's nose landing gear using a tow bar or a towbarless system.
  • The driver communicates with the pilot via radio to coordinate the pushback.
  • The tractor then pushes the aircraft backward to a point where the pilot can start the engines and begin taxiing to the runway.
  • Tractors can also be used to move aircraft between different locations at an airport, such as to a maintenance hangar. 
  •  
  • ===========================
  •  

    After all servicing activities are finished, aircraft needs to get back on the runway to take off, however, it first needs to reverse itself from the aircraft stand. This is where the pushback tractor comes in.

    A towing hook attaches its one end to the aircraft and the other end to the pushback tractor. The driver receives a go ahead signal from Pilot and begins the pushback operation.

    It pushes the aircraft back and also steers it so that the aircraft ends up in correct position on the taxiway (a connecting pathway between aircraft stand and runway).

    Pilot then gives an okay to disengage signal to the pushback tractor driver at which he unhooks the towing bar and steers the pushback tractor away from the aircraft.

     

    ---------------
    Changi Airport has the aircraft pushback tractor. It is either the tow-bar or towbarless system either to pull or push the aircraft.

    The towbarless system clamps directly onto the aircraft's nose wheel lifting it slightly off the ground for pushback together with the pilot.


    New development includes the electric pushback tractor for lower emissions and quieter operation.

4528. Teleconsultation - swelling in a 6-year-old red-eared slider on both sides

 

 

TELE-CONSULTATION with
Dr Sing Kong Yuen, BVMS (Glasgow)

26 November 2025. 

A 6.5-year-old male red-eared slider has two  bulges in his groins (front of his hind legs meet the plastron) when he is walking on the floor. The bulges disappear when the slider is inside the tank swimming.

The slider is bright, alert and active. He is eating and pooping normally.
The owner does not know how long has this medical condition been present.

Owner asked if they are abscesses or infections.

Video shown.

Differential diagnosis:
1.  Abscesses
2. Neoplasia such as lipomas (fatty tumours)
3. Cysts
4. Hernias - inguinal hernias are very rare in sliders.

Tentative diagnosis:
Inguinal hernia. More tests are needed.

Proper veterinary examination at Toa Payoh Vets is needed. The owner will make an appointment.

A hernia is a protrusion of internal organs or tissue through a defect or tear in the muscle wall.
An INGUINAL HERNIA is a bulge of internal organs through a defect in the muscle wall of the groin showing a bulge or swelling between the plastron and hip area.

26 November 2025:

Hello Dr, I have a 6 year old turtle and recently noticed a swelling on the side of its body towards the rear. The turtle is otherwise active and eating normally. I wanted to ask if this could be an abscess or infection and whether I should bring it in for an examination. Please let me know the earliest available appointment. Thank you.

DR K Y SING'S COMMENTS:

 A hernia is a protrusion of internal organs or tissue through a defect or tear in the muscle wall.

  • A visible bulge or swelling in the inguinal (groin) area, the region where the hind legs meet the shell (plastron).
  • A soft mass that might be more prominent when the turtle is active and potentially less so when resting.
  • Pain, lethargy, or a decrease in appetite if organs become trapped or strangulated.
  • Difficulty with normal bodily functions such as defecation or movement.

Inguinal hernias
are
rare in reptiles like the red-eared slider. If you observe a suspicious lump or swelling near the hind limbs or tail, it is a serious medical condition that requires immediate evaluation by a qualified reptile veterinarian to prevent complications. 
 
Identifying a Potential Hernia
A hernia is a protrusion of internal organs or tissue through a defect or tear in the muscle wall. In red-eared sliders, signs of a potential hernia would include: 
  • A visible bulge or swelling in the inguinal (groin) area, the region where the hind legs meet the shell (plastron).
  • A soft mass that might be more prominent when the turtle is active and potentially less so when resting.
  • Pain, lethargy, or a decrease in appetite if organs become trapped or strangulated.
  • Difficulty with normal bodily functions such as defecation or movement. 
Importance of Veterinary Care
Due to the unique anatomy of turtles, the protective shell makes both diagnosis and surgery challenging. Diagnostic tools a veterinarian might use include physical examination, palpation (feeling the area), radiographs (X-rays), and ultrasound to determine the contents of the mass. 
 
If a hernia is diagnosed, surgery is the typical treatment to prevent serious complications like a strangulated hernia, where the blood supply to the tissue is cut off. There are specific surgical techniques for chelonians, such as the prefemoral approach (an incision in front of the hind limbs), which require specialized knowledge. 
 
Do not attempt to treat the condition yourself. Use resources like the Association of Reptilian and Amphibian Veterinarians (ARAV) website to find a veterinarian experienced with reptiles.
