At 6:03 the controller responds to their intention to climb to FL80 with "Roger" although this is non-standard terminology I would have accepted it to me "Approved" in that part of the world.
My experience with the B737 especially regarding operators in the middle east, apart from close to landing, it is unlikely the F/O would have been following through on the controls, if at all.
The two possible maneuvers were a standard go around:
Initiation:
- Push TO/GA, Flaps 15
- Verify go-around attitude
- Verify or adjust thrust as needed
- Positive rate of climb - Gear Up
Above 400 feet RA:
- Verify LNAV or select roll mode
- Verify missed approach altitude set
- Verify route tracking
Acceleration height:
- Retract flaps on schedule
After planned flaps set:
- Select LVL CHG or VNAV
- Verify climb thrust
- Verify altitude capture
- Do after takeoff checklist
Or a windshear escape maneuver:
- Disconnect Autopilot
- Press either TO/GA switch
- Aggressively apply maximum thrust
- Disconnect Autothrottle
- Simultaneously roll wings level and rotate toward an initial pitch attitude of 15 deg
- Retract speedbrakes
- Follow flight director TO/GA guidance (if available)
- Do not change flap or gear configuration until windshear is no longer a factor
- Monitor vertical speed and altitude
- Do not attempt to regain lost airspeed until windshear is no longer a factor
