Touch and go

[jaguara5]

Does anyone know how IRL the touch and go pattern exactly flown is?

TOUCH AND GO

 

1-Throttle - MAX.

2-Airbrake – RETRACT AS THROTTLE IS ADVANCED.

3-With positive rate and altimeter:

• Gear – UP (Minimum 120 Kts)
  
• Flaps – UP ( Minimum 125 Kts)
  
• Spotlights – UP
  

4-Check correct indications for:

• Gear.
  
• Flap.
  
• Airbrake.
  
• Engine instruments.
  
• Hydraulic.
  
• Electric and fuel.
  

Visual traffic pattern of the airport in question.

Traffic pattern at San Javier Air Base is at 1500’

Speed 150 kts. On downwind, flaps takeoff and gear down. When turning to final, flaps down, make a descending turn to final. Reduce to final approach speed.

Thx! At what speed and altitued should i start turning to downwind?

At what speed and altitude should i start turning to downwind?

 

TL;DR:

 

IMHO the most likely procedure would be to follow the runway heading and climb to 1,000 ft before starting your turn but that's only a guess.

 

According to Vibora's previous post, you are limited in the traffic pattern to 150 kts (best climb speed is ~200 kts at SL, see Vibora's Climb and Cruise .pdf)

 

Detail:

 

Speculation on my part, corrected by Vibora's post below.

 

 

I'm not sure, the 'current' San Javier Chart shows conventional (VFR ?) traffic had a pattern altitude @ 1,000 ft on the NW side of airfield and Jets at 1,500 ft on the SE side.

 

 

RWY 05L / 23R was exclusively for military (Training School ?) use and in the "conventional aircraft" sector.

 

RWY 05R / 23L was used by both by jets and general / civilian aviation traffic i.e. low cost airlines, Diamond DA-40, etc.

 

You would climb to 1,500 ft (pattern altitude) to maintain vertical separation or follow ATC's instructions, it's not clear when you'd start to turn after a "Touch & Go" if staying in the pattern (some missed approaches start their turns after DME 2 NMI, SIDs are at/above 2,000ft by 5 NMI) or if you'd be directed back to a "Holding Point" at Cape Palos.

 

IMHO the most likely would be to follow the runway heading and climb to 1,000 ft before starting your turn but that's only a guess.

AFAIK San Javier closed to civilian operations on 14 January 2019

Tidy up description, San Javier closed on 14 Jan 2019.

At San Javier AFB. At about 250-300 ft, start turn to crosswind, acceleranting towards optimum climb speed and keep that speed until you are at 1500 ft, which will happen most likely once you reach downwind, then accelerate to 250 kts.

You shall keep max thrust untill starting the first turn to crosswind after take off, then reduce to MCT during the turn to crosswind or to be set at around 1000 ft.

Once on downwinds and at 250 kts reduce power as needed to keep 250 kts.

Reduce to 200 kts well in advance, as it's the max speed for gear extension. In a short runway maybe you'll need to keep just 200 kts during downwind.
