Overview

All angle of attack instruments, including the LIFT MONITOR, sense the aircraft's ability to sustain lift regardless of airspeed, pitch angle, G-force acceleration, gross weight, temperature, or barometric pressure. However in addition, the Lift Monitor from Lift Management, LLC is specifically designed as an affordable tool for developing pilot skill and confidence in handling the aircraft you are flying today as opposed to the one you were trained in or recently sold. The intuitive broad spectrum analog display clearly shows lift currently experienced by the aircraft as well as subtle trends to which you can instantly respond.

Calibrate the Lift Monitor based on your own level of comfort with lift available in slow flight. As you gain familiarity and confidence flying with reference to the Lift Monitor, explore your aircraft's response to lower levels of indicated lift, as with slower approach speeds and steeper bank angles. The wing probe can then be easily adjusted in minutes to reflect a tighter margin of available lift at critical angles of attack appropriate to your increasing familiarity with the aircraft's performance capabilities.

By monitoring lift, the pilot can develop the ability to land slower with safety, permitting less wear on tires and brakes. Similarly the demands short field and high density altitude take-offs can be monitored to ensure safe operation within the limits of your aircraft. The Lift Monitor greatly enhances safety during your turn to final approach with a tail wind on base leg and when maneuvering during photo flights as well as in unusual attitudes.

Transition training for a future buyer of your aircraft also becomes far safer with the Lift Monitor. A demonstration flight, including an assessment by the buyer of his comfort level at the current calibration, will indicate whether a five-minute recalibration to a more conservative setting is appropriate in order to provide adequate safety while the buyer's "seat of the pants" undergoes adjustment. The low cost of the Lift Monitor and simplicity of installation leave little excuse for not availing yourself of the safety and performance afforded by an AOA system. And the Lift Monitor is FAA approved for installation on all GA aircraft, not just experimentals. Working completely independently of all other aircraft systems, installation requires only a log book entry on the part of your mechanic.

Lift Monitor models are available as either a panel mount or glare shield installation. Adapters are provided for existing 2/14" and 3-18" instrument holes. A "Remove Before Flight" protective cover for the probe is included with each system.

FAA Approved for all General Aviation Aircraft - Minor Modification with a Log Book Entry.

Specifications

Panel Mount Kit 05-14964: Overall diameter of the gauge bezel is 3-1/16". The Panel Mount Gauge hole diameter is slightly larger than a standard 2-1/4" instrument hole. Kit includes probe cover, 15' of color-coded and bonded polyurethane tubing for easy routing, an adapter plate for gauge installation in an existing 3-1/8" instrument hole, as well as a concentric scribing die to expand an existing 2-1/4" instrument hole for easy installation using 4 instrument screws (not included).

Glare Shield Mount Kit 05-14966: Overall diameter of the gauge bezel is 3-1/16". Hose barbs for the air line connections extend downward for a clean looking installation. Includes probe cover, 15' of color-coded and bonded polyurethane tubing for easy routing, an anodized aluminum mounting bracket, brass instrument screws, and aluminum locknuts.

Installed on my Zodiac 601HD. Easiest of all AOA to see. Precise analog display avoids the changing colors of lights. Strongly recommended!

After flying an Ekolot Topaz with this Lift Monitor installed I plan on having one in any aircraft I own in the future! It is simple and straight forward to install and calibrate. The instrument is intuitive on how close to a stalled condition you are. A great tool to fly with!!

Simple design, low cost, valuable instrument. Wouldnt fly without mine. Land with confident air speed repeatedly.

Q&A

Q: Does your AOA have a flap compensator or can one be added?

Per the manufacturer - To answer your question, no it does not have a "flap compensator" nor is there a provision to add such a thing. If a customer detects a difference in the calibrated needle position as described in the instructions between clean and flap-extended conditions, the suggestion is to mark the dial face for the maximum difference between the two conditions.

Q: Does the needle go far enough to the right for a best glide mark?

For most aircraft, best glide is approximately the best rate of climb speed which I would think would fall at the low third of the green arc for most single engine aircraft. Full scale deflection to the right (top of the green arc) will occur around 80-85 knots with typical customer calibration - meaning that at the junction of the red and white arcs, you should experience only a marginal ability to still climb at a set throttle position when adding back pressure on the stick - the definition of “marginal” being the pilot’s comfort level in that situation. Aircraft stall will occur significantly into the red at that setting.

The range of absolute airspeed between “marginal climb” and best rate of climb / best glide will vary by aircraft, but the relative relationship should be well contained within the gauge range of red/white junction to significantly below full-scale deflection to the right once calibrated.

Q: What size hole is really needed in the panel? frustrated that this is advertised as a 2-1/4 application then to find a larger hole, cutting die, is needed.

Per the installation manual, the hole must be cut to 2-5/8 inches.

Q: Can you T into one of the lines for the airspeed indicator?

Yes. This unit comes with the probe necessary to have it function.
