T-6A INSTRUMENT NAVIGATION
510. NO GYRO GCA APPROACHES
This type of approach will be introduced to you during intermediates. It is procedurally the same
as the normal GCA approach. You can perform a no gyro ASR or PAR. Since you will have no
EHSI (and perhaps no Electronic Attitude Direction Indicator [EADI]), the controller will vector
you on course by use of the verbiage "Start turn" and "Stop turn." You will be advised to make
SRT until established on final. Continue to make SRT until advised by ATC. Once on final, you
will be advised to make all turns at half standard rate.
Once on GCA final (heading within 10º of runway), stop relaying
all ATC instructions (start turn, stop turn) to the IP, but continue
responding to ATC until advised, "Do not acknowledge further
transmissions". However, clearance to land (option, etc.), direction
to waveoff/go around, traffic calls, and direct questions always
require a response.
Monitor pilot inputs to ensure he complies with instructions and direct IP corrections as
511. MISSED APPROACH
A missed approach is a procedure used to discontinue an instrument approach in the event visual
contact has not been established or the aircraft is not in a position to make a safe landing. Your
primary concern, if unable to land, is to climb to a safe altitude. Therefore, establishing and
maintaining a positive rate of climb should be your first reaction if a missed approach is
commenced. Your second reaction should be to turn the aircraft (if required) to intercept the
missed approach course or to the designated heading. (There may be a mountain dead ahead.)
The approach plate contains a pictorial representation of the missed approach that can be found
in the profile view. The verbiage for the missed approach will be located at the top, right (above
the frequency box). The missed approach will be briefed as part of the Approach Brief and
reviewed between the completion of the Before Landing Checklist and the MAP/DH. Ask your
IP if he requires a missed approach review. The review consists of:
Point at which to execute the missed approach.
First heading to turn.
First climb altitude.
Missed approach prior to the FAF
1. If executing a LOC (ILS/LOC) approach and full-scale deflection of the CDI occurs prior
to FAF, do not descend below the FAF altitude, inform ATC, and follow ATC instructions.
