Note the "FAF to MAP" timing at the bottom of the airport sketch. This table is used to

determine the time to the missed approach point from the Final Approach Fix at various ground

speeds. Ground speed must be estimated. Example: With an approach speed of 120k and 15k

of headwind, ground speed becomes 105k with timing (Figure 7) of 3:30.

LOW ALTITUDE INSTRUMENT APPROACHES

Introduction - An instrument approach enables an aircraft to transition from instrument flight

conditions to a visual landing while providing terrain clearance and separation from other

aircraft. There are a number of low altitude instrument approach procedures which may be

executed with the navigation equipment in the T-34C. These include procedure turn, teardrop,

holding pattern, straight-in, and arc and radial combination approaches which use VOR, DME,

TACAN or a combination thereof to define the approach. Radar vectors to final approach course

is an additional procedure which may be applied to any of the above approaches.

Procedure

1. Prior to departure familiarize yourself with the destination instrument approach

procedures (IAP's) compatible with aircraft navigational aids. Check forecast weather

conditions against weather minimums listed on the approach plate and choose a suitable

alternate. Enroute, review the approach procedures and check the destination ATIS.

2. Determine whether the duty runway requires straight-in or circling minimums, then

compare current weather and the weather minimums for the approach. The T34-C is considered a

single-piloted aircraft. Therefore, you may not commence an instrument approach if either
