T-6A INSTRUMENT NAVIGATION
Consider the above example. When you reach the published DH of 114 feet MSL, you will be at
a HAT of 100 feet AGL. In order not to break the 200-foot HAT absolute minimum, you must
increase the DH. In this case, an increase of 100 feet is necessary. This would result in a
modified DH of 214 feet MSL resulting in a HAT of 200 feet AGL. Also, do not forget to
compare the VIS.
Initial Contact. You will make the request for GCA approaches upon initial contact with
approach control. The following approach information will be provided by ATC to aircraft
conducting radar approaches:
Type of approach. "This will be a PAR approach to runway 5."
3. Ceiling and visibility if below 1000 feet (or below highest circling minimum, whichever is
greater) or visibility less than three miles.
Special weather observations.
Airport conditions important to the safe operation of aircraft.
6. Lost communication procedures and missed approach procedures/climb out instructions,
when weather reports indicate IFR weather conditions are likely to be encountered during the
approach. Lost communication instructions will typically include an altitude and a standard IAP.
Missed approach procedures will be issued to an aircraft planning a full stop landing.
Climb out instructions will be issued for aircraft planning anything other than a full stop.
Example of Lost Communications: "KATT 603, if no transmissions received for 30 seconds in
the pattern or 5 seconds on final, attempt to contact Tower on 340.2 and proceed VFR. If unable
to proceed VFR, proceed to CHAPE and execute the RNAV 1 approach, maintain 2200 until the
Example of Missed Approach / Climb Out Instructions: "KATT 603, on climbout, fly runway
heading, maintain 800 feet until 2.0 DME past the TACAN. Then turn right to 180, climb and
maintain 1500 feet".
Unless specifically requested, approach controllers in Pensacola
will only provide missed approach and lost communications
procedures if IMC are present at the field or likely to be
encountered on the approach. If these instructions have not been
received prior to handoff to the final controller, ask the IP if they
are required. If required, request them from ATC.
