All Meteorology starts with condensation

All Meteorology starts with condensation,

Condensation is water vapour condensing back the liquid water. 

Visibility is greatly reduced due to cloud, Mist, fog etc.  

Plus releases heat and warm the air  and this is the start to all weather on earth.

Condensation in a warn environment,

Warm environment is Air mass moving over New Zealand  from north or Warm Fronts etc.

A warm air in a warm environment means not much movement or stable conditions.

Cloud that is formed tends to be Stratus / layer re type clouds.

Any rain will be widespread drizzle



Condensation in a cold environment,

However warm air in a cold environment is a completely different ballgame 

The warm air created by condensation will tend to rise rapidly creating towering type clouds which can grow into thunderstorms with heavy rain,  hail, lightning, etc… 

Enough towering Cumulus type clouds can create a low pressure area on the Earth’s surface this pressure change causes the wind to flow.

And these low pressure areas can grow into spinning cyclone / storm.

4.82.22 Procedures to be Followed on Receiving an ELT Signal.

4.82.22 State the procedures to be followed on receiving an ELT signal. AIP GEN

On receiving an ELT signal, pilots must report the following information to the nearest ATS unit:

  • aircraft position and time when the signal was first heard;
  • aircraft position and time when the signal was last heard;
  • aircraft position at maximum signal strength; and
  • aircraft level, strength and frequency of emergency signal on 121.5MHz

4.82.20 Operational Testing of an ELT.

4.82.20 State the requirements for the operational testing of an ELT. AIP GEN

Live testing of 406 MHz is NOT permitted unless coordinated with RCCNZ at least two working days prior to the test

ELT transmitter test is authorised ONLY on 121.5 MHz as follows:

  • tests should be no longer than three audio sweeps and NOT exceed 20 seconds; and
  • tests may be conducted on 121.5 MHz only within the time period made up of the first five minutes after each hour. Emergency tests outside this time must be coordinated with both the nearest ATS unit and RCCNZ. Airborne ELT tests are NOT permitted.

4.82.18 Action Required Following the Inadvertent Transmission of an ELT

4.82.18 State the pilot action required following the inadvertent transmission of an ELT. AIP GEN

Inadvertent activation of ELT has occurred on numerous occasions in New Zealand. It can occur as a result of aerobatics, hard landing, or accidental activation during aircraft servicing. To detect an inadvertent activation pilots should:

  • prior to engine shut down at the end of each flight, tune the aircraft receiver to 121.5 MHz and listen for ELT signals; and
  • if an ELT is heard, ensure that their own aircraft’s ELT is not operating. If it is found that it has been activated, switch it off and take the action described in 6.3.2 then switch it off.

Maintenance may be required before an automatic activation unit is returned to the armed position.

Any person detecting the inadvertent activation of an ELT must report the activation immediately to the nearest ATS unit in order that any RCCNZ action commenced as a result of the transmission may be terminated.

4.82.16 Procedures for the Emergency Activation of an ELT.

4.82.16 State the procedures for the emergency activation of an ELT. AIP GEN

The pilot of an aircraft in a distress situation should activate the ELT while still in flight.

To prevent valuable search time being wasted it is imperative that:

  • All ELTs are registered with RCCNZ.
  • Any ELT that is not automatically activated is switched on as soon as possible before or after any emergency and left on until rescued.
  • If the emergency situation is recovered, ATS or RCCNZ is notified first then the ELT is switched off.
  • If the ELT is switched off and ATS or RCCNZ have not been notified as soon as possible, it will be assumed that the aircraft has crashed and search planning and a SAR response will have commenced.
